DC Invalid when trying to download image

When I call GetFile() I am getting the following error.. It is an image that I am trying to download...

Throwing exception for request AuthExportAuthorizationRequest because of error BadRequest - DC_ID_INVALID

Подскажите пожалуйста, что такое from_id

Помогите пожалуйста разобраться с структуре MessageConstructor.

В поле to_id - идентификатор пира отправителя сообщения. С этим всё понятно. Но вот в поле from_id - неизвестный номер, который я не знаю, как соотнести с получателем.

В результате, когда я получаю updates_Difference с отправленными мной же сообщениями, я не знаю, кому они были отправлены.

Например:

Я получаю следующий Message
(message id:259 from_id:1590 to_id:188888888 out:False unread:False date:1474534709 message:'тестовое сообщение' media:(messageMediaEmpty))
188888888 - это мой ID, так как это сообщение отправлял я. Но кому это сообщение было мной отправлено, я понять из этих данных не могу. Как мне соотнести с id'ом или from_id'ом идентификатор того пира, которому это сообщение предназначалось?

Invalid constructor code 388FA391 error when trying to use GetDialog

I want to get a chat by its name and send message to the chat.
My code is as below:

        int id = 0;
        var client = await InitializeAndAuthenticateClient();
        var chatlist = await client.GetDialogs(0, 10, 0) as MessagesDialogsConstructor;
        foreach (Chat A in chatlist.chats)
        {

            var chatreq = A as ChatConstructor;

            if (chatreq.title == "chatname")
            {
                id= chatreq.id;
                break;
            }



         }

        if(id!=0)
        {

            await client.SendChatMessage(id, "hello");

        }

but I get this error: "Invalid constructor code 388FA391 " .
How can I fix this? Or any other suggestion to get the chat id?
Thanks.

How to send messages to the group? 

[TestMethod]
        public async Task CreateChatAndSendMessage()
        {
            var client = await InitializeClient();

            var chatName = Guid.NewGuid().ToString();
            var statedMessage = await client.CreateChat(chatName, new List<string> { NumberToSendMessage });

            var createdChat = GetChatFromStatedMessage(statedMessage);

Read unread message and set them as read or delete them

I try your library and it is awesome. It's more stable than other telegram libraries. The features like auto reconnect is very helpful.
I have no idea about sending rpc request to read unread messages and set them as read or delete them. Here's the code I'm using
If I subscribe to the UpdateMessage event then the Flood - FLOOD_WAIT_19 occurs where I have to wait 19 seconds to read next incoming text message. No idea how to read unread message without FLOOD_WAIT :(

to set message as read - no luck

var requestConfirmed = new ReceivedMessagesRequest(messageId)
{
    ConfirmReceived = true
};
await client.SendRpcRequest(requestConfirmed);

to delete message - no luck

var requestDelete = new DeleteMessagesRequest(new List<int> { messageId });
await client.SendRpcRequest(requestDelete);

One more. After creating new instance of TelegramClient and calling client.Start(); the UpdateMessage event is not fired untill I send message first then back to normal (UpdateMessage fired again)

client.SendCode(...) error

Help please,
I'm trying to use Telegram.NET, I've created developer account at telegram website and got my Api ID and Api Hash so far so good.

i'm able to perform client.Start() and it returns me "connected"

after that I got to client.SendCode() and it returns me an exception which says API_ID_INVALID.
i know how to copy and paste so i am pretty sure its not a number mistake..

it worked once on my friend computer when i used it without DeviceInfo so ill be glad if someone can send me an example of :
DeviceInfo(string deviceModel, string systemVersion, string appVersion, string langCode)

another option is the server, in my app configuration page on telegram i get 2 servers which are different than your default server:
TEST SERVER :
149.154.167.40:443
PROD SERVER:
149.154.167.50:443

tried them both but it still returns me API_ID_INVALID
any suggestions ?

How to get channel updates?

Hello,

I would like to get channel updates.
I have used the sample code you provided in issue #25, but I didn't get any update when a channel get a new post.

FileSessionStore session = new FileSessionStore();
client = new TelegramClient(session, apiId, apiHash, new DeviceInfo("Telegram Test", "Telegram Test", "1.0", "en"));

Error when trying to send a message

Hello,

I am trying to send a message to a telegram bot using the following code:

   public async Task SendMessageByUserName(TelegramClient client, string command)
    {
        var user = await client.ResolveUsername(userName) as UserForeignConstructor;
        var peer = new InputPeerForeignConstructor() { userId = user.id };
        var message = await client.SendMessage(peer, command);
    }

I am getting the following error: {"BadRequest - PEER_ID_INVALID"}
Would you please clarify what I am doing wrong?

I also see that there is the second parameter in the InputPeerForeignConstructor class (accessHash) but I am not sure how to get it and whether I need it.

Thanks

HTTP Transport. Need help.

Now Telegram.Net supports one transport (TCP). I would try to write another transport (HTTP).

Someone tell me where best to start, and which way to go? =)

I tried, but it was stuck. Maybe someone will tell you where I'm confused.
I am trying to implement the http-transport. When you try to get the answer - Error 404.

    public class HttpTransport : ITransport, IDisposable
    {
        private readonly HttpWebRequest httpWebRequest;
        private int sendCounter = 0;

        public HttpTransport(string address, int port)
        {
            httpWebRequest = (HttpWebRequest)WebRequest.Create("http://" + address);
        }

        public async Task Send(byte[] packet)
        {
            var data = packet;

            httpWebRequest.Method = "POST";
            httpWebRequest.ContentType = "application/x-www-form-urlencoded ; charset=UTF-8";
            httpWebRequest.ContentLength = data.Length;

            using (var stream = httpWebRequest.GetRequestStream())
            {
                await stream.WriteAsync(data, 0, data.Length);
            }

            sendCounter++;
        }

        public async Task<TcpMessage> Receieve()
        {
            var response = (HttpWebResponse)httpWebRequest.GetResponse();
            var stream = response.GetResponseStream();

            var packetLengthBytes = new byte[4];
            if (await stream.ReadAsync(packetLengthBytes, 0, 4) != 4)
                throw new InvalidOperationException("Couldn't read the packet length");
            int packetLength = BitConverter.ToInt32(packetLengthBytes, 0);

            var seqBytes = new byte[4];
            if (await stream.ReadAsync(seqBytes, 0, 4) != 4)
                throw new InvalidOperationException("Couldn't read the sequence");
            int seq = BitConverter.ToInt32(seqBytes, 0);

            int readBytes = 0;
            var body = new byte[packetLength - 12];
            int neededToRead = packetLength - 12;

            do
            {
                var bodyByte = new byte[packetLength - 12];
                var availableBytes = await stream.ReadAsync(bodyByte, 0, neededToRead);
                neededToRead -= availableBytes;
                Buffer.BlockCopy(bodyByte, 0, body, readBytes, availableBytes);
                readBytes += availableBytes;
            }
            while (readBytes != packetLength - 12);

            var crcBytes = new byte[4];
            if (await stream.ReadAsync(crcBytes, 0, 4) != 4)
                throw new InvalidOperationException("Couldn't read the crc");
            int checksum = BitConverter.ToInt32(crcBytes, 0);

            byte[] rv = new byte[packetLengthBytes.Length + seqBytes.Length + body.Length];

            Buffer.BlockCopy(packetLengthBytes, 0, rv, 0, packetLengthBytes.Length);
            Buffer.BlockCopy(seqBytes, 0, rv, packetLengthBytes.Length, seqBytes.Length);
            Buffer.BlockCopy(body, 0, rv, packetLengthBytes.Length + seqBytes.Length, body.Length);
            var crc32 = new Ionic.Crc.CRC32();
            crc32.SlurpBlock(rv, 0, rv.Length);
            var validChecksum = crc32.Crc32Result;

            if (checksum != validChecksum)
            {
                throw new InvalidOperationException("invalid checksum! skip");
            }

            return new TcpMessage(seq, body);
        }
    }

OnMessage not working after restart the Application

This is my Code. On first run everything worked correctly. But when the program is closed and reopened again than UpdateHandler not get called anymore. client.IsUserAuthorized() gives true. When i delete Session.dat i can reenter my code and it will work. After 5 runs of the programm i have to wait 24 hours because of flood error.

    public class Program
    {
        static void Main(string[] args)
        {
                Program program = new Program();
                Task.Run(async () => await program.Run()).Wait();
        }

        public async Task Run()
        {
                TelegramClient client = new TelegramClient(new FileSessionStore(), 129340, "...", new DeviceInfo("Telegram Test", "Telegram Test", "Telegram Test", "en"));
                client.UpdateMessage += UpdateHandler;
                await client.Start();
                if (!client.IsUserAuthorized())
                {
                    var codeRequest = await client.SendCode("+...", VerificationCodeDeliveryType.NumericCodeViaTelegram);
                    string input = "";
                    await client.SignIn("+...", codeRequest.phoneCodeHash, input);
                }
        }

        private void UpdateHandler(object sender, Updates updates)
        {
            if (updates.constructor == Constructor.UpdateShortMessage)
            {
                var updateShortMessageConstructor = updates as UpdateShortMessageConstructor;
            }
        }
    }

How to set message as read?

I added class "ReadMessageRequest" like this:

using System.Collections.Generic;
using System.IO;
using Telegram.Net.Core.MTProto;

namespace Telegram.Net.Core.Requests
{
    public class ReadMessagesRequest : MtProtoRequest
    {
        public readonly List<int> messageIdsToRead;
        public List<int> readMessageIds { get; private set; }

        public ReadMessagesRequest(List<int> messageIdsToRead)
        {
            this.messageIdsToRead = messageIdsToRead;
        }

        protected override uint requestCode => 0xc6649e31;

        public override void OnSend(BinaryWriter writer)
        {
            writer.Write(requestCode);
            TLObject.WriteVector(writer, messageIdsToRead, writer.Write);
        }

        public override void OnResponse(BinaryReader reader)
        {
            readMessageIds = TLObject.ReadVector(reader, reader.ReadInt32);
        }

        public override bool isContentMessage => true;
    }
}

Then i tried code like this to set message as read:

private async void btnSetMessageRead_Click(object sender, EventArgs e)
{
     List<int> fmsgid = new List<int>();
     fmsgid.Add(14);
     var setreadmessage = new ReadMessagesRequest(fmsgid);
     await client.SendRpcRequest(setreadmessage);
}

but i got Unhandled exception : "BadRequest - INPUT_METHOD_INVALID"
please how to resolve it?
thx...

Enabling session after publication in IIS

After generating the " core.dll " as should be created " session.data " when you published the application in IIS ?

Because at this point I will have to inform the received code.
