Any extension method for coping the entire contents of a directory? about z.extensionmethods

You can look at DirectoryInfo.CopyTo extension methods:

https://github.com/zzzprojects/Z.ExtensionMethods/blob/master/src/Z.IO/System.IO.DirectoryInfo/DirectoryInfo.CopyTo.cs

You can specify the search pattern and search options (if you want to include child directories)

Thanks, I found this method.
But it cannot override existing files.

You are right,

We will add an overload eventually to allow to override existing file. Meanwhile, you can easily fix it by importing the method in your project and add the "true" value to the CopyTo method.

    public static void CopyTo(this DirectoryInfo obj, string destDirName, string searchPattern, SearchOption searchOption)
    {
        var files = obj.GetFiles(searchPattern, searchOption);
        foreach (var file in files)
        {
            var outputFile = destDirName + file.FullName.Substring(obj.FullName.Length);
            var directory = new FileInfo(outputFile).Directory;

            if (directory == null)
            {
                throw new Exception("The directory cannot be null.");
            }

            if (!directory.Exists)
            {
                directory.Create();
            }

            file.CopyTo(outputFile, true);
        }

        // Ensure empty dir are also copied
        var directories = obj.GetDirectories(searchPattern, searchOption);
        foreach (var directory in directories)
        {
            var outputDirectory = destDirName + directory.FullName.Substring(obj.FullName.Length);
            var directoryInfo = new DirectoryInfo(outputDirectory);
            if (!directoryInfo.Exists)
            {
                directoryInfo.Create();
            }
        }
    }
