C# library to load a native DLL from memory without the need to allow unsafe code

DLLFromMemory.Net

A C# library to load a native DLL from memory without the need to allow unsafe code.

By default C# can load external libraries only via files on the filesystem. A common workaround for this problem is to write the DLL into a temporary file first and import it from there. This library can be used to load a DLL completely from memory - without storing on the disk first.

It supports both 32bit and 64bit processes/DLLs, as well as AnyCPU builds.
For AnyCPU, both 32bit and 64bit DLLs must be available in memory (see Sample)

Example

[UnmanagedFunctionPointer(CallingConvention.Cdecl)] delegate int AddDelegate(int a, int b);

static void RunAdd(byte[] dllBytes)
{
    DLLFromMemory dll = new DLLFromMemory(dllBytes);

    AddDelegate addFunc = dll.GetDelegateFromFuncName<AddDelegate>("Add");
    Console.WriteLine("Calling add(1, 2): " + addFunc(1, 2) + "\n");

    dll.Close();
}
