C# using C++ dlls and lib

[tshad]

I have a program in C# that needs to access a couple of C++ dlls and libs.

Can this be done?

Thanks,

Tom

You can only call functions exported by DLL's, C# (and all other .NET
languages) cannot bind to libs.
Note also that with "exports" I mean C style exported functions. Search the
docs for PInvoke interop for more details.

COM DLL's or Win32 DLL's.

COM stuff can be used directly.

Win32 DLL's can be used via dllimport.

A very simple example:

using System;
using System.Runtime. InteropServices ;

class MainClass
{
[DllImport("msvc rt.dll")]
public static extern int system(string cmd);
public static void Main(string[] args)
{
Console.WriteLi ne("Hello world");
system("CLS");
}
}

Good point.

C++ mangled names is a problem.
