Yes. Using platform invoke, .NET Framework programs can access native code libraries by means of static DLL entry points.

Here is an example of C# calling the Win32 Message Box function:

using System;

using System.Runtime.InteropServices;

class MainApp

{

[DllImport("user32.dll", EntryPoint="MessageBox")]

public static extern int MessageBox(int hWnd, String strMessage, String strCaption, uint uiType);

public static void Main()

{

MessageBox( 0, "Hello, this is PInvoke in operation!", ".NET", 0 );

}

}
