Call native Delphi code from C#

Question

Are there any best practices to call native C++ or Delphi Dlls from C# (ASP.NET)? Is invoking or a COM interop the best way to access those Dlls?

Answer 1

You can use DllImport to achieve your objective, as per the following:

[DllImport("kernel32.dll")]
public static extern IntPtr OpenProcess(uint dwDesiredAccess, bool bInheritHandle, int dwProcessId);

You can use this with any Win32 compatible DLL, including Delphi ones.
