How can I get the P/Invoke definitions for Windows API functions?

Question

I want to use functions from the Win32 API in my .NET application, but I don't know the signature of the methods declared in the DLL files. If I use DllImport , I have to provide a definition of the method in order to use it as an "extern method".

Or is there another way to do this?

Answer 1

You could have a look at pinvoke.net , it is a collection of methods supported by various Win32 apis. Also it contains programs which can generate DllImport signatures if you have the C-style header.

Answer 2

Most Win32 API signatures are listed here .

Or you could try DLL Export Viewer .
