Somebody could tell me how to declare winapi in c#? I'm having this error:

Error   1   The name 'WinApi' does not exist in the current context bla bla bla...

in line:

 WinApi.OpenProcess(WinApi.PROCESS_ALL_ACCESS, 0, (uint)aProc[0]);

If you're not using a library that provides those methods and constants, you'll need to implement them yourself using Platform Invocation Services (P/Invoke).

For example:

public static class WinApi {
    public const int PROCESS_ALL_ACCESS = /* whatever the value is */;

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