VB to c# conversion

Does anyone know what the c# equivalent of this would be?

VB Code:

Declare Function TWAIN_AcquireToFilename Lib "EZTW32.DLL" (ByVal hwndApp As Short, ByVal bmpFileName As String) As Short
    Declare Function TWAIN_SelectImageSource Lib "EZTW32.DLL" (ByVal hwndApp As Integer) As Integer
    Declare Function TWAIN_AcquireToClipboard Lib "EZTW32.DLL" (ByVal hwndApp As Integer, ByVal wPixTypes As Integer) As Integer
    Declare Function TWAIN_IsAvailable Lib "EZTW32.DLL" () As Integer
    Declare Function TWAIN_EasyVersion Lib "EZTW32.DLL" () As Integer

Code:

---

using System;
using System.Runtime.InteropServices;
namespace Win32Application
{

public class Win32
{
[DllImport("User32.dll")]
public static extern Int32 FindWindow(String lpClassName,String lpWindowName);

[DllImport("EZTW32.DLL")]
public static extern Int32 TWAIN_AcquireToFilename(int hwndApp, string bmpFileName);


....
...

}
