VB to c# conversion

[Jeremy Martin]

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

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
