VB to C# translation

Question

Hello All I understand that all the .net languages sit upon a common underlying layer. I was wondering if any one could translate the following VB code into C#? Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal _ hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, _ lParam As Any) As Long Const EM_GETFIRSTVISIBLELINE = &HCE FirstVisibleLine = SendMessage(Text1.hwnd, EM_GETFIRSTVISIBLELINE, 0, ByVal 0&) The code should return the index of the topmost line displayed in a rich text box.
