VB to C# rewriting question

Question

I have a following method declaration in VB and need to translate it into C#:

<DllImport("winspool.Drv", EntryPoint:="OpenPrinterW", _
   SetLastError:=True, CharSet:=CharSet.Unicode, _
   ExactSpelling:=True, CallingConvention:=CallingConvention.StdCall)> _
Public Shared Function OpenPrinter(ByVal src As String, ByRef hPrinter As IntPtr, ByVal pd As Int16) As Boolean
End Function

Particularly I am not sure if it the ByRef argument specifier is equivalent to ref is C#.
Also I don't know if Shared == static and whether it must be extern. Probably lot of you are proficient in both VB and C#, so I'd be grateful for providing correct declaration in C#.

Answer 1

check signature here: http://pinvoke.net/default.aspx/winspool/OpenPrinter.html

Answer 2

Particularly I am not sure if it the ByRef argument specifier is equivalent to ref is C#. Also I don't know if Shared == static and whether it must be extern.

Yes, all of these assumtions are correct:

[DllImport("winspool.Drv", EntryPoint="OpenPrinterW",
   SetLastError = true, CharSet = CharSet.Unicode,
   ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern bool OpenPrinter(string src, ref IntPtr hPrinter, Int16 pd);

(In fact, ByRef can correspond to either ref or out but since I don’t know which is required here I’m going with the more general ref – this is guaranteed to work).
