被要求把vb的这段程序用c#重写，可俺c#都还很菜，vb完全不懂 = =+

我查了一下说是On Error Resume Next 是遇到错误也跳过去继续向下执行，似懂非懂...
源代码如下，这里在c#该怎么处理呢？ try catch？？

拜谢各位大侠指点。。。。 (┬＿┬)

   Private Sub CS_GetWinSockERR()
        Dim msg As String
        Dim WSDesc As New VB6.FixedLengthString(128)
        Dim WSErrno As Short

        Error_No = CF_winsockerror(WSErrno, WSDesc.Value, Len(WSDesc.Value))
        If (WSErrno <> 0) Then 'WSErrno = 0: no winsock error
            MsgBox(Trim(WSDesc.Value), , G_STARVSNSQL)
        End If
    End Sub

    Public Function CF_winsockerror(ByRef WSErrorNo As Short, ByRef WSErrorDesc As String, ByRef WSErrorLen As Short) As Short
        On Error Resume Next
        error_no = ltWinSockError(CInt(WSErrorNo), WSErrorDesc, CInt(WSErrorLen))
        CF_winsockerror = CShort(error_no)
    End Function
