轉換vb.net代碼轉換爲C＃.NET

Question

誰能PLZ這個VB .NET代碼轉換爲C＃.NET

我試圖在www.developerfusion.com，他們這是給錯誤。

Public Declare Function SCardListReaders Lib "Winscard.dll" Alias "SCardListReadersA" (ByVal hContext As Integer, ByVal mzGroup As String, ByVal ReaderList As String, ByRef pcchReaders As Integer) As Integer 

Answer 1

簡單：

[DllImport("Winscard.dll", CharSet = CharSet.Unicode, EntryPoint = "SCardListReadersW", ExactSpelling = true, SetLastError = true)] 
public static extern int SCardListReaders(int hContext, [MarshalAs(UnmanagedType.VBByRefStr)] ref string mzGroup, [MarshalAs(UnmanagedType.VBByRefStr)] ref string ReaderList, ref int pcchReaders); 

確實。
