    static void Main(string[] args)
    {
        IntPtr pInfo = IntPtr.Zero;
        uint count = 0;
        Int32 dataSize = Marshal.SizeOf(typeof(WTS_SERVER_INFO));
        if (WTSEnumerateServers(null, 0, 1, ref pInfo, ref count))
        {
        Int64 current = (int)pInfo;
        for (int i = 0; i < count; i++)
