Question

想要在运行我的Wifi个人资料添加代码时询问您对此错误的看法。

现在您看到的代码是我正在使用的示例（因为我是C＃中Wlan界面的新手）。

我正在尝试将wlan功能添加到我的程序中，该程序将搜索某个无线网络，将该配置文件添加到PC并连接它（ping测试 - 让这个工作正常）。

请参阅图片了解错误：here 我发现如果我从Windows文件夹中删除Cheesecake配置文件，则不会发生错误。这告诉我错误可能是因为已经存储了配置文件。但不确定。

我在这里附上我的示例代码以及FYI。任何帮助将不胜感激。

        {
            Wlan.WlanAvailableNetwork[]networks = wlanIface.GetAvailableNetworkList(0);
            foreach (Wlan.WlanAvailableNetwork network in networks)
            {
                Wlan.Dot11Ssid ssid = network.dot11Ssid;
                string networkName = Encoding.ASCII.GetString(ssid.SSID, 0, (int)ssid.SSIDLength);

Answer 1

我想我可能已经解决了这个问题，但我不确定它会产生什么影响。

我使用的是Managed Wifi API，在WlanAPI.cs中，有一行代码可以检查返回代码的大小。这是一行：

 int expectedSize = Marshal.SizeOf(typeof(Wlan.WlanReasonCode));

我发现的是，当原因代码为＆＃34;成功＆＃34;时，它的枚举值为0.所以我对该行进行了注释并在下一行中添加了零：

                            //int expectedSize = Marshal.SizeOf(typeof(Wlan.WlanReasonCode));
                            //if (notifyData.dataSize >= expectedSize)
                            //{
                            //    Wlan.WlanReasonCode reasonCode = (Wlan.WlanReasonCode) Marshal.ReadInt32(notifyData.dataPtr);
                            //    if (wlanIface != null)
                            //        wlanIface.OnWlanReason(notifyData, reasonCode);
                            //}

到

//int expectedSize = Marshal.SizeOf(typeof(Wlan.WlanReasonCode));
                            if (notifyData.dataSize >= 0)
                            {
                                Wlan.WlanReasonCode reasonCode = (Wlan.WlanReasonCode)Marshal.ReadInt32(notifyData.dataPtr);
                                if (wlanIface != null)
                                    wlanIface.OnWlanReason(notifyData, reasonCode);
                            }

这似乎有效，但我不确定我是否打开了一罐蠕虫。你们能想到其他更好的解决方案吗？

谢谢，垫
