调用端代码如下：
VWirelessNetworkManager vwifi;比较重要的是下面这个是下面这个事件的返回值,他决定了是否一直循环检查虚拟无线网络的是否正常。private bool Vwifi_VWirelessChecking(object sender, VWirelessNetworkCheckEventArgs e)
{
bool isContinueChecking = false;
if (e.ErrorTexts.Count > 0)
{
string topErrorText = string.Format("{0}，重试请按确定，退出请按取消，谢谢！", e.ErrorTexts[0]);
if (MessageBox.Show(topErrorText, "错误", MessageBoxButtons.OKCancel, MessageBoxIcon.Error) == DialogResult.Cancel)
{
Application.Exit();
}
isContinueChecking = true;
}
return isContinueChecking;
}
