        /// 客户端MAC地址列表
        /// </summary>
        public IList<string> Clients { get { return clients; } }
    }
}

调用端代码如下:

   
VWirelessNetworkManager vwifi;
vwifi = new VWirelessNetworkManager(); vwifi.VWirelessSetted += Vwifi_VWirelessSetted; vwifi.VWirelessStarted += Vwifi_VWirelessStarted; vwifi.VWirelessStopped += Vwifi_VWirelessStopped; vwifi.VWirelessChecking += Vwifi_VWirelessChecking;

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;
        }
