Windows 10 操作系统下利用USB无限网卡创建虚拟WirelessNetwork 类的封装

最近因为公司的业务要求，在没有网络的情况下，没有路由器支持的情况下，需要组建一个小局域网，可以同时支持多个终端的相互之间的通信，这里的解决方案如下。

一、硬件要求：任意支持软AP的无限网卡，具体是否支持请输入命令行如下查看，如图（一）：

图（一）

根据上图，包含 C:\Windows\system32\DRIVERS\vwifibus.sys即可支持软AP。

二、熟悉命令

1.设置并允许虚拟无线网路；

命令：netsh 命令符下输入 wlan set hostednetwork mode = allow ssid=无线名称 key=无线密码（8位数）

返回结果：承载网络模式已设置为允许。
已成功更改承载网络的 SSID。
已成功更改托管网络的用户密钥密码。

2.显示设置的虚拟网络信息；

命令：netsh 命令符下输入 wlan show hostednetwork

返回结果：承载网络设置
-----------------------
    模式                   : 已启用
    SSID 名称              :“无线名称”
    最多客户端数  : 32
    身份验证         : WPA2 - 个人
    密码                 : CCMP


承载网络状态
---------------------
    状态                 : 未启动


netsh>

3.启动设置的无线网络

命令：netsh 命令符下输入 wlan start hostednetwork

4.停止设置的无线网络

命令：netsh 命令符下输入 wlan stop hostednetwork

5.禁止设置的无线网络

命令：命令：netsh 命令符下输入 wlan set hostednetwork mode=disallow

返回结果：承载网络模式已设置为禁止。

三、对应封装的C#类，代码如下：

    {
        private bool isEnableDynamicKey = false;
        private string cleartextKey = null;


        public event EventHandler<VWirelessNetworkEventArgs> VWirelessStarted;

            };

        }

        {

                    //this.lstboxMessage.Items.Add("消息：动态生成密码功能未开启，以明文密码方式并创建虚拟无限网络！");
                    vwifi.SetVWirelessInfo(string.Format("SmTR-{0}", DateTime.Now.ToString("HHmmssfffffff")), DateTime.Now.ToOADate().ToString());

                vwifi.StartVWirelessNet();
            }
            else
            {
                Application.Exit();
            }

五、说明

最后测试部分的动态密码的意思是提供不公开密码的情况下，根据规则自动计算的，具体方法可以自己修改。
