C#打开WiFi热点,WiFi共享的四种方式总结(二)
拚忘的博客园要开始写随笔了,第一期就先讲讲wifi热点吧.....
持续更新C#、wpf、.NetCore相关内容,欢迎关注!!

C#打开WiFi热点,WiFi共享的四种方式总结(四)
C# Windows系统 ,WiFi共享的方式,打开WiFi热点我最近研究总结了又四种方式开启。
1.通过netsh wlan命令行开启
2.通过wlanapi接口共享
3.通过Win10 Api开启,Windows.Devices.WiFiDirect
4.通过Win10 api,Windows.Networking.NetworkOperators.NetworkOperatorTetheringManager 开启电脑自带的热点。
二、通过windows提供的wlanapi.dll来开启热点共享。
微软也是提供了操作netsh的相关接口,其实原理和通过Cmd操作netsh wlan是一样的同样也需要网卡支持承载,一般Win10现在很多网卡不支持。
通过CMD的方式参考上文:https://www.cnblogs.com/panwangvie/p/14878148.html
具体API参考文档:http://www.pinvoke.net/default.aspx/wlanapi.wlanconnect
需要用到的api如下:

启动流程:
private static void Start() { Close(); Try(() => { WlanHostedNetworkReason reason; Console.Write("启用托管网络中……"); reason = WlanManager.SetEnabled(true); if (reason != WlanHostedNetworkReason.Success) { Close(); return; } Console.Write("正在应用设置……"); reason = WlanManager.SetConnectionSettings(ssid, peersCount); if (reason != WlanHostedNetworkReason.Success) { WriteReason(reason); Close(); return; } var keyString = key as string; reason = keyString != null ? WlanManager.SetSecondaryKey(keyString) : WlanManager.SetSecondaryKey((byte[]) key); if (reason != WlanHostedNetworkReason.Success) { Close(); return; } Console.Write("启动共享中……"); WlanManager.ForceStart() ; }, Close); }
