使用C#连接wifi

需要安装库

Managed Native Wifi

获取Wifi列表

示例代码

private List<AvailableNetworkPack> GetAvaliableNetworks()
{
    var networks = new List<AvailableNetworkPack>();
    foreach (var network in NativeWifi.EnumerateAvailableNetworks())
    {
        if (!networks.Contains(network))
        {
            networks.Add(network);
        }
    }
    return networks;
}

创建Profile

应该支持这些类型open, WEP and WPA-PSK的网络

private static string CreateSecurityWifiProfile(string ssid, string password)
        {
            string hex = CreateHexSSIDName(ssid);

            return string.Format(@"<?xml version=""1.0""?>

连接到wifi

 var networks = GetAvaliableNetworks();
var network = networks.First(n => n.Ssid.ToString() == "gophers");
var profile = NativeWifi.EnumerateProfiles().FirstOrDefault(x => x.Name == "NTSP_CD");

if (profile is null)
{
    var profileXml = CreateProfile("gophers", "gopherspwd");
    // create a profile
    var profileResult = NativeWifi.SetProfile(network.Interface.Id, ProfileType.PerUser, profileXml, "AES", true);
}
// do connect
var wasConnected = NativeWifi.ConnectNetwork(network.Interface.Id, network.Ssid.ToString(), network.BssType);

命令行连接WiFi

下面是不同的平台调用命令行进行wifi控制的例子：

linux

连接wifi nmcli d wifi connect ssidxxx password passwordxxx ifname xxxxinterface

断开连接 nmcli d disconnect ifname xxxxinterface

检查wifi是否开启 nmcli radio wifi 判断返回值中是否包含"enabled" 开启wifi nmcli radio wifi on 关闭wifi nmcli radio wifi off

mac

连接wifi networksetup -setairportnetwork xxxxinterface ssidxxx passwordxxx 断开WiFi networksetup -removepreferredwirelessnetwork xxxxinterface

检查wifi是否开启 networksetup radio wifi 判断返回值中是否包含"enabled" 开启wifi networksetup -setairportpower on 关闭wifi networksetup -setairportpower off

windows

写配置文件然后 netsh wlan add profile filename=profilePath

连接wifi netsh wlan connect name=ssidxxx 检查WiFi是否开启 netsh wlan show interface name="Wireless Network Connection"是否包含 ““There is no wireless interface”” 开启wifi netsh wlan set interface name="Wireless Network Connection" ENABLED 关闭wifi netsh wlan set interface name="Wireless Network Connection" DISABLED

断开连接 netsh wlan disconnect
