一、Managed Wifi API简介

1.这是一个.Net类库允许控制无线网络适配器（802.11）安装在你的Windows机器编程。

2.这个类库使用本地WiFi的API，不支持旧版本的Windows。wlanapi.dll更多参考：https://my.oschina.net/tianma3798/blog/846727

3.CodeFlex源代码地址：http://managedwifi.codeplex.com/

4.这个类库的wlanapi不是特别全....

5.更多wifi相关参考Msdn：https://technet.microsoft.com/zh-cn/network/bb545365

6.Native Wifi API Sample (Windows)，参考：https://msdn.microsoft.com/en-us/library/aa816369(v=vs.85).aspx

二、更多相关资料

1.C#与C++数据类型对应：http://www.cnblogs.com/zjoch/p/5999335.html

2.更多C# 的wlanapi接口对应：http://www.pinvoke.net/default.aspx/wlanapi.wlanconnect

3.Wireless Profile Samples：https://msdn.microsoft.com/en-us/library/aa369853(v=vs.85).aspx

4.WLAN_profile Schema Elements ，Xml文件介绍：https://msdn.microsoft.com/en-us/library/ms706965(v=vs.85).aspx

三、简单使用实例

1.引用 ManagedWifi.dll，using NativeWifi;

2.C#代码

   class MyWifi  
    {  
        public List<WIFISSID> ssids = new List<WIFISSID>();  
    
        public MyWifi()  
        {  
            ssids.Clear();  
        }  
    
    
        static string GetStringForSSID(Wlan.Dot11Ssid ssid)  
        {  
            return Encoding.UTF8.GetString(ssid.SSID, 0, (int)ssid.SSIDLength);  
        }

            foreach (WlanClient.WlanInterface wlanIface in client.Interfaces)  
            {  
                // Lists all networks with WEP security  
                Wlan.WlanAvailableNetwork[] networks = wlanIface.GetAvailableNetworkList(0);

        public int wlanSignalQuality = 0;  
        public WlanClient.WlanInterface wlanInterface = null;  
    }  
    
}

3.带密码的Xml文件

<?xml version="1.0" encoding="utf-8" ?>
<WLANProfile xmlns="http://www.microsoft.com/networking/WLAN/profile/v1">
  <name>nicaimimashisha</name>
  <SSIDConfig>
    <SSID>
      <hex>6E696361696D696D61736869736861</hex>
      <name>nicaimimashisha</name>
    </SSID>
  </SSIDConfig>
  <connectionType>ESS</connectionType>
  <connectionMode>auto</connectionMode>
  <MSM>
    <security>
      <authEncryption>
        <authentication>WPA2PSK</authentication>
        <encryption>AES</encryption>
        <useOneX>false</useOneX>
      </authEncryption>
      <sharedKey>
        <keyType>passPhrase</keyType>
        <protected>true</protected>
        <keyMaterial>01000000D08C9DDF0115D1118C7A00C04FC297EB010000004F479E51D4435D409C4B5FC05DF1BD2D000000000200000000001066000000010000200000005C53C70A83EBEA47512B9F87B34EC7C405E9B4ACDBFFFEBEA8B5DA6D6958E6A8000000000E8000000002000020000000F95172637168CC535A909A1CC8021C003077AD958B38C2C01F5B1CF6AB3F87B4100000005D3361250B2140E1B14D0F66D36F2CA640000000C49084078E63F00188D3CF0B80EE9127EEDFAEABAB01803D5E0480A89811E3B24FEF3EA45FF713BB9C244EABC1C2C119CAC4FE192ACF60C976027112262A4E3F</keyMaterial>
      </sharedKey>
    </security>
  </MSM>
  <MacRandomization xmlns="http://www.microsoft.com/networking/WLAN/profile/v3">
    <enableRandomization>false</enableRandomization>
  </MacRandomization>
</WLANProfile>

特别说明：keyMaterial必须是根据指定加密方法加密之后的数据

4.事件监听：

 wlanIface.WlanConnectionNotification += WlanIface_WlanConnectionNotification;

private static void WlanIface_WlanConnectionNotification(Wlan.WlanNotificationData notifyData,
    Wlan.WlanConnectionNotificationData connNotifyData)
{
    Console.WriteLine(".....................");
    Console.WriteLine(notifyData.NotificationCode);
    Console.WriteLine(notifyData.notificationSource);
}

4.获取已经连接过的Xml配置文件

WlanClient client = new WlanClient();
foreach (WlanClient.WlanInterface wlanIface in client.Interfaces)
{
// Lists all networks with WEP security
Wlan.WlanAvailableNetwork[] networks = wlanIface.GetAvailableNetworkList(0);
foreach (Wlan.WlanAvailableNetwork network in networks)
{
    //Console.WriteLine(network.profileName);
    //Console.WriteLine(GetStringForSSID(network.dot11Ssid));
    //Console.WriteLine(network.dot11DefaultCipherAlgorithm);
    //Console.WriteLine("*********************************");

    //if (network.dot11DefaultCipherAlgorithm == Wlan.Dot11CipherAlgorithm.WEP)
    //{
    //    Console.WriteLine("Found WEP network with SSID {0}.", GetStringForSSID(network.dot11Ssid));
    //}
}

// Retrieves XML configurations of existing profiles.
// This can assist you in constructing your own XML configuration
// (that is, it will give you an example to follow).
foreach (Wlan.WlanProfileInfo profileInfo in wlanIface.GetProfiles())
{
    string name = profileInfo.profileName; // this is typically the network's SSID
    string xml = wlanIface.GetProfileXml(profileInfo.profileName);
    Console.WriteLine("ssid:" + name);
    Console.WriteLine(xml);
    Console.WriteLine("******************************************************");
}

}

获取结果：
