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][https_my.oschina.net_tianma3798_blog_846727]

3.CodeFlex源代码地址：[http://managedwifi.codeplex.com/][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][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][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][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][http_www.pinvoke.net_default.aspx_wlanapi.wlanconnect]

3.Wireless Profile Samples：[https://msdn.microsoft.com/en-us/library/aa369853(v=vs.85).aspx][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][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);  
            }  
        
            /// <summary>

                        //Console.WriteLine("flags:{0}.", network.flags.ToString());  
                        //Console.WriteLine("morePhyTypes:{0}.", network.morePhyTypes.ToString());  
                        //Console.WriteLine("networkConnectable:{0}.", network.networkConnectable.ToString());  
                        //Console.WriteLine("numberOfBssids:{0}.", network.numberOfBssids.ToString());

            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);
    }

![Center][]  
  
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：
