下载Managed Wifi API
创建C#工程文件，并添加对ManagedWifi.dll的引用。
编写代码，引用“Native Wifi API”。关键代码如下：
using System;using System.Collections.Generic;using System.Text;using NativeWifi; namespace ManagedWifiExample{ 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> /// 枚举所有无线设备接收到的SSID /// </summary> public void ScanSSID() { 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) { WIFISSID targetSSID = new WIFISSID(); targetSSID.wlanInterface = wlanIface; targetSSID.wlanSignalQuality = (int)network.wlanSignalQuality; targetSSID.SSID = GetStringForSSID(network.dot11Ssid); //targetSSID.SSID = Encoding.Default.GetString(network.dot11Ssid.SSID, 0, (int)network.dot11Ssid.SSIDLength); targetSSID.dot11DefaultAuthAlgorithm = network.dot11DefaultAuthAlgorithm.ToString(); targetSSID.dot11DefaultCipherAlgorithm = network.dot11DefaultCipherAlgorithm.ToString(); ssids.Add(targetSSID); //if ( network.dot11DefaultCipherAlgorithm == Wlan.Dot11CipherAlgorithm.WEP ) //{ // Console.WriteLine( "Found WEP network with SSID {0}.", GetStringForSSID(network.dot11Ssid)); //} //Console.WriteLine("Found network with SSID {0}.", GetStringForSSID(network.dot11Ssid)); //Console.WriteLine("dot11BssType:{0}.", network.dot11BssType.ToString()); //Console.WriteLine("dot11DefaultAuthAlgorithm:{0}.", network.dot11DefaultAuthAlgorithm.ToString()); //Console.WriteLine("dot11DefaultCipherAlgorithm:{0}.", network.dot11DefaultCipherAlgorithm.ToString()); //Console.WriteLine("dot11Ssid:{0}.", network.dot11Ssid.ToString()); //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()); //Console.WriteLine("profileName:{0}.", network.profileName.ToString()); //Console.WriteLine("wlanNotConnectableReason:{0}.", network.wlanNotConnectableReason.ToString()); //Console.WriteLine("wlanSignalQuality:{0}.", network.wlanSignalQuality.ToString()); //Console.WriteLine("-----------------------------------"); // Console.WriteLine(network.ToString()); } } } // EnumSSID /// <summary> /// 连接到未加密的SSID /// </summary> /// <param name="ssid"></param> public void ConnectToSSID(WIFISSID ssid) { // Connects to a known network with WEP security string profileName = ssid.SSID;

ssid.wlanInterface.SetProfile(Wlan.WlanProfileFlags.AllUser, myProfileXML, true); ssid.wlanInterface.Connect(Wlan.WlanConnectionMode.Profile, Wlan.Dot11BssType.Any, profileName); //Console.ReadKey();

public string dot11DefaultAuthAlgorithm = ""; public string dot11DefaultCipherAlgorithm = ""; public bool networkConnectable = true; public string wlanNotConnectableReason = ""; public int wlanSignalQuality = 0;

Wifi XML配置文件请参考微软文档
