如何在 .net 中获取可用的 wifi AP 及其信号强度？

有没有办法使用.NET 访问所有 WiFi 接入点及其各自的 RSSI 值？如果我可以在不使用非托管代码的情况下完成它，那就太好了，或者如果它可以在 Mono 和 .NET 中工作，那就更好了。

如果可能的话，我将不胜感激代码示例。 谢谢

以下是我发现的一些类似的 stackoverflow 问题：

-获取我在 Windows Vista 上使用 C# .Net 连接到的无线网络的 SSID https://stackoverflow.com/questions/431755/get-ssid-of-the-wireless-network-i-am-connected-to-with-c-net-on-windows-vista

-在 C# 中管理无线网络连接 https://stackoverflow.com/questions/285665/managing-wireless-network-connection-in-c

-从 C# 获取无线接入点的 BSSID（MAC 地址） https://stackoverflow.com/questions/187777/get-bssid-mac-address-of-wireless-access-point-from-c

它是一个包装项目，其中包含 C# 中的托管代码，位于http://www.codeplex.com/managementwifi http://www.codeplex.com/managedwifi

它支持Windows Vista和XP SP2（或更高版本）。

示例代码：

using NativeWifi;
using System;
using System.Text;

namespace WifiExample
{
    class Program
    {
        /// <summary>
        /// Converts a 802.11 SSID to a string.
        /// </summary>
        static string GetStringForSSID(Wlan.Dot11Ssid ssid)
        {
            return Encoding.ASCII.GetString( ssid.SSID, 0, (int) ssid.SSIDLength );
        }

        static void Main( string[] args )
        {
            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 )
                {
                    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 );
                }

                // Connects to a known network with WEP security
                string profileName = "Cheesecake"; // this is also the SSID
                string mac = "52544131303235572D454137443638";
                string key = "hello";
                string profileXml = string.Format("<?xml version=\"1.0\"?><WLANProfile xmlns=\"http://www.microsoft.com/networking/WLAN/profile/v1\"><name>{0}</name><SSIDConfig><SSID><hex>{1}</hex><name>{0}</name></SSID></SSIDConfig><connectionType>ESS</connectionType><MSM><security><authEncryption><authentication>open</authentication><encryption>WEP</encryption><useOneX>false</useOneX></authEncryption><sharedKey><keyType>networkKey</keyType><protected>false</protected><keyMaterial>{2}</keyMaterial></sharedKey><keyIndex>0</keyIndex></security></MSM></WLANProfile>", profileName, mac, key);

                wlanIface.SetProfile( Wlan.WlanProfileFlags.AllUser, profileXml, true );
                wlanIface.Connect( Wlan.WlanConnectionMode.Profile, Wlan.Dot11BssType.Any, profileName );
            }
        }
    }
}
