如何使用WMI或System.Net.NetworkInformation Windows 10在C#中获取当前已连接的WiFi SSID? [英] How to get currently connected wifi SSID in c# using WMI or System.Net.NetworkInformation windows 10?

问题描述

我尝试了2种不同的方式

try{

ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\WMI", "SELECT * FROM MSNdis_80211_ServiceSetIdentifier");

    foreach (ManagementObject queryObj in searcher.Get())
    {
       Console.WriteLine("-----------------------------------");
       Console.WriteLine("MSNdis_80211_ServiceSetIdentifier instance");
       Console.WriteLine("-----------------------------------");

       if (queryObj["Ndis80211SsId"] == null)
       {
           //Console.WriteLine("Ndis80211SsId: {0}",queryObj["Ndis80211SsId"]);
       }
       else
       {
           Byte[] arrNdis80211SsId = (Byte[])
           (queryObj["Ndis80211SsId"]);
           foreach (Byte arrValue in arrNdis80211SsId)
           {
              //Console.WriteLine("Ndis80211SsId: {0}", arrValue);
           }
       }
    }

}catch(Exception ex){

}

第二种方式:我正在对wi-fi进行门控，但无法获取SSID

if (System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable()) {
    foreach (NetworkInterface ni in NetworkInterface.GetAllNetworkInterfaces()) {

   if (ni.NetworkInterfaceType == NetworkInterfaceType.Wireless80211 && ni.OperationalStatus== OperationalStatus.Up   ) {
       Network = "NETWORK ( N/A )";
           Wifi = "Wifi (" + ni.Name + ")";
        }
    }
}

您能不能请别人给我一个清晰的主意，让我知道如何获得连接的WiFi SSID.

Could you please someone give me clear idea how to get my connected wifi SSID.

推荐答案

    // Show SSID and Signal Strength
    private void showConnectedId() {
        System.Diagnostics.Process p = new System.Diagnostics.Process();
        p.StartInfo.FileName = "netsh.exe";
        p.StartInfo.Arguments = "wlan show interfaces";
        p.StartInfo.UseShellExecute = false;
        p.StartInfo.RedirectStandardOutput = true;
        p.Start();

        string s = p.StandardOutput.ReadToEnd();
        string s1 = s.Substring(s.IndexOf("SSID"));
        s1 = s1.Substring(s1.IndexOf(":"));
        s1 = s1.Substring(2, s1.IndexOf("\n")).Trim();

        string s2 = s.Substring(s.IndexOf("Signal"));
        s2 = s2.Substring(s2.IndexOf(":"));
        s2 = s2.Substring(2, s2.IndexOf("\n")).Trim();

        labelStatus.Text = "WIFI connected to " + s1 + "  " + s2;
        p.WaitForExit();
    }
