c# - 获取wifi信号强度 | wifi信号强度

有没有办法在C#中获得wifi信号强度？目前我正在通过相同

Process proc = new Process();
proc.StartInfo.CreateNoWindow = true;
proc.StartInfo.FileName = "netsh";
proc.StartInfo.Arguments = "wlan show interfaces";
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.UseShellExecute = false;
proc.Start();

然后通过读取输出获得wifi信号强度。有没有更好的办法？最好使用API

最佳答案

为什么不使用WMI查询以一种干净的方式获取它？

private double RetrieveSignalString()
{
   double theSignalStrength = 0;
   ConnectionOptions theConnectionOptions = new ConnectionOptions();
   ManagementScope theManagementScope = new ManagementScope("root\\wmi");
   ObjectQuery theObjectQuery = new ObjectQuery("SELECT * FROM MSNdis_80211_ReceivedSignalStrength WHERE active=true");
   ManagementObjectSearcher theQuery = new ManagementObjectSearcher(theManagementScope, theObjectQuery);

   try
   {

      //ManagementObjectCollection theResults = theQuery.Get();
      foreach(ManagementObject currentObject in theQuery.Get())
      {
         theSignalStrength = theSignalStrength + Convert.ToDouble(currentObject["Ndis80211ReceivedSignalStrength"]);
      }
   }
   catch (Exception e)
   {
      //handle
   }
   return Convert.ToDouble(theSignalStrength);
}
