有没有办法在C#中获取wifi信号强度?目前我也得到了同样的结果
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();
然后我通过读取输出来获取 wifi 信号强度。有没有更好的办法?最好使用 API
为什么不使用 WMI 查询以干净的方式获取它?
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);
}
