怎样获得WIFI的信号强度

Answer 1

Answer 2

WMI query for MSNdis_80211_ReceivedSignalStrengthusing System;
using System.Management;
class App
{
public static void Main()
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher(
@"root\WMI",
"select Ndis80211ReceivedSignalStrength from
MSNdis_80211_ReceivedSignalStrength where active=true");
foreach (ManagementObject mo in searcher.Get())
{
Console.WriteLine("{0}",mo["Ndis80211ReceivedSignalStrength"]);
}
}
}
