C# 如何在Windows 7中查找WLAN卡

以下代码在Win XP中正常工作，直到确定WLAN卡，但在Windows 7中wmiObjects计数为零

有人知道如何让它在Windows7中工作吗

//Use MSDis802_11_Configuration to determine if this nic is in the list of wlan cards

try
{
  ObjectQuery query = new ObjectQuery("SELECT * FROM MSNdis_80211_Configuration");
  ManagementObjectCollection wmiObjects = new ManagementObjectSearcher(new ManagementScope(@"\\.\root\wmi"), query).Get();

  //Go through the result, if an instance matches this card, determine that it is wireless
  foreach (ManagementObject obj in wmiObjects)
  {
    string instanceName = obj.GetPropertyValue("InstanceName") as String;

    if (String.Compare(instanceName, _name) == 0)
    {
      isWireless = true;
      break;
    }
  }

  Log.DoLog("Items found: " + wmiObjects.Count);
}

您可以在codeplex上使用托管api。MSDis802\u 11\u配置仅在WinXP和Win2003中受支持

尝试改用Win32_NetworkAdapter
