c# - 如何在 Windows 7 中查找 WLAN 卡

Question

下面的代码在 Win XP 中工作正常，直到确定 WLAN 卡，但在 Windows 7 中 wmiObjects 计数为零。

有没有人知道让它在 Windows 7 中工作？

//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);
}

Answer 2

MSDis802_11_Configuration 仅在 WinXP 和 Win2003 中受支持。

尝试改用 Win32_NetworkAdapter。
