ManagementObjectSearcher內存不足excepiton

在C＃.Net MVC2應用程序中，我們有一個簡單的函數來獲取處理器ID作爲識別Web服務器的方案的一部分。相關部分是：ManagementObjectSearcher內存不足excepiton

using (ManagementObjectSearcher searcher = new ManagementObjectSearcher("select ProcessorId from Win32_Processor")) 
     { 
      foreach (ManagementObject share in searcher.Get()) 
      { 
       foreach (PropertyData PC in share.Properties) 
       { 
        return PC.Value.ToString(); 
       } 
      } 
     }

它一直在開發和運行cassini和IIS的Web服務器上工作正常。但是，在Server 2008機器上的最新安裝中，它會在第一次調用時拋出一個Out of Memory Exception來獲取處理器ID。任何建議可能的原因或更好的方式來實現上述。

非常感謝

顯示異常的堆棧跟蹤。 – 2010-12-07 14:48:24

我只是碰到了類似的問題，試圖查詢win32_service時。我去了Administrative Tools\Computer Management的WMI控制檯。主屏幕顯示Win32_Process的內存不足錯誤。我最終重新啓動了WMI服務（「Windows Management Instrumentation」）並解決了這個問題。

在查詢Win32_Service時，最近版本的WMI中存在已知的錯誤。例如，請參閱http://brooke.blogs.sqlsentry.net/2010/02/win32service-memory-leak.html。我不確定它適用於其他WMI類。 – 2011-01-07 19:06:01
