ManagementObjectSearcher内存不足excepiton

在C＃.Net MVC2应用程序中，我们有一个简单的函数来获取处理器ID作为识别Web服务器的方案的一部分。相关部分是：ManagementObjectSearcher内存不足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(); 
       } 
      } 
     }

它一直在开发和运行cassini和IIS的Web服务器上工作正常。但是，在Server 2008机器上的最新安装中，它会在第一次调用时抛出一个Out of Memory Exception来获取处理器ID。任何建议可能的原因或更好的方式来实现上述。

非常感谢

显示异常的堆栈跟踪。 – 2010-12-07 14:48:24

我只是碰到了类似的问题，试图查询win32_service时。我去了Administrative Tools\Computer Management的WMI控制台。主屏幕显示Win32_Process的内存不足错误。我最终重新启动了WMI服务（“Windows Management Instrumentation”）并解决了这个问题。

在查询Win32_Service时，最近版本的WMI中存在已知的错误。例如，请参阅http://brooke.blogs.sqlsentry.net/2010/02/win32service-memory-leak.html。我不确定它适用于其他WMI类。 – 2011-01-07 19:06:01
