我正在下面code

System.Management.ManagementClass wmiNetAdapterConfiguration = new System.Management.ManagementClass("Win32_NetworkAdapterConfiguration"); System.Management.ManagementObjectCollection wmiNetAdapters = wmiNetAdapterConfiguration.GetInstances(); Log.logInfo("Net adapters:" + wmiNetAdapters.get_Count());

和在一些机器上它是好的，并且在一些我收到以下错误：

and on some machines it is ok , and on some i am getting following error :

System.Management.ManagementException: Not found at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode) at System.Management.ManagementScope.InitializeGuts(Object o) at System.Management.ManagementScope.Initialize() at System.Management.ManagementObject.Initialize(Boolean getObject) at System.Management.ManagementClass.GetInstances(EnumerationOptions options) at System.Management.ManagementClass.GetInstances()

任何想法，为什么？

Any idea why ?

推荐答案

由提供的功能 System.Management 命名空间是依赖于的 WMI（Windows管理规范）服务。

我怀疑是WMI服务尚未开始被抛出该异常系统。 为了排除故障，您可以验证使用的管理工具 - >服务工具 如果这原来是这样，你可以用在code在尝试 - 抓块使用ServiceController类启动和停止相应的服务。

I suspect that the WMI service has not been started on the systems that are throwing that exception. For troubleshooting purposes, you can verify that using the Administrative Tools -> Services utility. If this turns out to be the case, you can wrap the code in a try-catch block and use the ServiceController class to start and stop the appropriate service.
