System.Management.ManagementException [英] System.Management.ManagementException

问题描述

我正在运行以下代码：

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

在某些机器上还可以，在某些机器上我得到以下错误：

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

System.Management.ManagementException：找不到

System.Management.ManagementException: Not found

调用堆栈：

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()

知道为什么吗？

推荐答案

System.Management 命名空间取决于 WMI（Windows管理规范）服务。

我怀疑在抛出该异常的系统上尚未启动WMI服务。

I suspect that the WMI service has not been started on the systems that are throwing that exception.

出于故障排除的目的，您可以使用管理工具→服务实用程序来验证。

For troubleshooting purposes, you can verify that using the Administrative Tools → Services utility.

如果确实如此，则可以将代码包装为 try - catch 块并使用 ServiceController 类启动和停止适当的服务。

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.
