c# - 删除性能计数器类别失败

Question

我有这个简单的代码:

public void CreateCounters() {
    if (PerformanceCounterCategory.Exists(_categoryName)) {
        PerformanceCounterCategory.Delete(_categoryName);
    }

    // create logic…
}

在我的机器上工作。我在我的服务器上运行它，得到以下堆栈跟踪:

System has detected a fatal error. EXITING... 
NativeErrorCode: 1010 
ErrorCode: -2147467259 
Message: The configuration registry key is invalid 
TargetSite: Void RegisterFiles(System.String, Boolean) 
HelpLink:  
Source: System 
Stack Trace:

 at myApp.Common.Utils.PerformanceCounters.myAppPerformanceCounterReporter.get_Instance() 
 at myApp.Program.Main(String[] args) 

该类别存在于服务器上，我可以在 perfmon GUI 中看到它。

好的，这是性能计数器机制中的一些错误，应该通过以下脚本修复:

cd %systemroot%\system32
lodctr /R
