如何在 .NET 中阅读“% Time in GC”

Question

我尝试通过

读取内存性能计数器'% Time in GC'

 Process p = Process.GetCurrentProcess();
 PerformanceCounter gcTimeCounter = new PerformanceCounter("Memory", "% Time in GC");

但这会引发 InvalidOperation 类型的异常。如何读取这个参数？

Answer 1

该计数器包含在 .NET CLR 内存 类别中，因此：

PerformanceCounter gcTimeCounter = 
   new PerformanceCounter(".NET CLR Memory", "% Time in GC");
