PerformanceCounterCategory 到字符串值

我正在尝试检索 ReadyBoost 缓存的值我编写了以下代码，但它说该值不存在

System.Diagnostics.PerformanceCounterCategory pc;
            pc = new System.Diagnostics.PerformanceCounterCategory("ReadyBoost Cache");
            pc.GetCounters("Bytes cached");
            MessageBox.Show(Convert.ToString(pc));

拼写正确，我可以看到此代码后面的对象

I am trying to retrieve the value of my readyboost cache I wrote the following code but it says the value does not exist

System.Diagnostics.PerformanceCounterCategory pc;
            pc = new System.Diagnostics.PerformanceCounterCategory("ReadyBoost Cache");
            pc.GetCounters("Bytes cached");
            MessageBox.Show(Convert.ToString(pc));

GetCounters的参数应该是性能计数器的实例名称。更改您的代码如下：

    System.Diagnostics.PerformanceCounterCategory pc;
    pc = new System.Diagnostics.PerformanceCounterCategory("ReadyBoost Cache");
    foreach (PerformanceCounter counter in pc.GetCounters())
    {
        if (counter.CounterName == "Bytes cached")
        {
            //to do
        }
    }

the parameter of GetCounters should be the instance name of the performance Counter. change your code as follows:

    System.Diagnostics.PerformanceCounterCategory pc;
    pc = new System.Diagnostics.PerformanceCounterCategory("ReadyBoost Cache");
    foreach (PerformanceCounter counter in pc.GetCounters())
    {
        if (counter.CounterName == "Bytes cached")
        {
            //to do
        }
    }
