问题描述

HI朋友，

i我正在使用下面提到的功能是我计算的整体CPU使用率

但是我希望功能在i中我会传递进程名称作为参数并获取cpu使用率，Ram使用率和胎面。

请帮助完成这项任务

HI Friends,
i am using function below mention is which i have calculate overall CPU usage

but i want function in i will pass process name as parameter and get cpu usage, Ram usage and tread.

please help for this task

private void CalcCpu()
{
    // refresh delay 1.5 seconds
    int RefreshInterval = 1500;
    // keeps the previous usage value.
    long OldRawUsageValue = GetCurrentUsageValue();
    // keeps the current usage value.
    long NewRawUsageValue;
    // holds the cpu usage in a friendly reading way.
    string CpuUsage;

    Thread.Sleep(RefreshInterval);

    while (KeepCalculation)
    {
        NewRawUsageValue = GetCurrentUsageValue();
        CpuUsage = ((int)((NewRawUsageValue - OldRawUsageValue) /
                                  RefreshInterval)).ToString() + "%";
        Thread.Sleep(RefreshInterval);
        OldRawUsageValue = NewRawUsageValue;
    }
}

推荐答案

Imports System.Diagnostics

If PerformanceCounterCategory.InstanceExists( applicationInstanceName , "% Processor Time") Then
  ' Code to use that performance counter....

End If

我建议你不要使用Thread.Sleep虽然...

I would recommend you do NOT use Thread.Sleep though...
