CPU内存占用

[jxq789478]

请问大家，如何用C#实现点击一个按钮后，把当前系统各个进程，CPU及内存使用情况输出到一个LISTBOX中；就像任务管理器一样？

[s8975565]

listBox1.Items.Clear();
            Process[] ps = Process.GetProcesses();
            for (int i = 0; i < ps.Length; i++)
            {
                this.listBox1.Items.Add(ps[i].ProcessName + "------>" + ps[i].Id);
            }
            this.listBox1.SelectedIndex = indexForUser;
            lblProcess.Text = "进程数:" + ps.Length;

为什么我用ramCounter = new PerformanceCounter("Memory", "Available MBytes");
取到的每个进程的内存值都是一样的啊？

[wuyq11]

PerformanceCounter cpuCounter;
PerformanceCounter ramCounter;
cpuCounter = new PerformanceCounter();
cpuCounter.CategoryName = "Processor";
cpuCounter.CounterName = "% Processor Time";
cpuCounter.InstanceName = "_Total";
ramCounter = new PerformanceCounter("Memory", "Available MBytes");
public string getCurrentCpuUsage(){
cpuCounter.NextValue()+"%";
}

public string getAvailableRAM(){
ramCounter.NextValue()+"MB";
}

在 process 里面找找相关方法
