如何在 C# 中获取 CPU 速度和总物理内存？

我需要一种简单的方法来检查主机 PC 的 RAM 大小和 CPU 速度。我尝试了 WMI，但是我使用的代码

 private long getCPU()
 {
    ManagementClass mObject = new ManagementClass("Win32_Processor");
    mObject.Get();
    return (long)mObject.Properties["MaxClockSpeed"].Value;

 }

抛出空引用异常。此外，WMI 查询有点慢，我需要进行一些查询才能获得所有规格。有更好的办法吗？

I need a simple way of checking how much ram and fast the CPU of the host PC is. I tried WMI however the code I'm using

 private long getCPU()
 {
    ManagementClass mObject = new ManagementClass("Win32_Processor");
    mObject.Get();
    return (long)mObject.Properties["MaxClockSpeed"].Value;

 }

Throws a null reference exception. Furthermore, WMI queries are a bit slow and I need to make a few to get all the specs. Is there a better way?

http://dotnet-snippets.com/ dns/get-the-cpu-speed-in-mhz-SID575.aspx

using System.Management;

public uint CPUSpeed()
{
  ManagementObject Mo = new ManagementObject("Win32_Processor.DeviceID='CPU0'");
  uint sp = (uint)(Mo["CurrentClockSpeed"]);
  Mo.Dispose();
  return sp;
}

RAM可以在这个SO问题中找到：如何获得计算机拥有的 RAM 总量？

using System.Management;

public uint CPUSpeed()
{
  ManagementObject Mo = new ManagementObject("Win32_Processor.DeviceID='CPU0'");
  uint sp = (uint)(Mo["CurrentClockSpeed"]);
  Mo.Dispose();
  return sp;
}

RAM can be found in this SO question: How do you get total amount of RAM the computer has?

您应该在System.Diagnostics中使用PerformanceCounter类

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";
}

You should use PerformanceCounter class in System.Diagnostics

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";
}
