使用C＃返回CPU使用率在WMI [英] Returning CPU usage in WMI using C#

问题描述

要通过使用WMI返回的CPU使用率，我从Win32_PerfFormattedData_PerfOS_Processor返回PercentProcessorTime？如果不是这样，我应该朝哪个班？谢谢

解决方案

  ManagementObjectSearcher搜索=新ManagementObjectSearcher（SELECT * FROM Win32_PerfFormattedData_PerfOS_Processor）; 
的foreach（在searcher.Get的ManagementObject OBJ（））
 {
变种使用的obj = [PercentProcessorTime]; 
变数名称的obj = [名称]; 
 Console.WriteLine（名+：+使用）; 
} 
  

和对LINQ爱好者

  ManagementObjectSearcher搜索=新ManagementObjectSearcher（SELECT * FROM Win32_PerfFormattedData_PerfOS_Processor）; 
 VAR cpuTimes = searcher.Get（）
 .Cast<的ManagementObject>（）
。选择（MO =>新建
 {
名称= MO [名称]，
用法= MO [PercentProcessorTime] 
} 
）
 .ToArray（）; 
  

To return the CPU usage by using WMI, do I return the PercentProcessorTime from Win32_PerfFormattedData_PerfOS_Processor? If not, which class should I look towards? Thanks.

解决方案

ManagementObjectSearcher searcher = new ManagementObjectSearcher("select * from Win32_PerfFormattedData_PerfOS_Processor");
foreach (ManagementObject obj in searcher.Get())
{
    var usage = obj["PercentProcessorTime"];
    var name = obj["Name"];
    Console.WriteLine(name +" : " + usage);
}

And for Linq lovers

ManagementObjectSearcher searcher = new ManagementObjectSearcher("select * from Win32_PerfFormattedData_PerfOS_Processor");
var cpuTimes = searcher.Get()
    .Cast<ManagementObject>()
    .Select(mo => new
        {
            Name = mo["Name"],
            Usage = mo["PercentProcessorTime"]
        }
    )
    .ToArray();
