WMI Library and here is a VB.net example. It shouldn't be difficult to convert it to C#
WMI 库，这里是一个VB.net 示例。将其转换为 C# 应该不难

Checkout System.Managementand System.Management.ManagementClass. Both are used for accessing WMI, which is how to get the information in question.
签出System.Management和System.Management.ManagementClass。两者都用于访问WMI，即如何获取有问题的信息。
Edit:Updated with sample to access WMI from remote computer:
编辑：更新示例以从远程计算机访问 WMI：
ConnectionOptions options;
options = new ConnectionOptions();
options.Username = userID;
options.Password = password;
options.EnablePrivileges = true;
options.Impersonation = ImpersonationLevel.Impersonate;
ManagementScope scope;
scope = new ManagementScope("\\" + ipAddress + "\root\cimv2", options);
scope.Connect();
String queryString = "SELECT PercentProcessorTime, PercentInterruptTime, InterruptsPersec FROM Win32_PerfFormattedData_PerfOS_Processor";
ObjectQuery query;
query = new ObjectQuery(queryString);
ManagementObjectSearcher objOS = new ManagementObjectSearcher(scope, query);
DataTable dt = new DataTable();
dt.Columns.Add("PercentProcessorTime");
dt.Columns.Add("PercentInterruptTime");
dt.Columns.Add("InterruptsPersec");
foreach (ManagementObject MO in objOS.Get())
{
DataRow dr = dt.NewRow();
dr["PercentProcessorTime"] = MO["PercentProcessorTime"];
dr["PercentInterruptTime"] = MO["PercentInterruptTime"];
dr["InterruptsPersec"] = MO["InterruptsPersec"];
dt.Rows.Add(dr);
}
Note: userID, password, and ipAddress must all be defined to match your environment.
注意：用户 ID、密码和 ipAddress 都必须定义为与您的环境相匹配。

Here is an example of using it in like an about box. MSDN has the rest of the items you can all.
这是一个使用它的例子，就像一个关于框。MSDN 拥有您可以全部使用的其余项目。
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Management;
namespace About_box
{
public partial class About : Form
{
public About()
{
InitializeComponent();
FormLoad();
}
public void FormLoad()
{
SystemInfo si;
SystemInfo.GetSystemInfo(out si);
txtboxApplication.Text = si.AppName;
txtboxVersion.Text = si.AppVersion;
txtBoxComputerName.Text = si.MachineName;
txtBoxMemory.Text = Convert.ToString((si.TotalRam / 1073741824)
+ " GigaBytes");
txtBoxProcessor.Text = si.ProcessorName;
txtBoxOperatingSystem.Text = si.OperatingSystem;
txtBoxOSVersion.Text = si.OperatingSystemVersion;
txtBoxManufacturer.Text = si.Manufacturer;
txtBoxModel.Text = si.Model;
}
}
}
