适合：上位机、工业PC、边缘网关
2.1 核心类（HardwareMonitor.cs）
csharp
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Management;
using System.Threading;
namespace HardwareMonitor
{
public class HardwareMonitor
{
private readonly Timer _timer;
private readonly int _intervalMs;
public delegate void HardwareDataHandler(HardwareData data);
public event HardwareDataHandler OnDataUpdated;
public HardwareMonitor(int intervalMs = 1000)
{
_intervalMs = intervalMs;
_timer = new Timer(Collect, null, Timeout.Infinite, Timeout.Infinite);
}
public void Start() => _timer.Change(0, _intervalMs);
public void Stop() => _timer.Change(Timeout.Infinite, Timeout.Infinite);
private void Collect(object state)
{
var data = new HardwareData
{
CpuUsage = GetCpuUsage(),
MemoryUsedMb = GetMemoryUsed(),
MemoryTotalMb = GetMemoryTotal(),
DiskUsage = GetDiskUsage(),
NetworkSentKBps = GetNetworkSent(),
NetworkReceivedKBps = GetNetworkReceived(),
Temperature = GetCpuTemperature()
};
OnDataUpdated?.Invoke(data);
}
#region CPU
private float GetCpuUsage()
{
using var cpu = new PerformanceCounter("Processor", "% Processor Time", "_Total");
cpu.NextValue();
Thread.Sleep(100);
return cpu.NextValue();
}
#endregion
#region Memory
private float GetMemoryUsed()
{
using var mem = new PerformanceCounter("Memory", "Committed Bytes");
return mem.NextValue() / 1024 / 1024;
}
private float GetMemoryTotal()
{
using var mem = new PerformanceCounter("Memory", "Commit Limit");
return mem.NextValue() / 1024 / 1024;
}
#endregion
#region Disk
private float GetDiskUsage()
{
using var disk = new PerformanceCounter("PhysicalDisk", "% Disk Time", "_Total");
disk.NextValue();
Thread.Sleep(100);
return disk.NextValue();
}
#endregion
#region Network
private float GetNetworkSent()
{
using var net = new PerformanceCounter("Network Interface", "Bytes Sent/sec", GetNetworkCard());
return net.NextValue() / 1024;
}
private float GetNetworkReceived()
{
using var net = new PerformanceCounter("Network Interface", "Bytes Received/sec", GetNetworkCard());
return net.NextValue() / 1024;
}
private string GetNetworkCard()
{
using var searcher = new ManagementObjectSearcher("SELECT Name FROM Win32_NetworkAdapter WHERE NetEnabled = true");
foreach (ManagementObject obj in searcher.Get())
return obj["Name"].ToString();
return "";
}
#endregion
#region Temperature (WMI)
private float GetCpuTemperature()
{
try
{
using var searcher = new ManagementObjectSearcher(@"root\WMI", "SELECT CurrentTemperature FROM MSAcpi_ThermalZoneTemperature");
foreach (ManagementObject obj in searcher.Get())
{
var temp = Convert.ToDouble(obj["CurrentTemperature"].ToString());
return (float)(temp / 10.0 - 273.15); // Kelvin → Celsius
}
}
catch { }
return 0;
}
#endregion
}
public class HardwareData
{
public float CpuUsage { get; set; }
public float MemoryUsedMb { get; set; }
public float MemoryTotalMb { get; set; }
public float DiskUsage { get; set; }
public float NetworkSentKBps { get; set; }
public float NetworkReceivedKBps { get; set; }
public float Temperature { get; set; }
public override string ToString()
{
return $"CPU:{CpuUsage:F1}% MEM:{MemoryUsedMb:F0}/{MemoryTotalMb:F0}MB DISK:{DiskUsage:F1}% TEMP:{Temperature:F1}℃";
}
}
}三、WPF 实时显示
3.1 MainWindow.xaml
xml
<Window x:Class="HardwareMonitor.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
Title="硬件实时监控" Height="320" Width="400">
<StackPanel Margin="20">
<TextBlock Text="CPU 使用率" FontWeight="Bold"/>
<ProgressBar x:Name="CpuBar" Height="20" Maximum="100"/>
<TextBlock x:Name="CpuText"/>
<TextBlock Text="内存使用" FontWeight="Bold" Margin="0,10,0,0"/>
<ProgressBar x:Name="MemBar" Height="20" Maximum="100"/>
<TextBlock x:Name="MemText"/>
<TextBlock Text="硬盘使用" FontWeight="Bold" Margin="0,10,0,0"/>
<ProgressBar x:Name="DiskBar" Height="20" Maximum="100"/>
<TextBlock Text="CPU 温度" FontWeight="Bold" Margin="0,10,0,0"/>
<TextBlock x:Name="TempText" FontSize="16" Foreground="Red"/>
</StackPanel>
</Window>3.2 MainWindow.xaml.cs
csharp
using System.Windows;
namespace HardwareMonitor
{
public partial class MainWindow : Window
{
private readonly HardwareMonitor _monitor;
public MainWindow()
{
InitializeComponent();
_monitor = new HardwareMonitor(1000);
_monitor.OnDataUpdated += UpdateUI;
_monitor.Start();
}
private void UpdateUI(HardwareData data)
{
Dispatcher.Invoke(() =>
{
CpuBar.Value = data.CpuUsage;
CpuText.Text = $"{data.CpuUsage:F1}%";
MemBar.Value = data.MemoryUsedMb / data.MemoryTotalMb * 100;
MemText.Text = $"{data.MemoryUsedMb:F0} MB / {data.MemoryTotalMb:F0} MB";
DiskBar.Value = data.DiskUsage;
TempText.Text = $"{data.Temperature:F1} ℃";
});
}
}
}参考代码 C# 实时查看 硬件使用率(CPU/内存/硬盘等) www.youwenfan.com/contentcsu/62418.html
四、远程设备监控
4.1 通过 WMI 监控远程 Windows 设备
csharp
public static float GetRemoteCpuUsage(string ip, string user, string pwd)
{
var options = new ConnectionOptions
{
Username = user,
Password = pwd,
Impersonation = ImpersonationLevel.Impersonate
};
var scope = new ManagementScope($"\\\\{ip}\\root\\cimv2", options);
scope.Connect();
using var searcher = new ManagementObjectSearcher(
scope, new ObjectQuery("SELECT LoadPercentage FROM Win32_Processor"));
foreach (ManagementObject obj in searcher.Get())
return Convert.ToSingle(obj["LoadPercentage"]);
return 0;
}五、Linux / ARM / 嵌入式（STM32 上位机）
csharp
// Linux
cat /proc/cpuinfo
cat /proc/meminfo
df -h
csharp
public static float GetLinuxCpuUsage()
{
var cpu = File.ReadAllText("/proc/stat").Split('\n')[0];
return ParseCpu(cpu);
}
