C#获取远程主机CPU占用率，内存占用率，磁盘占用率代码

你可以使用 `PerformanceCounter` 类来获取远程主机的 CPU 占用率，内存占用率和磁盘占用率。

下面是获取远程主机 CPU 占用率的示例代码：

string machineName = "RemoteMachineName";
PerformanceCounter cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total", machineName);

float cpuUsage = cpuCounter.NextValue();
System.Threading.Thread.Sleep(1000);
cpuUsage = cpuCounter.NextValue();
Console.WriteLine("CPU Usage: {0}%", cpuUsage);

下面是获取远程主机内存占用率的示例代码：

string machineName = "RemoteMachineName";
PerformanceCounter memCounter = new PerformanceCounter("Memory", "Available MBytes", machineName);

float memUsage = memCounter.NextValue();
Console.WriteLine("Memory Usage: {0} MB", memUsage);

下面是获取远程主机磁盘占用率的示例代码：

string machineName = "RemoteMachineName";
PerformanceCounter diskCounter = new PerformanceCounter("LogicalDisk", "% Free Space", "C:", machineName);

float diskUsage = diskCounter.NextValue();
Console.WriteLine("Disk Usage: {0}%", 100 - diskUsage);

请注意，上述示例代码只是演示如何获取远程主机的 CPU 占用率、内存占用率和磁盘占用率。在实际应用中，你需要根据需要进行适当的修改。同时，你也需要确保你有足够的权限来访问远程主机的性能计数器。
