获取系统如cpu、内存、硬盘、网络等的实时情况

[wj0728]

要获取系统的这些信息，在不使用wmi服务的情况下进行操作，因为这个服务可能运行不正常，这样就会导致数据无法采集，除了性能计数器之外还可以用什么方式进行数据的采集，kernel32.dll这个类库运行是否基于windows的服务，知道的朋友麻烦指点一下，谢谢。
还有就是性能计数器的计数类型有哪些？
如"Processor", "% Processor Time", "_Total"
"Process", "Working Set", "_Total"

都可以通过performancecounter来获取

PerformanceCounter pfc = new PerformanceCounter("Processor", "% Processor Time", "_Total");
        PerformanceCounter networkReceivePerformance = new PerformanceCounter("Network Interface", "Bytes Received/sec", "Realtek PCIe FE Family Controller");
        PerformanceCounter networkSendPerformance = new PerformanceCounter("Network Interface", "Bytes Sent/sec", "Realtek PCIe FE Family Controller");
        PerformanceCounter diskPerformance = new PerformanceCounter("LogicalDisk", "% Free Space", "_Total");
        PerformanceCounter memoryPerformance = new PerformanceCounter("Memory", "Available MBytes");

C# code

[StructLayout(LayoutKind.Sequential)]
public struct SYSTEM_INFO
{
internal int dwOemId;

这种模式是基于什么的啊？

[bloodish]

[StructLayout(LayoutKind.Sequential)]
public struct SYSTEM_INFO
{
    internal int dwOemId;
    internal int dwPageSize;
    internal IntPtr lpMinimumApplicationAddress;
    internal IntPtr lpMaximumApplicationAddress;
    internal IntPtr dwActiveProcessorMask;
    internal int dwNumberOfProcessors;
    internal int dwProcessorType;
    internal int dwAllocationGranularity;
    internal short wProcessorLevel;
    internal short wProcessorRevision;
}

[DllImport("kernel32.dll", SetLastError=true)]
public static extern void GetSystemInfo(ref SYSTEM_INFO lpSystemInfo); 

[bloodish]

internal 请改成 public,写错了.

[bloodish]

其他一些信息

NetworkInterface.GetIsNetworkAvailable();
DriveInfo.GetDrives();

[porschev]

看看。。。。

[wuyq11]

DriveInfo[] drivers = DriveInfo.GetDrives();
PerformanceCounter cpuCounter;
PerformanceCounter ramCounter;
cpuCounter = new PerformanceCounter();
cpuCounter.CategoryName = "";

[DllImport("IpHlpApi.dll")]
extern static public uint GetIfTable(byte[] pIfTable, ref uint pdwSize, bool bOrder);来获取本机网络信息
