获取系统如cpu、内存、硬盘、网络等的实时情况

Question

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"

Answer 1

[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); 

Answer 2

internal 请改成 public,写错了.

Answer 3

其他一些信息
NetworkInterface.GetIsNetworkAvailable();
DriveInfo.GetDrives();

Answer 4

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

string   strResult;   ManagementClass   diskClass   =   new   ManagementClass( "Win32_LogicalDisk ");   ManagementObjectCollection   disks;   
disks   =   diskClass.GetInstances();   
foreach(   ManagementObject   disk   in   disks)   
{   
strResult   =   " ";   strResult   +=   "设备ID: "   +   disk[ "DeviceID "];   strResult   +=   "磁盘名称: "   +   disk[ "Name "];   strResult   +=   "磁盘卷标: "   +   disk[ "VolumeName "];   if(   disk[ "FileSystem "].ToString()   !=   " "   )   
{   
strResult   +=   "文件系统: "   +   disk[ "FileSystem "];   strResult   +=   "磁盘描述: "   +   disk[ "Description "];   if(   System.Convert.ToInt64(disk[ "Size "])   >   0   )   
{   
strResult   +=   "磁盘大小: "   +   System.Convert.ToInt64(disk[ "Size "].ToString());   
}   
strResult   +=   "磁盘类型: "   +   System.Convert.ToInt16(disk[ "DriveType "].ToString());   
}   
Response.Write(strResult);   
}

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");
