  首先,什么是WMI?

     WMI（Windows管理架构：Windows Management Instrumentation）是Microsoft基于Web的企业管理（WBEM）和 Desktop Management Task Force(DMTF)工业标准的实现. 就是一种基于标准的系统管理的开发接口,这组接口用来控制管理计算机. 它提供了一种简单的方法来管理和控制系统资源.

    如果你想深入了解他,可以参考Micorosft Platform SDK . 在这我们只是通过它实现一个简单的功能,  得到我们系统中硬盘的相关信息.

    我们需要使用.net Framwork里面System.Management名字空间下提供的类来实现.

  using System;
  using System.Management;
  using System.Collections;
  using System.Collections.Specialized;
  namespace ACE_Console
  {
       class ACE_Console
   {
          [STAThread]
          static void Main(string[] args)
           {
          StringCollection propNames = new StringCollection();
         ManagementClass driveClass = new ManagementClass("Win32_DiskDrive");
         PropertyDataCollection  props = driveClass.Properties;
          foreach (PropertyData driveProperty in props) 
           {
        propNames.Add(driveProperty.Name);
                     }

      int idx = 0;
       ManagementObjectCollection drives = driveClass.GetInstances();
        foreach (ManagementObject drv in drives) 
        { 
        Console.WriteLine(" Drive({0}) Properties ", idx+1);
          foreach (string strProp in propNames)
          {
           Console.WriteLine("Property: {0}, Value: {1}", strProp, drv[strProp]);
                            }
                     }
              }
       }
  }    
 
  .net Framework SDK自带的帮助里有获得逻辑硬盘大小的代码：
  [C#]

  using System;

  using System.Management;       

   // This example demonstrates getting information about a class using the ManagementClass object

  class Sample_ManagementClass

  {

       public static int Main(string[] args)

  {

   ManagementClass diskClass = new ManagementClass("Win32_LogicalDisk");

    diskClass.Get();

   Console.WriteLine("Logical Disk class has " + diskClass.Properties.Count + " properties");

   return 0;

       }

  }                                

  [vb]
  Imports System

  Imports System.Managemen
       
  // This example demonstrates getting information about a class using the ManagementClass

  Class Sample_ManagementClass

  Overloads Public Shared Function Main(args() As String) As Integer

  Dim diskClass As New ManagementClass("Win32_LogicalDisk")

  diskClass.Get()

  Console.WriteLine(("Logical Disk class has " & diskClass.Properties.Count.ToString() & " properties"))

  Return 0

  End Function

  End Class
