使用WMI获得硬盘的信息

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.Management

       

// 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
