Using WMI to get information about your hard disk

Hard disk first, what is WMI?
WMI (Windows Management Schema: Windows Management Instrumentation) is a Microsoft web-based Enterprise Management (WBEM) and Desktop Management Task Force (DMTF) The realization of industrial standard. is a standards-based system Management development interface that is used to control the management of computers. It provides an easy way to manage and control system resources.
If you want to know more about him, you can refer to the micorosft Platform SDK. In this we just implement a simple function through it to get information about the hard disk in our system.
We need to implement the class provided in the. NET Framwork with the System.Management namespace.
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]);
}
}
}
}
}



The. NET Framework SDK has its own help with code to get the size of a logical hard disk:
[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
