Use WMI to obtain the drive list

In yesterday's Essay: two hard disks and files related tips use APIs for obtaining the list of Hard Disk Partitions. As a reminder of the source of inspiration, WMI is used for implementation, now we have succeeded. Thanks for the ideas provided by the inspiration source.

The following is the sample code:

You must first reference System. Management. dll,

Using System. Management;

SelectQuery query =
New SelectQuery ("SELECT * FROM Win32_LogicalDisk WHERE DriveType = 3 ");

ManagementObjectSearcher searcher =
New ManagementObjectSearcher (query );

Foreach (ManagementBaseObject envVar in searcher. Get ())
{
This. listBox1.Items. Add (envVar ["Name"]. ToString ());
}

If the value of DriveType in the query statement is 2, the drive is obtained. If the value is 5, the drive is obtained.
