在C#中怎样判断驱动器是软驱还是光驱或硬盘

[youlong34]

在C#中用Directory.GetLogicalDrives()能得到盘符，可是怎样才能区分每个盘符对应的是软驱还是光驱或硬盘呢？请多指教！！！

using System.Management;

const int Removable = 2;
const int LocalDisk = 3;
const int Network = 4;
const int CD = 5;

ManagementObjectCollection queryCollection = getDrives();
foreach ( ManagementObject mo in queryCollection)
{
switch (int.Parse( mo["DriveType"].ToString()))
{
case Removable: //removable drives
imageIndex = (int)FileImages.FLOPPYDISK;
break;
case LocalDisk: //Local drives
imageIndex = (int)FileImages.LOCALDISK;
break;
case CD: //CD rom drives
imageIndex = (int)FileImages.CDDISK;
break;
case Network: //Network drives
imageIndex = (int)FileImages.Network;
break;
default: //defalut to folder
imageIndex = (int)FileImages.FILE_IMAGE_DEFAULT;
break;
}
//
// show the drive in the ListView
//
listView.Items.Add( mo["Name"].ToString() , imageIndex );
}

/// <summary>
/// 获取磁盘上的目录
/// </summary>
/// <returns></returns>
public ManagementObjectCollection getDrives()
{
//get drive collection
ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * From Win32_LogicalDisk ");
ManagementObjectCollection queryCollection = query.Get();

return queryCollection;
}
