GetLogicalDrives()可以实现。具体代码:

[StructLayout(LayoutKind.Sequential)]
		public struct SHFILEINFO 
		{
			public IntPtr hIcon; 
			public int iIcon;
			public int dwAttributes; 
			public string szDisplayName; 
			public string szTypeName; 
		}

		[DllImport("shell32")]
		private static extern int SHGetFileInfo(string pszPath,int dwFileAttributes,ref SHFILEINFO psfi,int cbFileInfo,int uFlags);
		const int SHGFI_ICON = 0x0100;
		const int SHGFI_LARGEICON = 0x0000; 

		static string[] drives;
		ImageList img=new ImageList();

		private void Form1_Load(object sender, System.EventArgs e)
		{
			this.listView1.LargeImageList=img;
			this.listView1.SmallImageList=img;
			this.listView1.StateImageList=img;

			drives=Environment.GetLogicalDrives();
			for(int i=0;i<drives.Length;i++)
			{
				string str_temp=drives[i];
				this.listView1.Items.Add(str_temp);
				this.listView1.Items[i].ImageIndex=i;
			}
			for(int i=0;i<drives.Length;i++)
			{
				SHFILEINFO FileInfo=new SHFILEINFO();
				SHGetFileInfo(drives[i],0,ref FileInfo,Marshal.SizeOf(FileInfo),SHGFI_ICON | SHGFI_LARGEICON);

				Icon myIcon;
				myIcon=Icon.FromHandle(FileInfo.hIcon);
				img.Images.Add(myIcon); 
			}
		}
