cscの作法 その570

概要

cscの作法、調べてみた。
ドライブを表示するアプリ見つけたので、やってみた。

サンプルコード

using System;
using System.Linq;
using System.Management;
using System.Collections.Generic;
using System.Windows;
using System.IO;

public class USBUtil {
	public static bool EsUnidadExterna(string elPath) {
		var disco = Path.GetPathRoot(Path.GetFullPath(elPath));
		var usbD = GetUsbDriveLetters();
		return usbD.Contains(disco);
	}
	public static List<string> GetUsbDriveLetters() {
		var usbDrivesLetters = from drive in new ManagementObjectSearcher("select * from Win32_DiskDrive WHERE MediaType like '%External%' OR InterfaceType='USB'").Get().Cast<ManagementObject>()
							   from o in drive.GetRelated("Win32_DiskPartition").Cast<ManagementObject>()
							   from i in o.GetRelated("Win32_LogicalDisk").Cast<ManagementObject>()
							   select string.Format("{0}\\", i["Name"]);
		return usbDrivesLetters.ToList();
	}
}
class Program {
	static void Main(string[] args) {
		foreach (var dr in DriveInfo.GetDrives())
			Console.WriteLine("Unidad: {0}, tipo: {1}, label: {2}, fmt: {3}", dr.Name, dr.DriveType, dr.VolumeLabel, dr.DriveFormat);
		Console.WriteLine();
		var usb = USBUtil.GetUsbDriveLetters();
		foreach (var s in usb)
			Console.WriteLine("{0}", s);
		Console.WriteLine();
	}
}

実行結果

>usbu0
Unidad: C:\, tipo: Fixed, label: Windows, fmt: NTFS
Unidad: D:\, tipo: Removable, label: , fmt: FAT32

D:\

以上。
