可以通过 DriveInfo 类的 GetDrives 获取当前所有的驱动器磁盘 再通过 DriveType 枚举即可了解当前是否是可移动磁盘,如面代码 foreach (var...driveInfo in DriveInfo.GetDrives()) { if (driveInfo.DriveType == DriveType.Removable
File.Delete(fileNameMove);//尽量不要delete } } {//DriveInfo...DriveInfo[] drives = DriveInfo.GetDrives(); foreach (DriveInfo drive
DriveInfo是一个与驱动器有关的类。 Directory和File类 Directory和File是两个静态类,当只对文件对象执行一次或几次操作的时候很有用。...Path.VolumeSeparatorChar}"); Console.WriteLine($@"C:\Windows和System连接的结果是:{Path.Combine(@"C:\Windows", "System")}"); DriveInfo...类 DriveInfo类可以查看驱动器的相关信息。...DriveInfo c = new DriveInfo("C"); Console.WriteLine("查看驱动器信息\n"); Console.WriteLine($"可用空闲空间:{c.AvailableFreeSpace

但 DriveInfo 则无需这么做,它的属性每次都会读取文件系统最新的信息。 ...类(需要.NET 2.0) DriveInfo.GetDrives():获得计算机的所有逻辑驱动器,返回类型为DriveInfo[]; 问题11:如何获取指定驱动器的信息; ...解决方案: DriveInfo.Name:获取驱动器的名称(如C:/); DriveInfo.DriveType:获取驱动器的类型(如Fixed,CDRom,Removable,Network...等); DriveInfo.DriveFormat:获取驱动器的格式(如NTFS,FAT32,CDFS,UDF等); DriveInfo.IsReady:获取驱动器是否已准备好,比如...CD是否已放入CD驱动器,如果驱动器没有准备好,访问其信息会引发IOException类型异常; DriveInfo.AvailableFreeSpace:获取驱动器的可用空间; DriveInfo.TotalFreeSpace
通过查阅API,我们发现一个类: public sealed class DriveInfo : System.Runtime.Serialization.ISerializable//提供对有关驱动器的信息的访问...有一个方法: public static System.IO.DriveInfo[] GetDrives ();// 检索计算机上的所有逻辑驱动器的驱动器名称。...在项目中编写一个方法: public static void GetDrivers(){ var drives = DriveInfo.GetDrives(); foreach(var...System.Collections.Generic;//泛型集合的支持 修改方法如下: public static List GetDrivers() { var drives = DriveInfo.GetDrives
