本章讲述：获取指定路径盘符的总容量和剩余容量；

获取总容量

    /// 获取指定驱动器的空间总大小(单位为B)
    /// </summary>
    /// <param name="str_HardDiskName">只需输入代表驱动器的字母即可 </param>
    /// <returns> </returns>
    public static long GetHardDiskSpace(string str_HardDiskName)
    {
        long totalSize = new long();
        str_HardDiskName = str_HardDiskName + ":\\";
        System.IO.DriveInfo[] drives = System.IO.DriveInfo.GetDrives();
        foreach (System.IO.DriveInfo drive in drives)
        {
            if (drive.Name == str_HardDiskName)
            {
                totalSize = drive.TotalSize;
            }
        }
        return totalSize;
    }

获取剩余容量

    /// <summary>
    /// 获取指定驱动器的剩余空间总大小(单位为B)
    /// </summary>
    /// <param name="str_HardDiskName">只需输入代表驱动器的字母即可 </param>
    /// <returns> </returns>
    public static long GetHardDiskFreeSpace(string str_HardDiskName)
    {
        long freeSpace = new long();
        str_HardDiskName = str_HardDiskName + ":\\";
        System.IO.DriveInfo[] drives = System.IO.DriveInfo.GetDrives();
        foreach (System.IO.DriveInfo drive in drives)
        {
            if (drive.Name == str_HardDiskName)
            {
                freeSpace = drive.TotalFreeSpace;
            }
        }
        return freeSpace;

    }
