C# 獲取磁盤空間大小的方法

方法一：利用System.IO.DriveInfo.GetDrives方法來獲取

///           /// 獲取指定驅動器的空間總大小(單位為B)         ///           ///  只需輸入代表驅動器的字母即可 （大寫）         ///            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 / (1024 * 1024 * 1024);                 }             }             return totalSize;         }        ///           /// 獲取指定驅動器的剩余空間總大小(單位為B)         ///           ///  只需輸入代表驅動器的字母即可          ///            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 / (1024 * 1024 * 1024);                 }             }             return freeSpace;         }

方法二：利用ManagementClass("Win32_LogicalDisk")來獲取

List<Dictionary<string, string>> diskInfoDic = new List<Dictionary<string, string>>();ManagementClass diskClass = new ManagementClass("Win32_LogicalDisk");ManagementObjectCollection disks = diskClass.GetInstances();foreach(ManagementObject disk in disks){Dictionary<string, string> diskInfo = new Dictionary<string, string>();try{// 磁盤名稱diskInfo["Name"] =disk["Name"].ToString();// 磁盤描述diskInfo["Descr
