方法一：利用System.IO.DriveInfo.GetDrives方法來擷取

///           /// 擷取指定磁碟機的空間總大小(單位為B)         ///           ///  只需輸入代表磁碟機的字母即可 （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;         }        ///           /// 擷取指定磁碟機的剩餘空間總大小(單位為B)         ///           ///  只需輸入代表磁碟機的字母即可          ///            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")來擷取

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{// 磁碟名稱diskInfo["Name"] =disk["Name"].ToString();// 磁碟描述diskInfo["Description"]=disk["Description"].ToString();// 磁碟總容量，可用空間，已用空間if (System.Convert.ToInt64(disk["Size"]) > 0){long totalSpace = System.Convert.ToInt64(disk["Size"]) / MB;long freeSpace = System.Convert.ToInt64(disk["FreeSpace"]) / MB;long usedSpace = totalSpace - freeSpace;                        diskInfo["totalSpace"]=totalSpace.ToString();diskInfo["usedSpace"]=usedSpace.ToString();diskInfo["freeSpace"]=freeSpace.ToString();}diskInfoDic.Add(diskInfo);}catch(Exception ex){Throw ex;}}
