方法一：利用System.IO.DriveInfo.GetDrives方法来获取

		/// 获取指定驱动器的空间总大小(单位为B)//////  只需输入代表驱动器的字母即可 （大写）///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;}        ////// 获取指定驱动器的剩余空间总大小(单位为B)//////  只需输入代表驱动器的字母即可///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”)来获取

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{// 磁盘名称diskInfo["Name"] =disk["Name"].ToString();// 磁盘描述diskInfo["Description"]=disk["Description"].ToString();// 磁盘总容量，可用空间，已用空间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;}
}
