這篇文章主要介紹了C#實現獲取磁盤空間大小的方法,分別基于System.IO.DriveInfo.GetDrives方法與ManagementClass("Win32_LogicalDisk")來實現這一功能,是非常實用的技巧,需要的朋友可以參考下

本文實例講述了C#實現獲取磁盤空間大小的方法。分享給大家供大家參考。具體實現方法如下：

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

復制代碼代碼如下:

///
/// 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

復制代碼代碼如下:

		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["Description"]=disk["Description"].ToString();
		     // 磁盤總容量，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;
		 }
		}
