C#实现获取磁盘空间大小的方法

本文实例讲述了C#实现获取磁盘空间大小的方法。分享给大家供大家参考。具体实现方法如下：

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

复制代码代码如下:

///   

/// 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

复制代码代码如下:

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;

 }

}
