這篇文章主要介紹了C#實現(xiàn)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(xiàn)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(xiàn)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(xiàn)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(qū)動器的空間總大小(單位為B)
///
/// 只需輸入代表驅(qū)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(qū)動器的剩余空間總大小(單位為B)
///
/// 只需輸入代表驅(qū)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?cè)萘?，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;

 }

}
