C# to achieve the disk space size

This article describes the method of C# to obtain disk space size. Share it for your reference. The specific implementation method is as follows:

Method 1: Use methods to obtain

Copy the codeThe code is as follows:

///
/// Get the total space size of the specified drive (unit is B)
///
/// Just enter the letter representing the drive (caps)
///
public static long GetHardDiskSpace(string str_HardDiskName)
{
    long totalSize= new long();
    str_HardDiskName=str_HardDiskName +":\\";
    [] drives = ();
    foreach ( drive in drives)
    {
if ( == str_HardDiskName)
{
     totalSize = / (1024 * 1024 * 1024);
}
    }
    return totalSize;
}

///
/// Get the total remaining space size of the specified drive (unit is B)
///
/// Just enter the letters representing the drive
///
public static long GetHardDiskFreeSpace(string str_HardDiskName)
{
    long freeSpace = new long();
    str_HardDiskName = str_HardDiskName + ":\\";
    [] drives = ();
    foreach ( drive in drives)
    {
if ( == str_HardDiskName)
{
     freeSpace = / (1024 * 1024 * 1024);
}
    }
    return freeSpace;
}

Method 2: Use ManagementClass("Win32_LogicalDisk") to obtain

Copy the codeThe code is as follows:

List<Dictionary<string, string>> diskInfoDic = new List<Dictionary<string, string>>();

ManagementClass diskClass = new ManagementClass("Win32_LogicalDisk");

ManagementObjectCollection disks = ();

foreach(ManagementObject disk in disks)

{

 Dictionary<string, string> diskInfo = new Dictionary<string, string>();

 try

 {
// Disk name

     diskInfo["Name"] =disk["Name"].ToString();
// Disk description

     diskInfo["Description"]=disk["Description"].ToString();
// Total disk capacity, available space, used space

     if (.ToInt64(disk["Size"]) > 0)

     {

  long totalSpace = .ToInt64(disk["Size"]) / MB;

  long freeSpace = .ToInt64(disk["FreeSpace"]) / MB;

  long usedSpace = totalSpace - freeSpace;

       diskInfo["totalSpace"]=();

  diskInfo["usedSpace"]=();

  diskInfo["freeSpace"]=();

     }

     (diskInfo);

 }

 catch(Exception ex)

 {

     Throw ex;

 }

}
