How can I get total size of File in MB or KB etc... ?

Question

Hello Everyone,

 

I have list of items to bind listview wpf. Inside list items there is  FileSize = FormatBytes(x.fsize) I want to get total size of FileSize. How can I do that ?

 

  

public UC_ArcMgmt()
       {
           InitializeComponent();
           DMSBusinessLayer service = new DMSBusinessLayer();
           var data = service.GetArchivedList().SelectMany((x) => new[] { new { Fullname = x.Fullname, Id = x.Id, ArchievedName = x.ArchievedName, UpdatedDate = x.UpdatedDate, FileSize = FormatBytes(x.fsize), docCount = x.docCount } }).Distinct()
GroupBy((x) => x.ArchievedName);
           List<Tble_Documents> objTble_Documents = new List<Tble_Documents>();
           foreach (var x in data)
           {
               objTble_Documents = x.AsEnumerable().Select(m => new Tble_Documents()
                   {
                       Fullname = m.Fullname,
                       Id = m.Id,
                       ArchievedName = m.ArchievedName,
                       UpdatedDate = m.UpdatedDate,
                       FilePath = m.FileSize,
                       docCount = m.docCount
                   }).ToList();
           }
           listView1.ItemsSource = objTble_Documents;
       }

       private static string FormatBytes(long bytes)
       {
           string[] Suffix = { "B", "KB", "MB", "GB", "TB" };
           int i;
           double dblSByte = bytes;
           for (i = 0; i < Suffix.Length && bytes >= 1024; i++, bytes /= 1024)
           {
               dblSByte = bytes / 1024.0;
           }
           return String.Format("{0:0.##} {1}", dblSByte, Suffix[i]);
       }
