Get Media Item File Size in Sitecore

10 comments
I recently got into a situation where I have to return the size of selected pdf file. In Sitecore using Sitecore.Data.Items.MediaItem class, we can access file size, extension, mime type etc of selected media item.

I have written a function GetSitecoreMediaItemSizeInBytes(string itemId) which takes item id of media item and return the size of media item in bytes.
public long GetSitecoreMediaItemSizeInBytes(string itemId)
        {
            long mediaItemSize = 0;
            if (Sitecore.Data.ID.IsID(itemId))
            {
                Item sitecoreItem = Sitecore.Context.Database.GetItem(Sitecore.Data.ID.Parse(itemId));
                if (sitecoreItem != null)
                {
                    MediaItem mediaItem = new MediaItem(sitecoreItem);
                    mediaItemSize = mediaItem.Size;                   
                }
                else
                {
                    Sitecore.Diagnostics.Log.Error("Could not find given sitecore media item with id '" + itemId + "' ", this);
                }
            }
            return mediaItemSize;
        }
Code explanation:
  • Sitecore.Data.ID.IsID() : This method takes in a string guid and returns true if it's a valid guid in Sitecore . The string must be 38 characters long, start with a curly brace "{" and end with a curly brace "}".
    For example :
    string itemId = "{AD1495DB-36FC-4B7A-80B6-D6170AB7F3B1}";
  • Sitecore.Data.ID.Parse() : This method takes in a string guid and returns a Sitecore ID object.
  • Sitecore.Context.Database.GetItem() : This method takes in a Sitecore ID object and return a Sitecore Item object.
  • MediaItem mediaItem = new MediaItem(sitecoreItem) : Using this piece of code, we are getting Sitecore Media Item object.
  • mediaItem.Size : Returns size of media item in bytes.
  • mediaItem.Extension : Returns file extension of media item. In my case; it was .pdf.
  • mediaItem.MimeType : Returns Mime Type of media item. In my case; it was application/pdf.
Comments and suggestions are most welcome. Happy coding!
