Document version size in Sharepoint

The below code will calculate the document version size for each item for a single document library.

using (SPSite site = new SPSite("http://Site_URL/")) //Specify your SiteURL

            {

                using (SPWeb web = site.OpenWeb())

                {

                    SPList objList = web.Lists["Doclib"];//Document library Name

                    SPQuery objQuery = new SPQuery();

                   

                    objQuery.ViewAttributes = "Scope=\"Recursive\"";

                    SPListItemCollection objItemColl = objList.GetItems(objQuery);

                    foreach (SPListItem objItem in objItemColl)

                    {

                        long versionSize = 0;

                        SPListItemVersionCollection objVerisionColl = objItem.Versions;

                        foreach (SPListItemVersion objVersion in objVerisionColl)

                        {

                            int versionID = objVersion.VersionId;

                            string strVersionLabel = objVersion.VersionLabel;

                            SPListItem objLstItm = objVersion.ListItem;

                            versionSize = versionSize + objLstItm.File.Length;

                           

                        }

                        Console.WriteLine("Item:" + objItem.Name + " Version Count:" + objVerisionColl.Count + " Size:" + versionSize.ToString());

                       

                    }

                }

            }
