SharePoint Document Library C# - Retrieve Document Version Details

In this article, I am going show how to read the document version details from SharePoint document.

Create data table for version History

        void CreateVersionHistoryTable()

        {

            try

            {

                dtVersionCollection = new DataTable();

                dtVersionCollection.Columns.Add("VersionId", typeof(string));

                dtVersionCollection.Columns.Add("VersionLabel", typeof(string));

                dtVersionCollection.Columns.Add("CreatedBy", typeof(string));

                dtVersionCollection.Columns.Add("Created", typeof(string));

                dtVersionCollection.Columns.Add("ModifiedBy", typeof(string));

                dtVersionCollection.Columns.Add("Modified", typeof(string));

            }

            catch (Exception)

            {

                throw;

            }

        }

Read document version details

void GetAllVersion()

        {

            try

            {

                CreateVersionHistoryTable();

               SPSite Site = new SPSite(URL);

                using (SPWeb web = Site.OpenWeb())

                {

                    SPList list = web.Lists[DocLibraryName];

                    SPListItem item = list.GetItemById(DocumentID);

                    SPListItemVersionCollection  Fileversioncollection = item.Versions;

                    foreach (SPListItemVersion version in Fileversioncollection)

                    {

                        DataRow dr = dtVersionCollection.NewRow();

                        dr["VersionId"] = version.VersionId;

                        dr["Created"] = version.Created;

                        dr["Modified"] = version["Modified"];

                        dr["VersionLabel"] = version.VersionLabel;

                        try

                        {

                            SPFieldUserValue userValue = new SPFieldUserValue(web, version.CreatedBy.ToString());

                            SPUser userObject = userValue.User;

                            dr["CreatedBy"] = userObject;

                        }

                        catch (Exception)

                        {    }

                        try

                        {

                            SPFieldUserValue userValue = new SPFieldUserValue(web, version["Modified By"].ToString());

                            SPUser userObject = userValue.User;

                                dr["ModifiedBy"] = userObject;

                        }

                        catch (Exception)

                        { }

                        dtVersionCollection.Rows.Add(dr);

                    }

                }

            }

            catch (Exception)

            {

                 return;

            }

        }
