We have introduced how to compare two Word documents in C# and VB.NET. From Spire.Doc V8.12.14, it supports to get the differences between two Word documents in a structure list. This article will show you how to use Spire.Doc to get the differences by comparing two Word documents.
C#
using Spire.Doc; using Spire.Doc.Documents; using Spire.Doc.Fields; using Spire.Doc.Formatting.Revisions; using System; namespace GetWordDifferences { class Program { static void Main(string[] args) { //Load the first Word document Document doc1 = new Document(); doc1.LoadFromFile("Sample1.docx"); //Load the second Word document Document doc2 = new Document(); doc2.LoadFromFile("Sample2.docx"); //Compare the two Word documents doc1.Compare(doc2, "Author"); foreach (Section sec in doc1.Sections) { foreach (DocumentObject docItem in sec.Body.ChildObjects) { if (docItem is Paragraph) { Paragraph para = docItem as Paragraph; if (para.IsInsertRevision) { EditRevision insRevison = para.InsertRevision; EditRevisionType insType = insRevison.Type; string insAuthor = insRevison.Author; DateTime insDateTime = insRevison.DateTime; } else if (para.IsDeleteRevision) { EditRevision delRevison = para.DeleteRevision; EditRevisionType delType = delRevison.Type; string delAuthor = delRevison.Author; DateTime delDateTime = delRevison.DateTime; } foreach (ParagraphBase paraItem in para.ChildObjects) { if (paraItem.IsInsertRevision) { EditRevision insRevison = paraItem.InsertRevision; EditRevisionType insType = insRevison.Type; string insAuthor = insRevison.Author; DateTime insDateTime = insRevison.DateTime; } else if (paraItem.IsDeleteRevision) { EditRevision delRevison = paraItem.DeleteRevision; EditRevisionType delType = delRevison.Type; string delAuthor = delRevison.Author; DateTime delDateTime = delRevison.DateTime; } } } } } //Get the difference about revisions DifferRevisions differRevisions = new DifferRevisions(doc1); var insetRevisionsList = differRevisions.InsertRevisions; var deletRevisionsList = differRevisions.DeleteRevisions; } } }
