通过比较两个 Word 文档来获取差异

我们已经介绍了如何在 C# 和 VB.NET 中比较两个 Word 文档。从 Spire.Doc V8.12.14 开始，它支持在结构列表中获取两个 Word 文档之间的差异。本文将向您展示如何使用 Spire.Doc 通过比较两个 Word 文档来获取差异。

【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;

}

else if (para.IsDeleteRevision)
{
EditRevision delRevison = para.DeleteRevision;
EditRevisionType delType = delRevison.Type;

}

}
}
}
}

//Get the difference about revisions
DifferRevisions differRevisions = new DifferRevisions(doc1);
var insetRevisionsList = differRevisions.InsertRevisions;
var deletRevisionsList = differRevisions.DeleteRevisions;
}
}
}
