How C # Merges and splits Word documents

Overview

For easy document management, storage, and transport, we often want to split some documents into multiple subdocuments, or merge multiple documents into one document. In this article, you'll describe the methods for splitting and merging Word documents. The following example will contain these points:

1. Merging Word documents
   1.1 Create a new page to merge into a document
   1.2 Merge to document immediately above
2. Splitting a Word document
   2.1 Splitting by section break
   2.2 Split by Page break

The tools used

• Free Spire.doc for. NET 6.3
• Visual Studio

Example operations

First, Merge Word documents
(i) Merging new pages into documents
"C #"

using Spire.Doc;namespace MergeWord_Doc{    class Program    {        static void Main(string[] args)        {            //创建两个文档，加载需要合并的文件            Document doc1 = new Document(@"C:\Users\Administrator\Desktop\TradeNegotiation.docx");            Document doc2 = new Document(@"C:\Users\Administrator\Desktop\DisputeSettlement.docx");            //调用InsertTextFromFile()方法，将文档2合并到文档1            string fileName = @"C:\Users\Administrator\Desktop\DisputeSettlement.docx";            doc1.InsertTextFromFile(fileName, FileFormat.Docx2013);            //保存文件            doc1.SaveToFile("MergedDocument.docx", FileFormat.Docx2013);        }    }}

Debug run the project, generate the file as shown in:

(ii) Immediately following the merger into the document
"C #"

using Spire.Doc;using Spire.Doc.Documents;namespace MergeWord2_Doc{    class Program    {        static void Main(string[] args)        {            //创建两个文档，并加载需要合并的两个文件            Document doc1 = new Document(@"C:\Users\Administrator\Desktop\TradeNegotiation.docx");            Document doc2 = new Document(@"C:\Users\Administrator\Desktop\DisputeSettlement.docx");            //获取文档1的最后一个Section            Section lastSection = doc1.LastSection;            //遍历文档2中的所有section，复制所有section到文档1            foreach (Section section in doc2.Sections)            {                foreach (Paragraph paragraph in section.Paragraphs)                {                    lastSection.Paragraphs.Add(paragraph.Clone() as Paragraph);                }            }            //将合并的文档另存为一个新文档            doc1.SaveToFile("Merged.docx", FileFormat.Docx2013);        }    }}

Second, split Word document
(i) Split by section break
"C #"

using Spire.Doc;using System;namespace SplitWord_Doc{    class Program    {        static void Main(string[] args)        {            //创建一个Document类对象，并加载需要拆分的文档            Document document = new Document();            document.LoadFromFile(@"C:\Users\Administrator\Desktop\sample.docx");            //实例化Document对象             Document newWord;            //遍历文档所有section，复制文档每个section并分别保存到新建的文档，同时将拆分的文档保存到指定路径            for (int i = 0; i < document.Sections.Count; i++)            {                newWord = new Document();                newWord.Sections.Add(document.Sections[i].Clone());                newWord.SaveToFile(String.Format(@"results\out_{0}.docx", i));            }        }    }}

(ii) Split by page break
"C #"
