Word控件Spire.Doc 【文档操作】教程(十一)：如何在C#中按分页符拆分word文档

借助 Spire.Doc for .NET，我们不仅可以按节拆分 word 文档，还可以按分页符拆分。我们已经介绍

请查看以下原始word文档的屏幕截图，该文档在第一页和第二页的末尾有两个分页符。

现在参考以下详细步骤将其按分页符拆分为 3 个单独的文档。

第 1步：创建一个word文档并加载原始word文档。

Document original = new Document();original.LoadFromFile("New Zealand.docx");

第 2 步：创建一个新的 Word 文档并在其中添加一个部分。

Document newWord = new Document();Section section = newWord.AddSection();

第 3 步：将原word文档按照分页符拆分成单独的文档。

int index = 0;//traverse through all sections of original documentforeach (Section sec in original.Sections){//traverse through all body child objects of each sectionforeach (DocumentObject obj in sec.Body.ChildObjects){if (obj is Paragraph){Paragraph para = obj as Paragraph;//add paragraph object in original section into section of new documentsection.Body.ChildObjects.Add(para.Clone());foreach (DocumentObject parobj in para.ChildObjects){if (parobj is Break && (parobj as Break).BreakType == BreakType.PageBreak){//get the index of page break in paragraphint i = para.ChildObjects.IndexOf(parobj);//remove the page break from its paragraphsection.Body.LastParagraph.ChildObjects.RemoveAt(i);//save the new document to a .docx file.newWord.SaveToFile(String.Format("result/out-{0}.docx", index), FileFormat.Docx);index++;//create a new documentnewWord = new Document();//add a section for documentsection = newWord.AddSection();//add paragraph object in original section into section of new documentsection.Body.ChildObjects.Add(para.Clone());if (section.Paragraphs[0].ChildObjects.Count == 0){//remove the first blank paragraphsection.Body.ChildObjects.RemoveAt(0);}else{//remove the child objects before the page breakwhile (i >= 0){section.Paragraphs[0].ChildObjects.RemoveAt(i);i--;}}}}}if (obj is Table){//add table object in original section into section of new documentsection.Body.ChildObjects.Add(obj.Clone());}}}//save to a .docx filenewWord.SaveToFile(String.Format("result/out-{0}.docx", index), FileFormat.Docx);

输出：
