C# 如何合并、拆分Word文档
1、（一）以新建一页合并到文档
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);
}
}
}
2、（二）紧接上文合并到文档
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);
}
}
}
1、（一）按分节符拆分
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));
}
}
}
}
2、（二）按分页符拆分
C#
using System;
using Spire.Doc;
using Spire.Doc.Documents;
namespace Split_Word_Document_by_Page_Break
{
class Program
{
static void Main(string[] args)
{
//实例化一个Document类，加载文档
Document original = new Document();
original.LoadFromFile(@"C:\Users\Administrator\Desktop\test.docx");
//实例化Document类对象，并添加section
Document newWord = new Document();
Section section = newWord.AddSection();
//根据分页来拆分文档
int index = 0;
//遍历文档所有section
foreach (Section sec in original.Sections)
{
//遍历文档所有子对象
foreach (DocumentObject obj in sec.Body.ChildObjects)
{
if (obj is Paragraph)
{
Paragraph para = obj as Paragraph;
//复制并添加原有段落对象到新文档
section.Body.ChildObjects.Add(para.Clone());
//遍历所有段落子对象
foreach (DocumentObject parobj in para.ChildObjects)
{
if (parobj is Break && (parobj as Break).BreakType == BreakType.PageBreak)
{
//获取段落分页并移除，保存新文档到文件夹
int i = para.ChildObjects.IndexOf(parobj);
section.Body.LastParagraph.ChildObjects.RemoveAt(i);
newWord.SaveToFile(String.Format("results/out-{0}.docx", index), FileFormat.Docx);
index++;
//实例化Document类对象，添加section，将原文档段落的子对象复制到新文档
newWord = new Document();
section = newWord.AddSection();
section.Body.ChildObjects.Add(para.Clone());
if (section.Paragraphs[0].ChildObjects.Count == 0)
{
//移除第一个空白段落
section.Body.ChildObjects.RemoveAt(0);
}
else
{
//删除分页符前的子对象
while (i >= 0)
{
section.Paragraphs[0].ChildObjects.RemoveAt(i);
i--;
}
}
}
}
}
//若对象为表格，则添加表格对象到新文档
if (obj is Table)
{
section.Body.ChildObjects.Add(obj.Clone());
}
}
}
//拆分后的新文档保存至指定文档
newWord.SaveToFile(String.Format("results/out-{0}.docx", index), FileFormat.Docx);
}
}
}
