使用OpenXml和C#复制Word文档 [英] Duplicating Word document using OpenXml and C#

问题描述

我正在使用Word和OpenXml在C#ASP.NET Web应用程序中提供邮件合并功能:

I am using Word and OpenXml to provide mail merge functionality in a C# ASP.NET web application:

1)上载了带有多个预定义字符串以进行替换的文档.

1) A document is uploaded with a number of pre-defined strings for substitution.

2)使用OpenXML SDK 2.0打开Word文档，获取mainDocumentPart作为字符串，然后使用Regex执行替换.

2) Using the OpenXML SDK 2.0 I open the Word document, get the mainDocumentPart as a string and perform the substitution using Regex.

3)然后，我使用OpenXML创建一个新文档，添加一个新的mainDocumentPart并将替换产生的字符串插入到该mainDocumentPart中.

3) I then create a new document using OpenXML, add a new mainDocumentPart and insert the string resulting from the substitution into this mainDocumentPart.

但是，所有格式/样式等都将在新文档中丢失.

However, all formatting/styles etc. are lost in the new document.

我想我可以分别复制和添加样式，定义，注释部分等，以模仿原始文档.

I'm guessing I can copy and add the Style, Definitions, Comment parts etc.. individually to mimic the orginal document.

但是，有没有一种方法可以使用Open XML复制文档，从而可以对新副本执行替换?

However is there a method using Open XML to duplicate a document allowing me to perform the substitutions on the new copy?

谢谢.

推荐答案

这段代码应该将现有文档的所有部分复制到新文档中.

This piece of code should copy all parts from an existing document to a new one.

using (var mainDoc = WordprocessingDocument.Open(@"c:\sourcedoc.docx", false))
using (var resultDoc = WordprocessingDocument.Create(@"c:\newdoc.docx",
  WordprocessingDocumentType.Document))
{
  // copy parts from source document to new document
  foreach (var part in mainDoc.Parts)
    resultDoc.AddPart(part.OpenXmlPart, part.RelationshipId);
  // perform replacements in resultDoc.MainDocumentPart
  // ...
}
