如何在VS2017中合并Word文件 [英] How to Merge Word files in VS2017

问题描述

我已将多个rdlc 报告呈现并导出为word文档（.doc）。现在我希望能够将这些文件合并到vs2017中的一个word文档中，作为同一过程的一部分。我以前用pdf文件做了同样的事情，代码
如下。我如何修改它以适用于word文件。或者它是一个完全不同的过程？

I have rendered and exported multiple rdlc reports as word documents (.doc). Now I want to be able to merge these files into one word document in vs2017 as part of the same process. I have previously done the same thing with pdf files with the code below. How would I need to modify it to work for a word file. Or is it a completely different process?

谢谢。

推荐答案

假设您可以将Word文档呈现为Open XML（.docx ）文件而不是旧的.doc格式，你可以使用DocumentBuilder，它是
打开XML电动工具合并生成的Open XML文档。 对于SQL Server Reporting Services（.rdl），要使用的格式为"WORDOPENXML"。但我不确定.rdlc文件是否支持
，因为我没有使用它们。

Assuming you can render the Word documents as Open XML (.docx) files rather than the older .doc format, you can use the DocumentBuilder which is part of the Open XML Power Tools to merge the resulting Open XML documents.  For SQL Server Reporting Services (.rdl), the format to use is "WORDOPENXML" but I'm not sure if that's supported for .rdlc files since I haven't used them much.
