以编程方式比较Word文档 [英] programmatically comparing word documents

问题描述

我需要比较两个Office文档，在这种情况下是两个Word文档，并提供一个差异，这与SVN中显示的内容有些相似.不能达到这个程度，但至少能够突出差异.

I need to compare two office documents, in this case two word documents and provide a difference, which is somewhat similar to what is show in SVN. Not to that extent, but at least be able to highlight the differences.

我尝试使用Office COM dll到此为止.

I tried using the office COM dll and got this far..

object fileToOpen = (object)@"D:\doc1.docx";
string fileToCompare = @"D:\doc2.docx";

WRD.Application WA = new WRD.Application();

Document wordDoc = null;

wordDoc = WA.Documents.Open(ref fileToOpen, Type.Missing, Type.Missing, Type.Missing, Type.Missing,      Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
wordDoc.Compare(fileToCompare, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

有关进一步进行操作的任何提示?这将是一个点击率很高的Web应用程序.使用office com对象是正确的方法吗，或者我还有其他可以看的东西吗?

Any tips on how to proceed further? This will be a web application having a lot of hits. Is using the office com object the right way to go, or are there any other things I can look at?

推荐答案

我同意约瑟夫(Joseph)关于区分字符串的意见.我还建议您使用专用的差异化引擎(在此处找到几个):任何.NET的体面文本差异/合并引擎?)，可以帮助您避免进行差异化时遇到的一些常规陷阱.

I agree w/ Joseph about diff'ing the string. I would also recommend a purpose-built diffing engine (several found here: Any decent text diff/merge engine for .NET?) which can help you avoid some of the normal pitfalls in diffing.
