c# - 以编程方式比较word文档

Question

我需要比较两个office文档，在本例中是两个word文档并提供差异，这有点类似于SVN中显示的内容。不至于到那种程度，但至少能够突出差异。

我尝试使用 office COM dll 并得到了这一步..

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);

关于如何进一步进行的任何提示？这将是一个具有大量点击率的 Web 应用程序。使用 office com 对象是正确的方法吗，或者还有其他我可以看的东西吗？

Answer 1

您应该使用 Document 类来比较文件并在 Word 文档中打开结果。

using OfficeWord = Microsoft.Office.Interop.Word;

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

var app = Global.OfficeFile.WordApp;

object readOnly = false;
object AddToRecent = false;
object Visible = false;

OfficeWord.Document docZero = app.Documents.Open(fileToOpen, ref missing, ref readOnly, ref AddToRecent, Visible: ref Visible);

docZero.Final = false;
docZero.TrackRevisions = true;
docZero.ShowRevisions = true;
docZero.PrintRevisions = true;

//the OfficeWord.WdCompareTargetNew defines a new file, you can change this valid value to change how word will open the document
docZero.Compare(fileToCompare, missing, OfficeWord.WdCompareTarget.wdCompareTargetNew, true, false, false, false, false);
