利用 Microsoft.Office.Interop.Word 组件进行比较。引入命名空间：using Word2013 = Microsoft.Office.Interop.Word;

代码如下：

/// <summary>
/// 进行与Word2013.Document类创建时指定的文件比较，
/// 然后将差异显示在targetFile，并保存退出
/// </summary>
/// <param name="sourceFile">源文件（修改前文件）</param>
/// <param name="targetFile">目标文件（修改后文件）</param>
public static void CompareWordFile(string sourceFile, string targetFile)
{
object missing = System.Reflection.Missing.Value;
object sFileName = sourceFile;
var tFileName = targetFile;
var wordApp = new Word2013.Application();
wordApp.Caption = "CompareWordApp";
wordApp.Visible = false; var wordDoc = wordApp.Documents.Open(ref sFileName, ref missing, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing); wordDoc.TrackRevisions = true;
wordDoc.ShowRevisions = true;
wordDoc.PrintRevisions = true; object comparetarget = Word2013.WdCompareTarget.wdCompareTargetSelected;
object addToRecentFiles = false;
wordDoc.Compare(tFileName, ref missing, ref comparetarget, ref missing, ref missing, ref addToRecentFiles,
ref missing, ref missing); int changeCount = wordApp.ActiveDocument.Revisions.Count;
Object saveChanges = Word2013.WdSaveOptions.wdSaveChanges;
wordDoc.Close(ref saveChanges, ref missing, ref missing);
wordApp.Quit(ref saveChanges, ref missing, ref missing); KillWordProcess("CompareWordApp");
}
