c#读取word文本？

Question

VS里用c#读取word文本并显示出来，请问如何操作？
doc = app.Documents.Open(ref fileName,
ref unknow, ref unknow, ref unknow, ref unknow, ref unknow,
ref unknow, ref unknow, ref unknow, ref unknow, ref unknow,
ref unknow, ref unknow, ref unknow, ref unknow, ref unknow);
以上的这段代码怎样理解？
谢谢！

Answer 1

[code="C#"]
Word.ApplicationClass wordApp=new ApplicationClass();
object file=path;（//译注:这个path是函数的参数，表示Word的路径）
object nullobj=System.Reflection.Missing.Value;

Word.Document doc = wordApp.Documents.Open(
ref file, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj);
doc.ActiveWindow.Selection.WholeStory();
doc.ActiveWindow.Selection.Copy();
IDataObject data=Clipboard.GetDataObject();
txtFileContent.Text=data.GetData(DataFormats.Text).ToString();
doc.Close();
