在asp.net中阅读Doc和Docx文件

Question

阅读Doc和Docx文件？ 我可以使用什么dll来阅读doc和docx文件？

string path= @"D:\Resume02\test.doc";

private bool SearchWordIsMatched(string path, string searchKeyWord)
{
    try
    {       

        Microsoft.Office.Interop.Word.ApplicationClass wordApp = new ApplicationClass();
        object file = path;
        object nullobj = System.Reflection.Missing.Value;
        object readOnly = true;
        Microsoft.Office.Interop.Word.Document doc = wordApp.Documents.Open(
            ref file, ref nullobj, ref readOnly,
                                              ref nullobj, 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();
        string d = data.GetData(DataFormats.Text).ToString();
        d.ToLower();
        if (d.ToLower().Contains(searchKeyWord.ToLower()))
        {
            object doNotSaveChanges = Microsoft.Office.Interop.Word.WdSaveOptions.wdDoNotSaveChanges;
            object originalFormat = Microsoft.Office.Interop.Word.WdOriginalFormat.wdWordDocument;
            object routeDocument = true;
            ((_Document)doc).Close(ref doNotSaveChanges, ref originalFormat, ref routeDocument);
            return true;
        }
        else
        {
            return false;
        }           
    }
    catch (System.Exception ex)
    {
        throw ex;
    }
}
