C# 调用word并读取里面的内容解决思路

 protected void Button1_Click(object sender, EventArgs e)        {            object oReadOnly = true;            object oMissing = System.Reflection.Missing.Value;            object oFileName ="E:/文档.docx";            Word._Application oWord;            Word._Document oDoc;            oWord = new Word.Application();            //oWord.Visible = true;            oDoc = oWord.Documents.Open(ref oFileName, ref oMissing, ref oReadOnly, ref oMissing, ref oMissing,                ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing);            returnContent = oDoc.Content.Text;            oDoc.Close(ref oMissing, ref oMissing, ref oMissing);            WorkLog wl = new WorkLog();            wl.Acnt_id = "111";            wl.Del_flg = false;            wl.Dma_code = "";            wl.Log_body = returnContent;            wl.Log_time = DateTime.Now;            wl.Mdf_time = DateTime.Now;            AccountService As = new AccountService();            Account acc = As.Login("test", "test");            As.AddWorkLog(wl);            //关闭COM            oWord.Quit(ref oMissing, ref oMissing, ref oMissing);            //File.Delete(oFileName.ToString());        }    }
