.net 下word导入textbox

只需要引入Microsoft.Office.Interop.Word

Microsoft.Office.Interop.Word.Application app = new Application();
                object missing = Type.Missing;
                object obj = FileUpload1.PostedFile.FileName.ToString();
                Microsoft.Office.Interop.Word.Document WDoc = app.Documents.Open(ref obj, 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);
                txtText.Text = WDoc.Content.Text;

                if (WDoc != null)
                {
                    WDoc.Close(ref missing, ref missing, ref missing);
                    WDoc = null;
                }
                if (app != null)
                {
                    app.Quit(ref missing, ref missing, ref missing);
                    app = null;
                }
