用标签导出word文档

welcomechenqi 2010-02-26 09:50:51

我用书签的方式导出word文档,在编译环境中正常,但是发布后就报错

报错的地方就是红色的那句

错误:
未将对象引用设置到对象的实例。
doc.Close(ref doNotSaveChanges, ref missingValue, ref missingValue);

代码:



Microsoft.Office.Interop.Word.ApplicationClass appWord = null;//应用程序 

            Microsoft.Office.Interop.Word.DocumentClass doc = null;//文档 

            try

            {

                appWord = new ApplicationClass();

                appWord.Visible = false;

                object objTrue = true;

                object objFalse = false;

                //object   objTemplate   =   "template.dot ";//模板绝对路径 

                object objTemplate = Server.MapPath("template.dot ");//模板相对路径 

                object objDocType = WdDocumentType.wdTypeDocument;

                doc = (DocumentClass)appWord.Documents.Add(ref   objTemplate, ref   objFalse, ref   objDocType, ref   objTrue);

                //生成word文档 

                object sq_depName = "depName"; //部门名



                // 给书签赋值 



                doc.Bookmarks.get_Item(ref sq_depName).Range.Text = wr.DepName;



                #region//生成word

                string fn = CreateFileName();

                object filename = Server.MapPath(".") + fn;

                //object filename = @"c:\test.doc";

                object miss = System.Reflection.Missing.Value;

                

                doc.SaveAs(ref   filename, ref   miss, ref   miss, ref   miss, ref   miss, ref   miss, ref   miss, ref   miss, ref   miss, ref   miss, ref   miss, ref   miss, ref   miss, ref   miss, ref   miss, ref   miss);

                #endregion



                //退出word,同时释放资源 

                object missingValue = Type.Missing;

                object doNotSaveChanges = WdSaveOptions.wdDoNotSaveChanges;

                /*错误地方*/doc.Close(ref   doNotSaveChanges, ref   missingValue, ref   missingValue);

             appWord.Application.Quit(ref   miss, ref   miss, ref   miss);

                doc = null;

                appWord = null;

            }

            catch (System.Exception ex)

            {

                //捕捉异常，如果出现异常则清空实例，退出word,同时释放资源 

                string aa = ex.ToString();

                object miss = System.Reflection.Missing.Value;

                object missingValue = Type.Missing;

                object doNotSaveChanges = WdSaveOptions.wdDoNotSaveChanges;

                doc.Close(ref   doNotSaveChanges, ref   missingValue, ref   missingValue);

                appWord.Application.Quit(ref   miss, ref   miss, ref   miss);

                doc = null;

                appWord = null;



            }
