{

                MessageBox.Show(ex.Message);

            }

            finally

            {

                doc.Save();//save word

                CloseApp();//close word app

                CopyExcelData();//copy data again,*******************

            }

        }

关于关闭word对象

         public void CloseApp()
        {
            WordApp.Documents.Close(ref trueValue, ref missing, ref missing);
            WordApp.Quit(ref trueValue, ref missing, ref missing);
            System.Runtime.InteropServices.Marshal.ReleaseComObject(WordApp);
            GC.Collect();

            //this.KillExcelProcess();
        }

还有两个工具函数不再赘述，用来copy文件并且返回文件名private string CopyExcelData()；和private string CopyTemplateDoc()。
