遇到的问题：

1.由于需要每一个页面显示一个单子、所以每次根据ProcInstIDArr[] 循环创建完以后、调用InsertBreak()生成下一个空白页面、导致最后会出现一个空白页面、

　　　　　　当时想到的是怎么删除最后一个空白页、通过在网上查询，说通过以下代码可以删除、最后拿下来试验发现无法实现。

 //Word.Range range1, range2;

                //// 跳转种类

                //object objWhat = Word.WdGoToItem.wdGoToPage;

                //// 跳转位置

                //object objWhich = Word.WdGoToDirection.wdGoToLast;

                //// 转向最后一页

                //WordApp.Selection.GoTo(ref objWhat, ref objWhich, ref Nothing, ref Nothing);

                //// Range取得

                //range1 = WordApp.Selection.Range;

                //range2 = WordApp.ActiveDocument.Range(ref Nothing, ref Nothing);

                //object start = range1.Start;

                //object end = range2.End;

                //// 删除最后一页

                //WordApp.ActiveDocument.Range(ref start, ref end).Delete(ref Nothing, ref Nothing);

　　　　　　中午跟同事请教：理理思路。发现完全是我想复杂了、只想着怎么删除，没有想过不去生成。最后通过一个if判断轻松解决问题。

　　　　　　遇到问题不要想的太复杂。

　　　　 2.还有一个关于winword.exe进程未杀死的问题、这个是今天早上发现的，早上打开服务器，发现服务器上出现N个word文档。进程里还有不下30个winword.exe进　　　　　　程、详情点击
