需求背景

        因为疫情爆发，进入一级响应状态，公安部门进行了严格出入境管理，需要对每个出入境的人进行状态跟踪。

        疫情专班会将出入境的每个人员汇总在一张Excel表中，如下图所示：

 

 

         每一行对应一个人员信息，一个人员信息需要生成一个协查函，需要将人员信息填入到固定格式的协查函中，协查函的格式如下图所示：

功能实现 

        功能实现分成两个部分，一是从Excel读取数据，二是将读取的数据批量输出到Word文档。

从Excel读取数据使用NPOI，输出到word文档使用Microsoft Word Object Library.

NPOI可以在NuGet程序包中搜索到：

 Microsoft Word Object Library.可以在类库中引用到。

 考虑到速度，功能用winform程序实现。

 实现效果

启动程序时：

选择Excel：

导入Excel：

 导出到Word：

打开Word看看：

 

 在开发之前需要对创建一个Word(dot格式)模板文件，内容格式很协查函一样，然后再需要插入数据的地方设置书签即可。

 程序代码

ExcelHelp类用于将选中的Excel数据导入到datatable中。
