通过Word实现表单套打

1.在Word中做好表单模板，在对应的地方设置好对应的关键字(Key)；

2.添加扩展Microsoft.Office.Interop.Word.dll（添加引用->程序集->扩展）；

3.替换代码：

public partial class _Default : Page
    {
        private  Dictionary<string, string> dic = new Dictionary<string, string>();
        protected void Page_Load(object sender, EventArgs e)
        {
            dic.Add("[文别]", "测试数据源");
            dic.Add("[密级]", "测试数据源");
            dic.Add("[缓急]", "测试数据源");
            dic.Add("[时限]", "测试数据源");
            dic.Add("[文件标题]", "测试数据源");
            dic.Add("[附件]", "测试数据源");
            dic.Add("[主送]", "测试数据源");
            dic.Add("[抄送]", "测试数据源");
            dic.Add("[签发]", "测试数据源");
            dic.Add("[分管领导意见]", "测试数据源");
            dic.Add("[办公室审核]", "测试数据源");
            dic.Add("[会办处室意见]", "测试数据源");
            dic.Add("[主板处室负责人意见]", "测试数据源");
            dic.Add("[主板处室拟稿人]", "测试数据源");
            dic.Add("[联系电话]", "测试数据源");
            WordReplace(@"E:上海市农业委员会办文单-新版.doc", "[文别]", "[新文别]");
        }
