       }

    }
}

这样引用：

public void Test(HttpContext context)
       {
           try
           {
               string path = context.Server.MapPath("RiskNoticeDoc");
               string templatePath = path + @"\RiskNoticeModel.dot";
               var wop = new WordOp();
               wop.OpenTempelte(templatePath);
               wop.FillLable("zs", "测试");
               wop.SaveAs(@"E:\Projects\微信公共服务平台项目\WeixinService\WeixinService.Web\RiskNoticeDoc\zw.docx", true);
               wop.Quit();
               //context.Response.Redirect(@"/download/savetest.doc");//做个跳转用于下载. 
           }
           catch (Exception)
           {
               throw;
           }
       }

报错：
