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;           }       }
