C# .NET Html代码生成Word并发送Email

1.功能：

我要做的一个功能就是点击【发送邮件】按钮，生成一个word文档并发送邮件（但是图片需要获取到图片并转成Base64才可以加载到图片，等我写完后会在后面续加上方法）

2.功能概括：

本文发送Email的方法使用了两种生成Word的方式：

（1）System.IO.File.WriteAllText(Server.MapPath(wordPath), htmlCode);

wordPath：自己指定的word将要生成的文件路径

htmlCode：拼好的html源码

（2）写好的word模板，使用域方式插入数据

3.代码块（一共三个方法）

SendEmail（发送Email方法）

  1         /// <summary>
  2         /// 发送Email
  3         /// </summary>
  4         /// <param name="BILL_NO">记录编号</param>
  5         /// <param name="JOB_MAIL">收件人CODE</param>
  6         public JsonResult SendEmail(string BILL_NO, string JOB_MAIL)
  7         {
  8             JsonResult JsonResult = new JsonResult();

 14                 byte[] byteArray = (byte[])model.REMARK;
 15                 var strREMARK = System.Text.Encoding.UTF8.GetString(byteArray);

CreateHtml（创建完整的html源码）

这个就不详细贴源码了，毕竟每个人页面不一样意义不大，就是在html页面画好，在后台贴源码就是了。返回的是拼好的HTML源码

注意！头部<html>标签需用这个（这个是网上百度的，参考的这个链接：https://www.cnblogs.com/wendj/p/6699885.html）

欢迎小伙伴们评论下方技术指导<（^_^）>
