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）

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）
