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）

        /// <summary>
        /// 发送Email
        /// </summary>
        /// <param name="BILL_NO">记录编号</param>
        /// <param name="JOB_MAIL">收件人CODE</param>
        public JsonResult SendEmail(string BILL_NO, string JOB_MAIL)
        {
            JsonResult JsonResult = new JsonResult();
            JsonResultInfo result = new JsonResultInfo();
            try
            {
                #region 附件Word模板寫入數據
                WF_MEETINGEntity model = wmee.GetModel(BILL_NO);
                byte[] byteArray = (byte[])model.REMARK;
                var strREMARK = System.Text.Encoding.UTF8.GetString(byteArray);
                //最终要发送的文件地址
                string path = "";
                var wordPath = "";
                if (strREMARK.IndexOf("{\\rtf") < 0)
                {
                    #region REMARK为RTF格式处理方法（html富文本框内容处理）
                    //将数据整理到视图模板
                    var viewModel = AssignmentModel(model);
                    //创建完整的html源码
                    var htmlCode = CreateHtml(viewModel);
                    
                    //创建html文件路径
                    var htmlBasePath = "/File/SendEmail/REMARK";

                    //这一块原本的思路是生成html文件，下一步再转为word文档（但是html文件转为word文档的思路很难实现，所以放弃了）
                    //var htmlPath = Path.Combine(htmlBasePath, "REMARK.html");
                    //string filePath = Server.MapPath(htmlPath);
                    //using (StreamWriter sw = new StreamWriter(filePath))
                    //{
                    //    sw.Write(htmlCode);
                    //}

                    //如果创建一个新文档并保存是这样写的：
                    wordPath = Path.Combine(htmlBasePath, "會議記錄.doc");
                    System.IO.File.WriteAllText(Server.MapPath(wordPath), htmlCode);

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）
