C#将内容导出Word到指定模板

昨天做了下导入导出Excel文件，今天研究了下导出Word文件。 从网上找了半天才找到了一个能导出到指定模板的，在这里总结下。

导出模板原理就是利用的替换占位符。

我这里先建立好了一个模板，

接下来写代码进行导出，

前端就一段AJAX调用，这里我就不写了，直接上后端代码,看下面：

     /// <summary>
        /// 导出Word文件
        /// </summary>
        /// <returns></returns>
        [HttpPost]
        public ActionResult LeadWord()
        {
            #region 动态创建DataTable数据
            DataTable tblDatas = new DataTable("Datas");
            DataColumn dc = null;
            //赋值给dc，是便于对每一个datacolumn的操作
            dc = tblDatas.Columns.Add("ID", Type.GetType("System.Int32"));
            dc.AutoIncrement = true;//自动增加
            dc.AutoIncrementSeed = 1;//起始为1
            dc.AutoIncrementStep = 1;//步长为1
            dc.AllowDBNull = false;//
            dc = tblDatas.Columns.Add("name", Type.GetType("System.String"));
            dc = tblDatas.Columns.Add("sex", Type.GetType("System.String"));
            dc = tblDatas.Columns.Add("age", Type.GetType("System.String"));
            dc = tblDatas.Columns.Add("str1", Type.GetType("System.String"));
            dc = tblDatas.Columns.Add("str2", Type.GetType("System.String"));
            dc = tblDatas.Columns.Add("str3", Type.GetType("System.String"));
            dc = tblDatas.Columns.Add("str4", Type.GetType("System.String"));
            dc = tblDatas.Columns.Add("str5", Type.GetType("System.String"));
            dc = tblDatas.Columns.Add("str6", Type.GetType("System.String"));
            dc = tblDatas.Columns.Add("remark", Type.GetType("System.String"));
            DataRow newRow;
            newRow = tblDatas.NewRow();
            newRow["name"] = "张三";
