昨天做了下導入導出Excel文件，今天研究了下導出Word文件。 從網上找了半天才找到了一個能導出到指定模板的，在這裏總結下。

導出模板原理就是利用的替換占位符。

我這裏先建立好了一個模板，

接下來寫代碼進行導出，

前端就一段AJAX調用，這裏我就不寫了，直接上後端代碼,看下面：

     /// <summary>
        /// 導出Word文件
        /// </summary>
        /// <returns></returns>

            dc = tblDatas.Columns.Add("ID", Type.GetType("System.Int32"));
            dc.AutoIncrement = true;//自動增加
            dc.AutoIncrementSeed = 1
 
;//起始為1
            dc.AutoIncrementStep = 1;//步長為1
