bianwu 哈希表输出到 excel

一、输出到excel

函数：

    protected void InputFileTheme(object[] Header,object [] DataFileds,string sql,string filename)
        {
            SqlDBHandler dbHandler=this.getDBHandler();

            string strTemp;

            //hashTable.Add("laguage","513");//正文语种
            /*hashTable.Add("themetype3","504");//参考地图地域类别
            hashTable.Add("themetype4","505");//参考地图形式类别
            hashTable.Add("themetype5","508");//基础教材性质类别
            hashTable.Add("themetype6","506");//基础教材学科类别
            hashTable.Add("themetype8","519");//教辅性质

            hashTable.Add("useterm","510");//基础教材使用学期
            hashTable.Add("managemode","511");//编务管理类别
            hashTable.Add("electype","608");//电子出版物类型 (dictid=608)

            hashTable.Add("bindmode","516");//装帧形式

            Response.Write(sw);
            Response.End();
            dbHandler.Close();
        }

二、调用

this.InputFileTheme(header,dataFileds,strSql,"bookinfo");
