一、输出到excel

函数：

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

                        {
                            strTemp=dr[DataFileds[len].ToString()].ToString().Trim();

            //Response.ContentEncoding=System.Text.Encoding.GetEncoding("unicode");
            Response.Write(sw);
            Response.End();
            dbHandler.Close();
        }

二、调用

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