for循环输出111111111

Question

    public string  tuxing()
    {            
        DataTable dt = new Eastea.BusLogic.GraphicalGet().Getgraphical();
        StringBuilder JsonString = new StringBuilder();
        for (var i = 0; i < dt.Rows.Count; i++)
        {
            name = dt.Rows[i]["name"].ToString();
            gz = Convert.ToInt32(dt.Rows[i]["chengji"].ToString());
            //Response.Write(name);
            //Response.Write(gz);
        }
        //Response.End();
        //Response.End();
        return " " + name + "  " + gz + " ";
    }

以上是后台代码，我return之后在前台显示，只显示获取到数据库的最后一条数据，如果在循环里直接Response.Write(name);输出就可以全部输出来，我想return到前台然后全部输出该怎么写啊。。。在线等啊

你的变量name,gz只保存住了最后一次赋的值

name += dt.Rows[i]["name"].ToString();
gz += Convert.ToInt32(dt.Rows[i]["chengji"].ToString());
