Repeater绑定数据 后台自定义的DataTable

前台：
<asp:Repeater ID="Repeater1" runat="server">
            <ItemTemplate>
                回复序号：<%#DataBinder.Eval(Container.DataItem, "Number").ToString()%>楼<br />
                头像：<asp:Image ID="Image2" ImageUrl='<%#DataBinder.Eval(Container.DataItem, "RestImg").ToString()%>' runat="server" />
                回复人：<%#DataBinder.Eval(Container.DataItem, "RestUser").ToString()%><br />
                回复内容：<%#DataBinder.Eval(Container.DataItem, "RestContent").ToString()%><br />
                回复时间：<%#DataBinder.Eval(Container.DataItem, "RestTime").ToString()%><br />
            </ItemTemplate>
        </asp:Repeater>

后台：
public void BindRest()
    {
        string Id = "8";
        RestoresManager reMana = new RestoresManager();
        DataTable dtRest = reMana.SelectRestListBySubjId(Id);
        DataTable dt = new DataTable();
        dt.Columns.Add("Number", typeof(string));
        dt.Columns.Add("RestImg", typeof(string));
        dt.Columns.Add("RestUser", typeof(string));
        dt.Columns.Add("RestContent", typeof(string));
        dt.Columns.Add("RestTime", typeof(string));
        for (int i = 0; i < dtRest.Rows.Count; i++)
        {
            DataRow dr = dt.NewRow();
            dr["Number"] = Convert.ToString(i + 1);
            dr["RestImg"] = dtRest.Rows[i]["Img"].ToString();
            dr["RestUser"] = dtRest.Rows[i]["UserName"].ToString();
            dr["RestContent"] = dtRest.Rows[i]["ResContent"].ToString();
            dr["RestTime"] = dtRest.Rows[i]["Time"].ToString();
            dt.Rows.Add(dr);
        }
        Repeater1.DataSource = dt;
        Repeater1.DataBind();
    }
