如何通过代码添加复选框

Question

我正在尝试实现一种图片选择形式，我希望在代码添加的每张图片旁边都有一个复选框，我希望循环中的每个复选框都有不同的ID。我试图在第二个for循环中插入复选框（迭代数据表中的每个图片）。

这是我的代码：

string d = (string)Session["gouser"];
DataTable l = DAL.SelectFromTable(" Select * FROM [ClothesCatig] WHERE [UserID]='" + d + "'");

for (int i = 0; i < l.Rows.Count; i++)
{
    DataTable m = DAL.SelectFromTable(" Select * FROM [Closet] WHERE [UserID]='" + d + "' and [catig]='" + l.Rows[i][2].ToString() + "'");
    if (m.Rows.Count > 0)
    {
        Response.Write("<center><div class='container12'>");
        Response.Write("<h4 class='ch'style='background-color: #985216;'>" + l.Rows[i][2] + "</h4>");
        Response.Write("<table class='table1'><tr>");
        for (int j = 0; j < m.Rows.Count; j++)
        {      
            Response.Write("<td><center><img src='images/hanger.png'/ width='80px'/>&nbsp;</br><img src='Cloth/"
                    + m.Rows[j][5].ToString() + "' width='80px'/></center></td>");
        }
        Response.Write("</table></tr>");
        Response.Write("</div></center>");
    }
}
