ASP.NET -如何在中继器中编写中继器

<asp:Repeater ID="rptUsers" runat="server">
    <HeaderTemplate>
        <table border="1">
            <tr>
                <th>ID</th>
                <th>Name</th>
                <th>Email</th>
            </tr>
    </HeaderTemplate>
    <ItemTemplate>
        <tr>
            <td><%# Eval("ID") %></td>
            <td><%# Eval("Name") %></td>
            <td><%# Eval("Email") %></td>
        </tr>
    </ItemTemplate>
    <FooterTemplate>
        </table>
    </FooterTemplate>
</asp:Repeater>

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        // 假设我们有一个名为 "Users" 的数据库表
        string connectionString = ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString;
        using (SqlConnection conn = new SqlConnection(connectionString))
        {
            conn.Open();
            string query = "SELECT ID, Name, Email FROM Users";
            SqlCommand cmd = new SqlCommand(query, conn);
            SqlDataReader reader = cmd.ExecuteReader();
            rptUsers.DataSource = reader;
            rptUsers.DataBind();
            reader.Close();
        }
    }
