推荐答案

<asp:ListView id="MyListView" runat="server">
    <ItemTemplate>
        <asp:Label ID="MyLabel" runat="server" Text='<%#Eval("Name")%>' />
    </ItemTemplate>
</asp:ListView>

protected void Page_Load(object sender, EventArgs e)
{
    MyListView.DataSource = new List<MyData> { new MyData { Name = "John" }, new MyData { Name = "David" } };
    MyListView.DataBind();

    foreach (ListViewDataItem item in MyListView.Items)
    {
        Label l = (Label)item.FindControl("MyLabel");
        l.Text = l.Text.ToUpper();
    }
}
