ASP.NET 评估数据绑定 C#

Question

您可以轻松做到：

        <asp:Repeater ID="rptCityFriends" runat="server" OnItemDataBound="rptFriendsContainer_DataBound">
                <ItemTemplate>
                            <asp:ImageButton ID="imgThumb" runat="server" PostBackUrl='<%# Eval("FBUsuarioID","~/Friends.aspx?friendID={0}") %>' ImageUrl='<%# Eval("FBAvatarUsuario") %>' CssClass="imgThumbs" />
                </ItemTemplate>
            </asp:Repeater>

但是如果我想传递两个查询字符串？IE：

            <asp:Repeater ID="rptCityFriends" runat="server" OnItemDataBound="rptFriendsContainer_DataBound">
                    <ItemTemplate>
                                <asp:ImageButton ID="imgThumb" runat="server" PostBackUrl='<%# Eval("FBUsuarioID","FBNomeUsuario","~/Friends.aspx?friendID={0}&nUser={1}") %>' ImageUrl='<%# Eval("FBAvatarUsuario") %>' CssClass="imgThumbs" />

                    </ItemTemplate>
                </asp:Repeater>

如何将两个或多个查询字符串设置为“Eval DataBinding”中的 URL？

Answer 1

使用String.Format()，即

<asp:Repeater ID="rptCityFriends" runat="server" OnItemDataBound="rptFriendsContainer_DataBound">
    <ItemTemplate>
          <asp:ImageButton ID="imgThumb" runat="server" PostBackUrl='<%# String.Format("~/Friends.aspx?friendID={0}&nUser={1}", Eval("FBUsuarioID"), Eval("FBNomeUsuario")) %>' ImageUrl='<%# Eval("FBAvatarUsuario") %>' CssClass="imgThumbs" />
    </ItemTemplate>
</asp:Repeater>
