ASP.NET Eval DataBinding C#

Question

你可以轻松地做到:

        <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>

但如果我想通过两个Querystrings？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>

如何在"Eval DataBinding"中为URL设置两个或更多查询字符串？

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>
