我有以下代码

    <br />
    <br />
    <br />
    <br />
    <br />
    <br />
</div>
</form>

当我尝试将某些变量传递到下一页时，它们没有被传递。有人告诉我，我的URL字符串中没有说明＆符号和黑色。最好的方法是什么？

谢谢

您需要对查询参数进行url编码：

<asp:HyperLink 
    ID="Firstlisting" 
    runat="server" 
    Text='<%# Eval("Firstlisting") %>' 
    NavigateUrl='<%# string.Format("~/website1/Default3.aspx?firstlisting={0}", Server.UrlEncode((string)Eval("Firstlisting"))) %>' 
/>

传递URL字符串中的值
