求助 前台调用后台代码的问题
根据数据库的值判断Reperter中是否显示图片，代码如下，报错RepairInfolist.IsShowEditButtion(string)最匹配的重载方法具有一些无效参数,问题出在什么地方，请教下。前台代码：
<asp:Repeater ID="Repeater1" runat="server" >
<ItemTemplate >
<div id="publish_user" class="publish_user">
<div id="publish_user_top" class="publish_user_top ">
<div id="user" class="user">
<asp:Label ID="lbUserName" runat="server" Text='<%# Eval("Name")%>'></asp:Label>
</div>
<div id="publish_content" class="publish_content">
<div id="publish_content_top" class="publish_content_top"></div>
<asp:Label ID="lbReplyText" runat="server" Text='<%# Eval ("text") %> '></asp:Label>
</div>
</div>
<div id="user_bottom" class="user_bottom">
<asp:Label ID="lbReplyTime" runat="server" Text='<%# Bind("Create_time") %>'></asp:Label>
</div>
<div id="publish_content_bottom" class="publish_content_bottom">
<asp:Image ID="imgReplyReply" runat="server" ImageUrl="~/Image/reply.gif" />
<asp:Image ID="imgReplyReplya" runat="server" ImageUrl="~/Image/reply_a.gif" />
<asp:Image ID="imgReplyEdit" runat="server" ImageUrl="~/Image/edit.gif" Visible = '<%# IsShowEditButtion(Eval("user_id")%>' />
<asp:Image ID="imgRelyUp" runat="server" ImageUrl="~/Image/p_up.gif" />
</div>
</div>
</ItemTemplate>
</asp:Repeater>
后台代码：
public bool IsShowEditButtion(string str)
{
string Corrent = Session [Session .SessionID ].ToString ();
if (Corrent == str)
{
return true ;
}
else
{
return false ;
}
}
