不显示ASP.NET Datalist图像

Question

我正在使用Datalist在文件夹中显示图像。代码如下：

<div> 
    <asp:DataList ID="DataList1" runat="server" RepeatColumns="3"> 
     <HeaderTemplate> 
     </HeaderTemplate> 
     <ItemTemplate> 
      <img src = "<%# Container.DataItem %>" /> 
     </ItemTemplate> 
     <FooterTemplate> 
     </FooterTemplate> 
    </asp:DataList> 
</div> 

后面的代码：

protected void Page_Load(object sender, EventArgs e) 
    { 
     string[] list = Directory.GetFiles(Server.MapPath("sony")); 

     List<string> aList = new List<string>(); 
     foreach (var rec in list) 
     { 
      aList.Add(rec); 
     } 
     DataList1.DataSource = aList; 
     DataList1.DataBind(); 
    } 

它不显示图像。请帮助

Answer 1

protected void Page_Load(object sender, EventArgs e) 
{ 
    if (!IsPostBack) 
    { 
     string[] list = Directory.GetFiles(Server.MapPath("sony")); 

     var aList = from fileName in Directory.GetFiles(Server.MapPath("sony")) 
        select string.Format("/sony/{0}", Path.GetFileName(fileName)); 

     DataList1.DataSource = aList; 
     DataList1.DataBind(); 
    } 
}
