嗨每一个

我正在尝试当用户点击图像按钮，这是一边的数据列表，我想在存储在文件夹（解决方案资源管理器）中的数据列表中显示所选图像

请帮帮我

进展中的Thanx



我的代码

 <   asp：DataList     ID   =  dlBrands < span class =code-attribute>   runat   =  server    onitemcommand   =   dlBrands_ItemCommand >  
 <   ItemTemplate  >  
 <   asp：Image     ID   =  imgBrandImages    runat   =  server   高度  =  100px   宽度  =  200px     ImageUrl   ='  <％ #Bind（ 名称，  〜// UploadedFiles / {0}）％> '    /  >  
 <   / ItemTemplate  >  
 <   / asp：DataList  >  

我的图片按钮

< asp：ImageButton ID =   imgbtnView runat =   server ImageUrl =   images / add.png 
 onclick =   imgbtnView_Click /> 

代码背后

  string  filename = Path.GetFileName（upBrandImages.PostedFile.FileName）; 
  if （filename！=  ）
 {
 upBrandImages.SaveAs（Server.MapPath（ 〜// UploadedFiles // + filename））; 
 BindDataList（）; 
} 
  else  
 {
 Response.Write（ 请选择图像）; 
 
} 

文件上传

 <   asp：FileUpload     ID   =  upBrandImages    runat   =  server    /  >  

解决方案

使用System.IO检索图像名称并将该集合对象绑定到datalist。
