ASP.NET2.0显示文件夹下全部图片_[Asp.Net教程]

ASP.NET2.0显示文件夹下全部图片_[Asp.Net教程]
1.以下目录有若干图片（都是大图片）


2.在页面展现效果图



3.后台代码



using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Lifetime;
using System.IO;

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
DirectoryInfo imagesfile = new DirectoryInfo(Server.MapPath("./images"));
DataList1.DataSource = imagesfile.GetFiles("*.jpg");
DataList1.DataBind();


}

}



前台代码：


<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>





遍历文件夹下所有图片 http://blog.csdn.net/21aspnet 清清月儿

说明：如果大家想生成真正的缩略图就要在另个页面生成
ImageUrl=’<%#"AAA.aspx 取得生成的结果即可。可参考以下代码：

Example: SimpleImageHandler.ashx
<%@ WebHandler Language="C#" Class="SimpleImageHandler" %>

using System;
using System.Drawing;
using System.Drawing.Imaging;
using System.IO;
using System.Web;
using System.Web.Caching;

public class SimpleImageHandler : IHttpHandler {

public void ProcessRequest(HttpContext context)
{
// Load image.
Bitmap bmap = new Bitmap(@"C:\Temp\TEST.JPG");

// You could do something here, e.g. add some texts to image.

// Send back image.
context.Response.ContentType = "image/jpeg";
context.Response.BufferOutput = false;
bmap.Save(context.Response.OutputStream, ImageFormat.Jpeg);
}

public bool IsReusable
{
get
{
return false;
}
}

}
