asp.net保存网上图片到服务器的实例

本文讲述的是根据一个图片的url地址，保存图片到asp.net服务器端的实现方法。

建立GetImage.aspx页面，代码如下：

				?

									<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="GetImage.aspx.cs" Inherits="KeleyiTestWeb.KImage.GetImage" %>

									<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

									<html xmlns="http://www.w3.org/1999/xhtml">

									<head runat="server">

									<title>asp.net保存网上图片到服务器-KWS</title>

									</head>

									<body>

									<form id="form1" runat="server">

									<div>

									要获取的图片的网址：<asp:TextBox runat="server" ID="tbPicUrl" Text="http://keleyi.com/image/a/ipkvp9eq.jpg" Width="300" />

									<asp:Button Text="保存" runat="server" ID="btnSave" onclick="btnSave_Click" /><br /> 获取成功后在保存到服务器的同时将会显示在下面

									<br /><asp:Literal runat="server" ID="ltlTips" />

									<br /><asp:Image runat="server" ID="imgDownload" />

									</div>

									</form>

									<div>本例子请参考：<a href="http://keleyi.com/a/bjac/4yiwpvt0.htm" target="_blank">http://keleyi.com/a/bjac/qwcsgskp.htm</a> </div>

									</body>

									</html>

GetImage.aspx.cs的代码如下：

				?

									/*

									参考：http://keleyi.com/a/bjac/qwcsgskp.htm

									*/

									using System;

									using Keleyi.KFrame.KImage;

									namespace KeleyiTestWeb.KImage

									{

									public partial class GetImage : System.Web.UI.Page

									{

									protected void Page_Load(object sender, EventArgs e)

									{

									}

									protected void btnSave_Click(object sender, EventArgs e)

									{

									string m_fileName = DateTime.Now.ToFileTime().ToString() + ".jpg";

									string m_saveName = "download/" + m_fileName;

									string m_savePath = Server.MapPath(m_saveName);

									if (KeleyiImgDownloader.DownloadPicture(tbPicUrl.Text, m_savePath, -1))

									{

									ltlTips.Text = "获取成功";

									imgDownload.ImageUrl = m_saveName;

									}

									else

									ltlTips.Text = "获取失败";

									}

									}

									}
