ASPX page code:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="GetPictureByUrl.aspx.cs" Inherits="HoverTreeMobile.GetPictureByUrl" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title> Download the picture to the server according to the website </title>
</head>
<body>
<form id="form1" runat="server">
<div>
Image website: <br /><asp:TextBox runat="server" ID="textBoxImgUrl" Width="500" Text="/hvtimg/201508/cnvkv745.jpg" />
<br /> <asp:Button runat="server" ID="btnImg" Text=" Download " OnClick="btnImg_Click" />
<br /><asp:Image runat="server" ID="hvtImg" />

</body>
</html>
cs page code:
using System;
namespace HoverTreeMobile
{
public partial class GetPictureByUrl : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnImg_Click(object sender, EventArgs e)
{
try
{
System.Net.WebClient m_hvtWebClient = new System.Net.WebClient();
string m_keleyiPicture = Server.MapPath("/hovertreeimages/keleyi.jpg");
// Download files based on URL
m_hvtWebClient.DownloadFile(textBoxImgUrl.Text, m_keleyiPicture);
hvtImg.ImageUrl = "/hovertreeimages/keleyi.jpg";
ltlTips.Text = string.Empty;
}
catch(Exception ex)
{
ltlTips.Text = ex.ToString();
}
}
}
}
In addition, I would like to share with you the idea of the core method of downloading pictures under 1
using System.Net;
WebClient myclient = new WebClient();
myclient.DownloadFile("http://www.baidu.com/img/sslm_logo.gif",@"c:\baidu.gif");
DownloadFile In the method address Is the remote server you want to put together URL.
Ok, do you have a new understanding? I hope you can like it.
