C#實現把圖片下載到服務器代碼
ASPX頁面代碼：
<%@ 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>根據網址把圖片下載到服務器</title> </head> <body> <form id="form1" runat="server"> <div> 圖片網址：<br /><asp:TextBox runat="server" ID="textBoxImgUrl" Width="500" Text="/hvtimg/201508/cnvkv745.jpg" /> <br /> <asp:Button runat="server" ID="btnImg" Text="下載" OnClick="btnImg_Click" /> <br /><asp:Image runat="server" ID="hvtImg" /> <br /> <asp:Literal runat="server" ID="ltlTips" /> </div> </form> </body> </html>
cs頁面代碼：
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");
//根據網址下載文件
m_hvtWebClient.DownloadFile(textBoxImgUrl.Text, m_keleyiPicture);
hvtImg.ImageUrl = "/hovertreeimages/keleyi.jpg";
ltlTips.Text = string.Empty;
}
catch(Exception ex)
{
ltlTips.Text = ex.ToString();
}
}
}
}
另外給大家分享一下下載圖片的核心方法的思路
using System.Net;
WebClient myclient = new WebClient();
myclient.DownloadFile("http://www.baidu.com/img/sslm_logo.gif",@"c:\baidu.gif");
DownloadFile方法裡的address就是你要拼成的遠程服務器上的URL.
好了，小伙伴們是否有了新的認識了呢，希望大家能夠喜歡。
