C#實現(xiàn)把圖片下載到服務(wù)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(jù)網(wǎng)址把圖片下載到服務(wù)器/title> /head> body> form id="form1" runat="server"> div> 圖片網(wǎng)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(jù)網(wǎng)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方法里的address就是你要拼成的遠程服務(wù)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。
