cs頁(yè)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(yuǎn)程服務(wù)器上的URL.
好了,小伙伴們是否有了新的認(rèn)識(shí)了呢,希望大家能夠喜歡。
