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:Image runat="server" ID="imgDownload" />
</div>
</form>

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";www.9ask.cn/xiamen/
}
}
}
这里用到类KeleyiImgDownloader,在KFrame项目中建立,代码请下载项目的源代码
