我有一个用户可以在其中下载文件的应用程序.我要在下载时打开新窗口，这意味着当用户单击下载按钮时，页面必须在另一页面上重定向，然后下载后便会开始.就像这个代码项目站点一样，当我们尝试下载任何文件时，它会将我们重定向到另一页上，然后开始下载.谁能帮我吗...??在此先感谢....

Just like this code project site, when we try on download any file it''ll redirect us on another page and then after download will start. Can any one help me out...?? Thanks in advance....
推荐答案
下载链接指向一个新文档.在该文档上，您将创建一个javascript函数，该函数可以将用户重定向到实际的可下载文件.
Download.aspx:
Download link points to a new document. On that document you create a javascript-function which location-href''s the user to the actual downloadable file.
Download.aspx:
<body onload="location.href='fileToDownload.zip'">
<p>Your download will start in a few seconds</p>
</body>
在下载图像的情况下，可以使用以下代码添加download.aspx:
In your case of downloading an image you can add a download.aspx with the following code:
protected void Page_Load(object sender, EventArgs e)
{
// Get the full pathname for imagefile
var imageFilename = Request.QueryString["imgName"];
var path = Server.MapPath("/Images/" + imageFilename)
// read the file
using (FileStream fs = File.OpenRead(path))
{
int length = (int)fs.Length;
byte[] buffer;
using (BinaryReader br = new BinaryReader(fs))
{
buffer = br.ReadBytes(length);
}
// Force browser to download rather than open the file in browser
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", String.Format("attachment;filename={0}", Path.GetFileName(path)));
Response.ContentType = "image/jpeg";
Response.BinaryWrite(buffer);
}
}
<body önload="location.href='download.aspx?imgFile=nicepicture.jpg'">
<p>Your download will start in a few seconds</p>
</body>
