文件下载不可逾越的问题：无法调用IE

[terencegan]

请教各位老大:
我做文件下载，弹出"文件下载对话框"，可以保存文件；但是当打开文件时，IE不是弹出一个新IE，而是利用桌面上已经打开的IE，甚至可以会促使页面关闭，请高人指点，解决问题，马上给分！

hyperlink.aspx文件，有hyperlinke控件
有如下代码:
protected void Page_Load(object sender, EventArgs e)
{

if (!this.IsPostBack)
{

this.HyperLink1.NavigateUrl = "download.aspx";
this.HyperLink1.Target = "_blank";
this.HyperLink1.Text = "测试文件打开";
this.HyperLink1.Target = "_blank";
}
}
download.aspx.cs文件，有如下代码：
protected void Page_Load(object sender, EventArgs e)
{

if (!this.IsPostBack)
{
try
{

string path = Server.MapPath("linshilanmu3.jpg");
if (!System.IO.File.Exists(path))
{

this.Page.Response.End();
}

System.IO.FileInfo file = new System.IO.FileInfo(path);

this.Page.Response.Clear();
this.Page.Response.Buffer = false;
this.Page.Response.AddHeader("Content-Disposition", "attachment;filename=" + file.Name);
this.Page.Response.AddHeader("Content-Length", file.Length.ToString());
#region//文件下载类型
string filename = "linshilanmu3.jpg";
string strFilePostfix = filename.Substring(filename.Length - 4, 4).ToLower();
if (strFilePostfix == ".asf")
this.Response.ContentType = "video/x-ms-asf";
else if (strFilePostfix == ".avi")
this.Response.ContentType = "video/avi";
else if (strFilePostfix == ".doc")
this.Response.ContentType = "application/msword";
else if (strFilePostfix == ".zip")
this.Response.ContentType = "application/zip";
else if (strFilePostfix == ".xls")
this.Response.ContentType = "application/vnd.ms-excel";
else if (strFilePostfix == ".avi")
this.Response.ContentType = "video/avi";
else if (strFilePostfix == ".gif")
this.Response.ContentType = "image/gif";
else if (strFilePostfix == ".jpg" || strFilePostfix == ".jpeg")
this.Response.ContentType = "image/jpeg";
else if (strFilePostfix == "audio/wav")
this.Response.ContentType = "audio/wav";
else if (strFilePostfix == ".mpg" || strFilePostfix == ".mpeg")
this.Response.ContentType = "video/mpeg";
else if (strFilePostfix == ".rtf")
this.Response.ContentType = "application/rtf";
else if (strFilePostfix == ".htm" || strFilePostfix == ".html")
this.Response.ContentType = "text/html";
else if (strFilePostfix == ".txt")
this.Response.ContentType = "text/plain";
else
this.Response.ContentType = "application/octet-stream";
#endregion
this.Page.Response.WriteFile(file.FullName);
this.Response.Flush();

this.Page.Response.End();
}
catch
{

this.Page.Response.Write("附件不存在或者已经被删除！");
}

}
}

[真相重于对错]

try
Response.Write("<script>window.open(\"download.aspx\")</script>")

[terencegan]

try
Response.Write("<script>window.open(\"download.aspx\")</script>")
，这个方法还是无法解决，不过谢谢您的关注

IE7修正了这个 bug

[真相重于对错]

那句你写在哪呢？？
你应该用linkbutton代替this.HyperLink1
然后再linkbutton的click事件里写

[terencegan]

protected void LinkButton1_Click(object sender, EventArgs e)
{
this.Response.Write("<script>window.open('download.aspx')</script>");
}

也不能解决啊

下载页面也做过不少，不过没见过这种问题，如果实在不行，你可以单独再做个跳转的页面，下载时先在新窗口中打开这个页面，在这个页面中再跳转到download.aspx页面实现下载

已经定义this.HyperLink1.Target = "_blank";应该没有问题啊，有的浏览器倒是保存或取消后出现空白页面，不知搂主如何解决的？
