Button的OnClick事件如果实现如()下载文件效果

[qq2013]

如
<asp:Button ID="saveButton" runat="server" Text="下载" OnClick="saveButton_Click" />

protected void saveButton_Click(object sender, EventArgs e)
{
}
中如何实现
<a href='文件路径' ></a>的下载效果!

Response.ContentType = "application/octet-stream";
Response.WriteFile("" + path + "");

要下载时都是调用一个页面,页面page_load写这段代码就ok了

protected void saveButton_Click(object sender, EventArgs e)
{
Response.Clear();
//Response.Charset = Encoding.Unicode.ToString();
Response.Charset = "gb-2312";
Response.Buffer = true;
//Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
Response.AppendHeader("Content-Disposition", "attachment;filename=" + downloadFilename);

Response.ContentType = "application/unknown";

Response.WriteFile(文件路径);
}

完全可以,不过路径中最后面一定要加上文件的名字.

[wjn161]

 Response.Write("<script> window.location.href('xx.doc');</script>");

这样做可行，但不好。期待有更好的方法!

不是重新打开了一个页面啦!

[wuyq11]

string path = Server.MapPath("~/") + "";
Response.AppendHeader("Content-Disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode(Name, System.Text.Encoding.GetEncoding("utf-8")) + "." + AttachmentExt);
Response.ContentType = "application/octet-stream";
Response.WriteFile("" + path + "");
Response.End();
