how to download music with asp.net
<p>I have an asp.net webform application. I want to have a button for downloading musics, so I write below code block :</p>

<pre><code>protected void Button1_Click(object sender, EventArgs e)
{
    string id_new;
    id_new = Session["selectedmusicID"].ToString();
    DataTable dt2 = new DataTable();
    dt2 = blm.selectMusic("sel_music", Convert.ToInt32(id_new));
    string test = dt2.Rows[0][9].ToString();
    Response.ContentType = "application/mp3";
    Response.AddHeader("Content-Disposition", dt2.Rows[0][9].ToString());
    Response.TransmitFile(Server.MapPath( dt2.Rows[0][9].ToString()));
    Response.End();
}
</code></pre>

<p>When I run this code and click on button it downloads the music.aspx page not mp3 file.I don't know what is my mistake.
Anyone can help me?</p>
