Asp.net hyperlink to download the TEXT file, instead of directly opening it in IE, asp. nettext

Problem description: a text file is generated in the background and provided to the user for download through a hyperlink. Click the hyperlink to download the Excel file. However, the text file will be opened directly, rather than the download window will pop up.

Solution: Change HyperLink to LinkButton. In the Click event, use a file stream to write text files.

Key code:

 1 protected void Button1_Click(object sender, EventArgs e) 2 { 3     string sFileName = System.IO.Path.GetRandomFileName(); 4     string sGenName = "Friendly.txt"; 5  6     //YOu could omit these lines here as you may 7     //not want to save the textfile to the server 8     //I have just left them here to demonstrate that you could create the text file  9     using (System.IO.StreamWriter SW = new System.IO.StreamWriter(10            Server.MapPath("TextFiles/" + sFileName + ".txt")))11     {12         SW.WriteLine(txtText.Text);13         SW.Close();14     }15 16     System.IO.FileStream fs = null;17     fs = System.IO.File.Open(Server.MapPath("TextFiles/" + 18              sFileName + ".txt"), System.IO.FileMode.Open);19     byte[] btFile = new byte[fs.Length];20     fs.Read(btFile, 0, Convert.ToInt32(fs.Length));21     fs.Close();22     Response.AddHeader("Content-disposition", "attachment; filename=" + 23                        sGenName);24     Response.ContentType = "application/octet-stream";25     Response.BinaryWrite(btFile);26     Response.End();27 }
