SQL Question

Download file stored in SQL database from C#

I have SQL database where I am storing user uploaded file.

I have created a

linkbutton
to download the file. On click of that link button I am calling below code. Unfortunately it is not working. Not event throwing any error.

I have stored filename, contentType and bytes as 3 columns in my SQL table

Response.Clear();
Response.Buffer = true;
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = contentType;
Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName);
Response.BinaryWrite(bytes);
Response.Flush();
Response.End();


What could be the issue? Or Any other way to achieve this?

UPDATE:

With same code and changes based on answer marked as correct, I did changes and it worked. Providing working code here for future reference of other users:

protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = Session["fileAttachment"] as DataTable;
string fileName = Convert.ToString(dt.Rows[0]["filename"]);
string contentType = Convert.ToString(dt.Rows[0]["contentType"]);
byte[] bytes = Convert.FromBase64String(Convert.ToString(dt.Rows[0]["bytearr"]));
Response.Clear();
Response.ClearHeaders();
Response.Buffer = true;
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = contentType;
Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName);
//Response.BinaryWrite(bytes); //
Response.BufferOutput = true;
Response.OutputStream.Write(bytes, 0, bytes.Length);
Response.Flush();
Response.End();
}


Added above code in new page and redirected to this page after created session

Answer

In my app this code working. I use it in new page. You need know what is extension of your file.

protected void Page_Load(object sender, EventArgs e)
        {
            string fullName = String.Empty;
            fileName = Request.Params["nazwa"];
            ext=Request.Params["ext"];
            fullName = fileName + "." + ext;
            byte[] bts = GetAttachment(dokumentDaneId);
            Response.Clear();
            Response.ClearHeaders();
            Response.ContentType = ContentType["."+ext].ToString();
            Response.AddHeader("content-disposition", "attachment; filename=" + fullName);
            Response.BufferOutput = true; ;
            Response.OutputStream.Write(bts, 0, bts.Length);
            Response.End();
        }

private static IDictionary<string, string> ContentType = new Dictionary<string, string>(StringComparer.InvariantCultureIgnoreCase) {
