Please check that your browser is preventing to download the file. Secondly, debug the code whether client.IsConnected returns true. Thirdly, check if you have conent in ur StreamReader variable.

private void download (DataTable dt)
{
Byte[] bytes = (Byte[])dt.Rows[0]["Data"];
Response.Buffer = true;
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = dt.Rows[0]["ContentType"].ToString();
Response.AddHeader("content-disposition", "attachment;filename="
+ dt.Rows[0]["Name"].ToString());
Response.BinaryWrite(bytes);
Response.Flush();
Response.End();
}
