i tried

Response.BinaryWrite(fileData);

Answer 1

You need also to set the content type:

Response.ContentType = "application/octet-stream";

Answer 2

Try this:

Response.Clear();
Response.AppendHeader("content-disposition", "attachment; filename=fileToDownload");
Response.ContentType = "application/octet-stream";
Response.BinaryWrite(fileData);
Response.Flush();
Response.End();
