Answer 1

// You will need to figure out the correct content type based on the file type 
// for example image/jpeg for jpeg files
Response.ContentType = ...;
var cd = new ContentDisposition()
{
    Inline = true,
    FileName = FileName
};
Response.AppendHeader("Content-Disposition", cd.ToString());
Response.OutputStream.Write(FileData, 0, FileData.Length);
