Answer 1

in the controller, you need to create a function that return a FileResult
in vb.net
Function img() As FileResult
Dim bmp As Bitmap = Nothing
Dim dll As New Chess.cChessBoard
dll.drawBoardPNG(bmp)
Dim imgStream As New IO.MemoryStream
bmp.Save(imgStream, ImageFormat.Png)
imgStream.Position = 0
Return File(imgStream.ToArray, "image/png")
End Function
in the view, you only need to call
<img src="/test/chess/img" />
