How to convert a socket data buffer into pictures.

[Guest]

I have a c# client application that connects to a network socket. When
connected, the listener sends a network stream containing bitmap, jpeg, data
from a file nominated by the client. The client application (also c#)
receives the data into a byte[] array. I want to pass the byte[] array
directly to a picture control on the form. I can't find a way to do this so I
used a file stream and write the byte[] array to a file, and then pass that
pathname into the Image.LoadFile(pathname) method and then assign the image
to the picture, as in Picture.Image = RuntimeImage.

This works but having to use an interface file to get the data into the
picture control is not ideal. Is it possible somehow to massage the byte[]
array I got from the NetworkStream directly to the Picture control?

I haven't tested this and not positive that it would work, but can't you use
the share function Image.FromStream(Stream) as Image. Just pass in your
stream.

This is the correct way.

Thanks guys.

I tried that and ended up with this chunk of code:

TcpClient S = new TcpClient("localhost", 50001);
NetworkStream NS = S.GetStream();
Picture.Image = Image.FromStream(NS);
Picture.Refresh();
NS.Close();
S.Close();

It works 100% fine. I could receive image files (bmp/jpg) in size from 4k
upto 1.6Mb and they displayed perfectly.

Hello,

First, sorry for my English.

I have the same problem, with the NET CompactFramework. With
NETCF the Image.FromFile method is not available.
Have you other solutions for these problem?

Thank you
