Sending image file through socket

Question

I am a beginer in .net programming. I want to know how to transfer image through socket. For example if i want to transfer texts i.e strings through socket, i'll do something like this:

VB

Dim toSend As Byte() = System.Text.Encoding.ASCII.GetBytes("This is a sample text that i want to send")
Dim myNWS As NetworkStream = connectedTCPClient.GetStream()

myNWS.Write(toSend, 0, toSend.Length)

Whereas, if i want to transfer image file through tcpclient networkstream just like that of string, how do i do this?
I mean something like this:

VB

Dim img As Image = Image.FromFile("C:\myIMG.png")

then how do i get the byte encoding of the image so that i can transfer it to external socket.
Something like

VB

Dim imgbyte As Byte() = Encoding.GetBytes(img)

but ASCII encoding type only support strings. How do i turn this image to byte?

Solution 1

It is better to transfer your data as chunks as there is a limit to how much you can send across the tcp connection.

Check my article (in c# I'm afraid but you can compile it and use it in vb.net): WCF Killer[^]

Thanks everybody. I found a solution how i can get the bytes of any file including pictures e.t.c.
The method is

Dim imgPath As String = "C:\MyImg.jpg"

Dim bytes As Byte() = IO.File.ReadAllBytes(imgPath)
