Example

[Visual Basic, C#, C++] The following example specifies the data buffer, an offset, a size, and SocketFlags for sending data to a connected Socket.

[Visual Basic, C#, C++] Note   This example shows how to use one of the overloaded versions of Send. For other examples that might be available, see the individual overload topics.

[Visual Basic] 
' Displays sending with a connected socket
' using the overload that takes a buffer, offset, message size, and socket flags.
Public Shared Function SendReceiveTest4(server As Socket) As Integer
    Dim msg As Byte() = Encoding.UTF8.GetBytes("This is a test")
    Dim bytes(255) As Byte
    Try
        ' Blocks until send returns.
        Dim i As Integer = server.Send(msg, 0, msg.Length, SocketFlags.None)
        Console.WriteLine("Sent {0} bytes.", i)
        
        ' Get reply from the server.
        server.Receive(bytes, 0, server.Available, SocketFlags.None)
        Console.WriteLine(Encoding.UTF8.GetString(bytes))
    Catch e As SocketException
