利用Socket 可以编写一个 向 客户端传送 时间的 一个程序，现在他还只能向
固定的客户端 传送时间，我打算过几天 写一个 可以向 浏览器传送 时间的一个程序
请大家随时注意我的站点的更新情况。。。
Imports System
Imports System.Net
Imports System.Net.Sockets
Imports System.Text
Public Class DateTimeServer
Public Shared Sub temp()
System.Console.WriteLine("hello")
Console.Writeline("Hello\n")
End Sub
Public Shared Sub Main()
Dim now As Date
Dim strDateLine As String
Dim ASCII As Encoding = Encoding.ASCII
Dim tcpl As New TCPListener(13) 'listen on port 13
tcpl.Start()
Console.WriteLine("Waiting for clients to connect")
Console.WriteLine("Press Ctrl+c to Quit...")
While (True)
' Accept will block until someone connects
Dim s As Socket = tcpl.Accept()
' Get the current date and time then concatenate it
' into a string
now = DateTime.Now
strDateLine = now.ToShortDateString() + " " + now.ToLongTimeString()
' Convert the string to a Byte Array and send it
Dim byteDateLine() As Byte = ASCII.GetBytes(strDateLine.ToCharArray())
s.Send(byteDateLine, byteDateLine.Length, 0)
Console.WriteLine("Sent " + strDateLine)
End While
End Sub
End Class
