发送端

Inherits System.Windows.Forms.Form
Private Sub Button1_Click(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles Button1.Click
Dim sendsocket As New Net.Sockets.Socket
(Net.Sockets.AddressFamily.InterNetwork,
Net.Sockets.SocketType.Stream, Net.Sockets.ProtocolType.Tcp)
'实例化socket
Dim ipendpiont As New Net.IPEndPoint
(Net.IPAddress.Parse("192.168.0.1"), 8888)'建立终结点
'OpenFileDialog1.ShowDialog()
Dim fs As New IO.FileStream("c:\p.doc",
IO.FileMode.OpenOrCreate, IO.FileAccess.Read)'要传输的文件
Dim fssize(fs.Length - 1) As Byte
Dim strread As New IO.BinaryReader(fs)'流处理要传输的文件
'fs.Read(fssize, 0, fssize.Length - 1)
strread.Read(fssize, 0, fssize.Length - 1)
sendsocket.Connect(ipendpiont)'连接远程计算机
sendsocket.Send(fssize)'发送文件
Label1.Text = fs.Length()
fs.Close()

receivesocket.Bind(hostipendpiont)
'建立远程计算机的的socket
receivesocket.Listen(2)'监听socket
End Sub
Private Sub Button1_Click(ByVal sender As Object,
ByVal e As System.EventArgs) Handles Button1.Click
Dim recfs As New IO.FileStream("p.doc",
