如果在程序里把IP改成 127.0.0.1， 而本机的网卡IP不做任何改动，运行程序不会报错。
请问这是什么原因？求帮助！
下面是程序代码：
Imports System.Net
Imports System.Net.Sockets
Public Class Form1
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim serSock As New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
Dim LocalIp As IPAddress = IPAddress.Parse("192.168.0.191")
Dim endPoint As EndPoint = New IPEndPoint(LocalIp, 5000)
serSock.Bind(endPoint)
serSock.Listen(10)
End Sub
End Class
如果把 Dim LocalIp As IPAddress = IPAddress.Parse("192.168.0.191") 改成127.0.0.1 则没有问题。
