TcpClient - 绑定/使用特定的IP。 （vb.net） [英] TcpClient - bind to/use a specific IP. (vb.net)
问题描述
大家好，
我在尝试绑定到特定的IP地址时遇到了一些麻烦。
代码：
私有mobjClient作为TcpClient
mobjClient =新TcpClient（IPAddress.Parse（" 10.16.104.87"）。ToString，
8892）
mobjClient.GetStream.BeginRead（marData，0,1024，AddressOf DoRead，
什么都没有）
上面的代码与代码的其余部分完美配合 - 但
我想弄清楚的是如何使用特定的IP来连接
。
我有4个IP地址，我想使用3和3。一。我怎么能告诉
使用那个IP的代码？
目前我已经尝试过：
mobjClient.Client。绑定（新
IPEndPoint（IPAddress.Parse（" 10.24.36.22"），8892））
但这不起作用。任何人都可以帮助我吗？

Hi all,
I got into some trouble trying to bind to a specific IP address.
Code:
Private mobjClient As TcpClient
mobjClient = New TcpClient(IPAddress.Parse("10.16.104.87").ToString ,
8892)
mobjClient.GetStream.BeginRead(marData, 0, 1024, AddressOf DoRead,
Nothing)
The above code works perfectly along with the rest of the code - but
what I am trying to figure out is how to use a specific IP to connect
from.
I have 4 IP addresses and I want to use a the "3" one. How can I tell
the code to use that one IP?
Currently I have tried with:
mobjClient.Client.Bind(New
IPEndPoint(IPAddress.Parse("10.24.36.22"), 8892))
But that doesnt work. Can anyone help me out here?

列出网络接口和IP地址：
Imports System.Net
进口系统。 Net.NetworkInformation
''...
Dim NInterfaces = NetworkInterface.GetAllNetworkInterfaces
对于NInterfaces中的每个NInterface
Dim Props = NInterface.GetIPProperties（）
Dim Addresses = Props.UnicastAddresses
Debug.Print （NInterface.Description）
地址中的每个地址
Debug.Print（""& Address.Address.ToString）

对于TCPClient：

" Address.Address"就是你之前在内环中看到的。

嗨阿明，
感谢您的回复。
我想找到所有IP地址的最简单方法是：
Dim ipE As IPHostEntry = Dns。 GetHostEntry（Dns.GetHostName（））
Dim IpA（）As IPAddress = ipE.AddressList
现在IpA包含数组中的所有IP地址。但这是另一个
的故事！
主要问题是我想使用特定的
连接到TCP服务器IP地址。 （防火墙问题）我只能让TcpClient
使用我的Windows机器上的第一个可用IP地址。我有4个
IP'，并希望TcpClient使用3. one。我无法工作
。
因此，当我遇到套接字编码时，我花了几个小时搜索网络
代替。现在我能够绑定到特定的IP - 见下文：
私有ClientSocket作为套接字
ClientSocket =新套接字（AddressFamily.InterNetwork） ，
SocketType.Stream，ProtocolType.Tcp）
Dim endpoint As New IPEndPoint（IPAddress.Parse（" 10.16.104.87"），8892）
Dim bindaddress As New IPEndPoint（IPAddress.Parse（" 10.24.36.22"），0）
ClientSocket.Bind（bindaddress）
ClientSocket.BeginConnect（端点，AddressOf已连接，无）
它现在正在运行。 ; o）

Hi Armin,
Thank you for your reply.
I guess the easiest way to find all IP addresses are like:
Dim ipE As IPHostEntry = Dns.GetHostEntry(Dns.GetHostName())
Dim IpA() As IPAddress = ipE.AddressList
Now IpA contains all IP addresses in a array. But that is another
story!
The main issue was that I wanted to connect to a TCP server using a
specific IP address. (firewall issues) I could only have the TcpClient
use the first available IP address on my Windows machine. I have 4
IP''s and wanted the TcpClient to use the 3. one. That I could not get
to work.
So I spend hours searching the net when I came across Socket coding
instead. Now I am able to bind to a specific IP - see below:
Private ClientSocket As Socket
ClientSocket = New Socket(AddressFamily.InterNetwork,
SocketType.Stream, ProtocolType.Tcp)
Dim endpoint As New IPEndPoint(IPAddress.Parse("10.16.104.87"), 8892)
Dim bindaddress As New IPEndPoint(IPAddress.Parse("10.24.36.22"), 0)
ClientSocket.Bind(bindaddress)
ClientSocket.BeginConnect(endpoint, AddressOf Connected, Nothing)
And it is now working. ;o)
