的TcpListener：如何在所有接口上的特定端口听呢？ [英] TcpListener: How to listen on specific port on all interfaces?

问题描述

有三个重载构建一个 的TcpListener ：

There are three overloads for constructing a TcpListener:

• 公开的TcpListener（INT端口）; （过时的）
• 公开的TcpListener（IPEndPoint localEP）
• 公开的TcpListener（ip地址localaddr，INT口）

• public TcpListener(int port); (obsolete)
• public TcpListener(IPEndPoint localEP)
• public TcpListener(IPAddress localaddr, int port)

我的需要的监听某个特定的端口，但在所有可用的接口。这里的已可用过载要做到这一点，但它被标记为过时。

i want to listen on a particular port, but on all available interfaces. There was an overload available to do that, but it's been marked as obsolete.

什么是新的preferred /非过时的方式与所有接口上的特定端口的 的TcpListener 在.NET？

What is the new preferred/non-obsolete way to listen on a particular port on all interfaces with a TcpListener in .NET?

有关乐于助人的缘故，一个 IPEndPoint 是：

For helpfulness sake, an IPEndPoint is:

public IPEndPoint(
    IPAddress address,
    int port
)

这是第3次超载是什么。而一个 ip地址 需要，因为它的构造函数：

which is what the 3rd overload is. And an IPAddress takes, as its constructor:

• 在字节[]
• 的的Int64
• 在字节[]和的Int64

• a byte[]
• an Int64
• a byte[] and an Int64

推荐答案

只是绑定到<一个href="http://msdn.microsoft.com/en-us/library/system.net.ipaddress.any.aspx"><$c$c>IPAddress.Any - 这是多么这通常是......不知道，但它可能是你需要绑定到<一个href="http://msdn.microsoft.com/en-us/library/system.net.ipaddress.ipv6any.aspx"><$c$c>IPAddress.IPv6Any了。

Just bind to the IPAddress.Any - that's how this is usually done... not sure but it could be that you need to bind to IPAddress.IPv6Any too.

这<一href="http://stackoverflow.com/questions/507254/tcplistener-listen-on-every-address-including-gprs-ip-address/507277#507277">SO帖子建议您绑定到每个IP addresse明确 - 这<一href="http://stackoverflow.com/questions/436778/send-broadcast-message-from-all-network-adapters/436898#436898">SO帖子对如何获得code所有IP ...不会忽略

This SO post suggests that you bind to every IP addresse explicitly - and this SO post has code on how to get all IP adresses...

从 MSDN ：

如果你不关心它的本地地址分配，指定 IPAddress.Any 的localaddr参数和基础服务供应商将分配最合适的网络地址。

If you do not care which local address is assigned, specify IPAddress.Any for the localaddr parameter, and the underlying service provider will assign the most appropriate network address.

从 MSDN ：

IPAddress.Any 的现场

提供指示该服务器应该监听客户端活动在所有网络接口的IP地址。

Provides an IP address indicating that the server should listen for client activity on all network interfaces.
