 ## Remarks  
- This constructor allows you to specify the local IP address and port number on which to listen for incoming connection attempts. Before calling this constructor you must first create an <xref:System.Net.IPAddress> using the desired local address. Pass this <xref:System.Net.IPAddress> to the constructor as the `localaddr` parameter. If you do not care which local address is assigned, specify <xref:System.Net.IPAddress.Any?displayProperty=nameWithType> for the `localaddr` parameter, and the underlying service provider will assign the most appropriate network address. This might help simplify your application if you have multiple network interfaces. If you do not care which local port is used, you can specify 0 for the port number. In this case, the service provider will assign an available port number between 1024 and 5000. If you use this approach, you can discover what local network address and port number has been assigned by using the <xref:System.Net.Sockets.TcpListener.LocalEndpoint%2A> property.
