How to Specify an IP Address for TcpClient to use

During development, we usually use localhost as the hostname, like the following

 Dim serverListener As New TcpClient("localhost", 8585)

I want the user to be able to enter their IP address via a TextBox instead, like

Dim serverListener As New TcpClient(textbox1.text, 8585)

However, this is not working for me. Any ideas? Thanks!

The form of the TcpClient constructor that accepts a string and an int parameter expects a hostname and a port, not an IP address.

You might want to use the TcpClient constructor that takes an IPEndPoint parameter instread. There is more information on the IPEndPoint class on MSDN, but in short it represents an IP address and a port number.

Perhaps this will help?

You can also use IPAdress.TryParse() to check if its a valid adress
