I am new to C# and have a difficulty with the code structure. My application has:
GUI with button
Show my Ethernet IP. When user clicks this button PC's IP address is displayed.
ModbusTCPSlaveMachine. Within this class I create
TCPListenterand supply it with PC's Ethernet IP address.
In both cases I get local IP address using the same method
GetAllLocalIPv4. Right now I have 2 copies of this method in the code (in classes
ModbusTCPSlaveMachine) which is not good I guess. For example, in Python I would simply place the method in some utility module. I am aware that methods cannot be located directly in the namespace in C# while don't quite understand why.
The option I can think of is to place this function in a separate class - some utility class containing a single method (based on Python experience). Not sure if this is reasonable solution in C# beacuse this utility class looks like a meaningless container to me.
How can/should I solve the problem?
