How to restrict get; setter; to get only inside c# asp net classes

Lets say you have a get, set property inside a class say IP

public String IP { get; }

When I specify get only I wont be able to set the property even inside the class itself. e.g

this.IP = "127.0.0.1";

Property or indexer 'IP' cannot be assigned to -- it is readonly 

Solution, just type private keyword with set property like this

public String IP { get; private set; }

All done
