Restricting class creating only 3 objects

[User 3519179]

Use a Singleton-like approach. Make the constructor private and add a static method. In this method return a new instance of the class when a static counter is less than 3 (starting with 0). Then increment the counter. If the counter is >2 do what ever you like to do if the third instance is delivered. Small example: public class MyRestrictedClass { private static int instanceCounter = 0; private MyRestrictedClass() { //cool ctor stuff } public MyRestrictedClass GetNextInstance() { if(instanceCounter<=2) { instanceCounter++; return new MyRestrictedClass(); } throw new Exception("Maximum number of instances exceeded."); } } Best regards Jens

When in trouble, when in doubt, run in circles, scream and shout
