hi yuriy you can use a foreach statement or a for loop for that matter with collections ie types that implement IEnumerable interface so you can have an array(as vulpes has mentioned) or a List etc which contains the objects of your class and iterate over it using foreach statement

Vulpes · Answer

foreach only works with enumerable collections such as arrays lists or even strings (collections of chars). Also the foreach iteration variable ('i' in your example) is read-only; in other words you can't assign anything to it. I'm not really sure what you're trying to do but something like this should work: public class myClass : Object { myObjectType[] objects; public void Save() { objects = new myObjectType[3]; for(int i = 0; i { objects[i] = ....; // whatever } } } Notice also that it's unnecessary to specify that a class inherits from Object - all classes do so by default if they don't inherit from any other class.
