Hi All,

I am new to designing patterns. I would like to implement Singleton design pattern in my c#.net application.

I have few classes in my application say
Class1, Class2 and Class3

In some pages i call any one of this class, in other i may call all the three classes.

How do i implement singleton pattern in my application.

It would be great if you can provide few samples .

Thanks in advance.

Why do you want to use a Singleton pattern? A Singleton is just some kind of "global" object - sometimes that's ok, but there ought to be some reason for doing so.

You can create a manager class to get instances of these classes. You just once create objects and when you need this class you do not create objects and get these instances from manager class. Another solution which I do not choose or appreciate is create a static public instances in a class and just use these without any call.

This is a good example for first solution:
