We Can Achieve Singleton Design Pattern By restricting Other
Class To Make Object of the class By Using Constructor
instead we can Use A Static Method to get hold of the
Instance of the class , And By making our Constructor
private we can Restrict other classes to make Instance of
the Class , So that All other Classes use the same static
method to make only one instance of the class.

Singleton design pattern can be achieved by following implementation:
1) Make class public
2) Static method to generate the instance of class(calling this method we can get the instance of a class if already a instance is generated we will get the same instance)
3) Private Constructor (so that no other class can generate the instance of singleton class)
Example::
class Class1
{
private static Class1 classInstance;
private IList<int> list = new List<int>();
private Class1()
{
if (list == null)
{
list = new List<int>();
}
}
public static void GetInstance()
{
if (classInstance == null)
{
classInstance = new Class1();
}
}
}
