What will actually happens with references when we create an instance of the class in that same class like this:
public class Class1
{
public Class1 instatnce;
}
And how it will look references when we'll try to get access to instance.

2No different to when you create an instance in another class. The question is quite unclear - what do you want to know? – Charles Mager May 05 '15 at 09:59

You've not created the reference yet. You just declared a field of same type as enclosing type. – Sriram Sakthivel May 05 '15 at 09:59

Depends if you are trying initialize it in the constructor, why not have a go? – Sayse May 05 '15 at 09:59

@CharlesMager Wrong. You'll get StackOverflowException if field initialzer or constructor creates the instance. – Sriram Sakthivel May 05 '15 at 10:00

@SriramSakthivel Which he isn't doing in the provided sample. – aevitas May 05 '15 at 10:01

@SriramSakthivel yes, there are things to watch out for. I was more interested in prodding to work out what the question actually was. 'What happens with references' isn't very clear. – Charles Mager May 05 '15 at 10:01

@aevitas Yes, but that doesn't mean "No different to when you create an instance in another class". There is a subtle difference. – Sriram Sakthivel May 05 '15 at 10:02

@CharlesMager I agree with you. Question isn't complete and unclear too. But we can't say "No different". It depends. – Sriram Sakthivel May 05 '15 at 10:03

Its not a problem. For example:
public class Class1
{
public Class1 Instance {get; set;}
}
public class Class2
{
public void Test()
{
Class1 class1 = new Class1();
var nestedInstance = class1.Instance;
}
}
Please read about singleton pattern: https://msdn.microsoft.com/en-us/library/ff650316.aspx This let you to understand this case

A class referencing itself has nothing to do with singletons. Consider a class `Employee` which has a property `public Employee Boss{get;set;}`. You can have many employees not only one, but all have a boss which is also an employee. – Tim Schmelter May 05 '15 at 10:09

Singleton is good example of this operation. How this references works – Pawel Maga May 05 '15 at 10:10
