Playing with classes

I was playing little bit with classes. Idea is to see how it will behave if we declare method with type as current class instance to which this method belong.

So, I have declared class like:

public class MyClass
{
	public string mOne = "none";
	public string mTwo = "none";
	public string mAll = "none";

	public MyClass MyMethodOne()
	{
		this.mOne = "I am from method one";
		this.mAll = "My name is all and I am also from method one";
		return this;
	}

	public MyClass MyMethodTwo()
	{
		this.mTwo = "I am from method two";
		this.mAll = "My name is all and I am also from method two";

		return this;
	}

	public MyClass MyMethodNewInstanceOne()
	{
		MyClass something = new MyClass();

		something.mOne = "I am from method one";
		something.mAll = "My name is all and I am also from method one";
		return this;
	}

	public MyClass MyMethodNewInstanceTwo()
	{
		MyClass something = new MyClass();

		something.mTwo = "I am from method two";
		something.mAll = "My name is all and I am also from method two";

		return something;
	}

}

Notice for example:

this.mTwo = "I am from method two";
return this;

Here we are not creating new instance, so if we do call like:

MyClass myClassesResult = playingWithClasses.MyMethodOne().MyMethodTwo();

We will not loose any changes

That means that if we create console application like:

MyClass playingWithClasses = new MyClass();
MyClass myClassesResult = playingWithClasses.MyMethodOne().MyMethodTwo();
Console.WriteLine("************* without new instance *************");

Console.WriteLine("One: " + myClassesResult.mOne);
Console.WriteLine("Two: " + myClassesResult.mTwo);
Console.WriteLine("All: " + myClassesResult.mAll);

Result will be like:

************* without new instance *************
One: I am from method one
Two: I am from method two
All: My name is all and I am also from method two

Then notice for example:

MyClass something = new MyClass();
something.mTwo = "I am from method two";
return something;

That means that if we create console application like:

MyClass playingWithClasses = new MyClass();
MyClass myClassesNewInstanceResult = playingWithClasses.MyMethodNewInstanceOne().MyMethodNewInstanceTwo();

Console.WriteLine("************* with new instance *************");

Console.WriteLine("One: " + myClassesNewInstanceResult.mOne);
Console.WriteLine("Two: " + myClassesNewInstanceResult.mTwo);
Console.WriteLine("All: " + myClassesNewInstanceResult.mAll);

Result will be like:

************* with new instance *************
One: none
Two: I am from method two
All: My name is all and I am also from method two
