Make a reference to another string in C#

Question

As far as I know a string in C# is a reference type.

So in the following code \'a\' should be equal to \"Hi\", but it still keeps its value which is \"Hello\". Why?<

Answer 1

The concept of a reference type is the most confusing thing amongst OOP programmers.

Run the below code, and you will be surprised to see the answer:

Create a simple Book class with a property called Name and write the below code in the Main method of the application.

Book a = new Book() {Name = "book a"};
Book b = new Book() {Name = "book b"};

Book c = a; //line 3

Book a = b; //Line 4

Console.WriteLine(c.Name);

And as no doubt you will expect the answer to be "book b" because of line 4. You think that as c is a and after that a became b which will also make c equals b.

Which is not the case!
