New string or object reference? -- dotnet clr

dotnet clr : New string or object reference?

Hello!

See the code below:

public class Customer
{
private string name;

public Customer(string name) : base()
{
this.name = name;
}

public string Name
{
get { return this.name; }
set { // some implementation ... }
}
}

public class SomeClass
{
public void Main()
{
string name;
Customer customer = new Customer("John");

// Does it returns the string's reference or its copy?
name = customer.Name;

Console.WriteLine(name);
}
}

That's it, a very simple code. Here goes the question:
Does the <Customer.Name> property return the object reference of the
string at the <Customer.name> field, or a copy of that string?

Thank you in advance!

Jon, these explanations about memory and parameters are just what I was
looking for. Very good pages!

Thank you.

It returns a copy of the reference to the same object. It's very, very
important that you understand the difference between reference types
and value types. Have a look at
http://www.pobox.com/~skeet/csharp/parameters.html and
http://www.pobox.com/~skeet/csharp/memory.html

Hopefully they'll clarify things for you. It's one of those things that
is really simple once it's clicked, but maddening and complicated until
it has...

Ah.. looking at the thread I knew Jon would've replied... surely,
history repeats itself... and in case of reference types, it seems to be
repeating every 24 hours :) Jon to the rescue!
