What's the difference between two ways of getter and setter. which is better?

Question

There are two ways to implement the getter and setter.

A:

public Object Name {get;set;}

B:

private Object _name;
public Object Name
{
       get {return this._name;}
       set {this._name = value;}
}

When we wanner get or set the property we all use

X.Name = "Joy";
String name = X.Name

So I just want to know the difference between them.

Thank you.

Short answer: there is no difference. You use the first when you can and the second when you must. — Jon, Jun 14 '13 at 09:22

The first one is Auto-Implemented Properties which is basically syntactic sugar and results in the same as the second approach.

When using the first auto implemented properties the c# compiler will generate a backing field just like you have it declared in the second case.

If you want to make the property read only you can use declare it like this:

public Object Name {get; private set;}

They're just the same. The first one is just syntactic sugar.

But if you want to add some logic, say validate the setter value, the second one is what you need.
