c# - What's the difference between encapsulating a private member as a property and defining a property without a private member?

Question

What's the difference (Performance, memory...etc) between encapsulating a private member like this

private int age;
public int Age
{
  get { return age; }
  set { age = value; }
}

and define a property like this

public int Age
{
  get ;
  set ;
}

Answer 1

In the second case, the C# compiler will generate a field for you and generate a getter and setter to access it. In other words, there is no functional difference between the two code samples you posted. The only difference will be the name of the private field, which will be compiler-generated.
