What does this mean ? public Name {get; set;} [duplicate]

Answer 1

It's called an Auto-Implemented Property and is new to C# 3.0. It's a cleaner syntax when your access to the property doesn't need any special behavior or validation. It's similar in function to:

public class Car
{
  private string _name;
  public string Name
  {
    get { return _name; }
    set {_name = value; }
  }
}

So it saves a fair amount of code, but leaves you the option later to modify the accessor logic if behavior or rules need to change.
