自动属性被用于在没有额外的逻辑，需要在属性访问器。
声明看起来是这样的：

Automatic Properties are used when no additional logic is required in the property accessors.
The declaration would look something like this:

public int SomeProperty {get; set;}

他们只是语法糖，所以你不会需要编写以下更加漫长code：

They are just syntactic sugar so you won't need to write the following more lengthy code:

 private int _someField;
 public int SomeProperty 
 {
    get { return _someField;}
    set { _someField = value;}
 }
