c#中的自动实现属性和手动属性之间有什么区别?

例如:
手册属性:

Hi Guys!!!

whats difference between Auto-Implemented Properties and manual properties in c#?

for Example:
Manual Properties:

private int uno;

        public int Uno
        {
            get { return uno; }
            set { uno = value; }
        }

自动实施的道具:

Auto Implemented Prop:

public string UserLeaveCount { get; set; }

推荐答案

不多.自动实现的属性只是编译器的语法简写.如果您使用ILSpy之类的工具查看程序集，则会看到自动实现的属性实际上在编译时便转换为property + backing字段.

现实中唯一的区别是，手动属性可以在赋值或返回值之前使用该值执行操作. auto属性只是设置或返回值.

Not much. Auto implemented properties are simply syntactic shorthand for the compiler. If you look at the assembly using a tool like ILSpy, you''ll see that an auto implemented property actually gets converted to property + backing field at compile time.

The only real-world difference is that a manual property can do things with the value before it is assigned or returned. An auto property just sets or returns the value.
