问题描述

以下是我发现用于在C#中创建getter和setter的方法。

我的问题是如何从实例访问getter和setter方法。

Following is the way I found that is used to create getter and setter in C#.
My question is how can I access getter and setter methods from instance.

class A
{
    public int id { get; set; }
};



我试过以下但是id不起作用。


I have tried following but id does not work.

A a = new A();
a.getid();

推荐答案

A a = new A();
int id = a.id;
a.id = 666;

您所说的语法称为自动实现自动属性,它只是一个简短形式:

The syntax you are talking of is called an autoimplemented or automatic property, and it's just a short form for:

private int _id;
public int id { get { return _id; } set { _id = value; }}

编译器生成 _id 支持字段。



BTW:标准是使用和初始大写字母foe属性,所以你的代码应该是:

The compiler generates the _id backing field.

BTW: The standrad is to use and initial uppercase letter foe properties, so your code should really be:

class A
{
    public int Id { get; set; }
}
...
    A a = new A();
    int id = a.Id;
    a.Id = 666;
...
