在C#是什么代码"获得"意思?
问题描述:
我是新的C#
private string m;
public string M { get { return m; } }
这是一种在C#中的getter / setter像Java的?
Is this kind of a getter/setter in C# like Java?
答
这部分是一个领域:
private string m;
这部分是返回的 m的值一个只读属性
字段:
public string M { get { return m; } }
您能做出这样一个读写属性,像这样:
You could make this a read-write property like so:
public string M {
get { return m; }
set { m = value; }
}
或者你可以在那里有更复杂的逻辑:
Or you could have more complex logic in there:
public string M {
get {
if (string.IsNullOrEmpty(m))
return "m is null or empty";
return m;
}
}
基本上,字段只拿着东西的好,而性能更喜欢的方法和可能引入逻辑。
Basically, fields are only good at holding things, while properties are more like methods and can introduce logic.
