C#——对象初始值设定项

使用对象初始值设定项:

*在创建对象时，向对象的任何可访问字段或属性分配值

*可为构造函数指定参数或忽略参数

public class Cat
{
    // Auto-implemented properties.
    public int Age { get; set; }
    public string? Name { get; set; }

    public Cat()
    {
    }

    public Cat(string name)
    {
        this.Name = name;
    }
}

Cat cat = new Cat { Age = 10, Name = "Fluffy" };
Cat sameCat = new Cat("Fluffy"){ Age = 10 };
