构造链接，我做对了吗？

Question

我正在学习构造函数链接以减少冗余代码，并且只是想知道我是否有一个正确的把握并且做得对。我是否还需要第三个构造函数中的this.Name = restaurantName？这是代码：

 public Restaurant()
    {
        this.Name = DefaultName;
        this.Chain = null;
        this.SeatingCapacity = MinSeats;
        this.Smoking = false;
        this.LastMonthSales = MinSales;
        this.LastMonthCosts = MinCosts;
        this.OpenDays = new List<DayOfWeek>();
    }

    public Restaurant(string restaurantName)
        :this()
    {
        this.Name = restaurantName;            
    }

    public Restaurant(string restaurantName, int capacity)
        :this(restaurantName)
    {            
        this.SeatingCapacity = capacity;            
    }

Answer 1

您可以通过参数化主构造函数来简化这一点，然后传递其他重载的默认值：

public Restaurant(string restaurantName, int capacity)
{
    this.Name = restaurantName;
    this.Chain = null;
    this.SeatingCapacity = capacity;
    this.Smoking = false;
    this.LastMonthSales = MinSales;
    this.LastMonthCosts = MinCosts;
    this.OpenDays = new List<DayOfWeek>();
}

public Restaurant(string restaurantName) : this(restaurantName, MinSeats)
{}

public Restaurant() : this(DefaultName)
{}
