从对象初始化访问属性 [英] Accessing properties from object initializer

问题描述

我有如下的人类

class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string FullName
    {
        get { return FirstName + " " + LastName; }
    }
    public IEnumerable<Person> Children { get; set; }
}

我可以初始化它是这样的：

I could initialize it like this:

Person p = new Person() { FirstName = "John", LastName = "Doe" };

但有可能引用人的另一个属性的对象初始化，所以我可以做的，例如这样的事情？

But is it possible to reference another property of Person in the object initializer, so I could do for example something like this?

Person p = new Person()
{
    FirstName = "John",
    LastName  = "Doe",
    Children  = GetChildrenByFullName(FullName);
};

修改

为了这个问题，所引用的属性没有根据其他属性来计算，但它的价值可能在构造函数中进行设置。

For the sake of the question, the referenced property doesn't have to be calculated according to other properties, but its value could be set in the constructor.

感谢

推荐答案

可以这样做：

void Foo()
{ 
  String FullName = "";

  Person p = new Person()
  {
    FirstName = "John",
    LastName  = "Doe",
    Children  = GetChildrenByFullName(FullName); // is this p.FullName 
                                                 // or local variable FullName?
  };
}
