Question

C＃是否有一些模式/语法/库来完成类似Ruby on Rails（https://apidock.com/rails/Module/delegate）上的委托助手方法的工作？

问题是，如果您用Google搜索C＃的委托人，您只会找到有关C＃委托人概念的信息，该信息与rails中的概念稍有不同。

继续旅行，Javascript / Typescript是否也有等效功能？

Answer 1

c＃中没有等效项，您需要在每种情况下手动实现它（创建Facade方法）。

链接示例：

class Foo
  CONSTANT_ARRAY = [0,1,2,3]
  @@class_array  = [4,5,6,7]

  def initialize
    @instance_array = [8,9,10,11]
  end
  delegate :sum, to: :CONSTANT_ARRAY
  delegate :min, to: :@@class_array
  delegate :max, to: :@instance_array
end

Foo.new.sum # => 6
Foo.new.min # => 4
Foo.new.max # => 11

可以翻译为c＃：

public class Foo
{
    public static readonly IReadOnlyList<int> CONSTANT_ARRAY = new[] {0, 1, 2, 3};
    public static int[] class_array = {4, 5, 6, 7};

    public int[] instance_array = {8, 9, 10, 11};

    public int sum() => CONSTANT_ARRAY.Sum();
    public int min() => class_array.Min();
    public int max() => this.instance_array.Max();
}
...
new Foo().sum(); // => 6
new Foo().min(); // => 4
new Foo().max(); // => 11

C＃
