什么是Java 8 java.util.function.Consumer <>的c#等价物？

Question

在C#中是否有相当于这个接口？

例:

Consumer<Byte> consumer = new Consumer<>();
consumer.accept(data[11]);

我四处搜寻Func<>,Action<>但我不知道.

Consumer.accept()接口的原始Java代码非常简单.但不适合我:

void accept(T t);

/**
* Returns a composed {@code Consumer} that performs, in sequence, this
* operation followed by the {@code after} operation. If performing either
* operation throws an exception, it is relayed to the caller of the
* composed operation.  If performing this operation throws an exception,
* the {@code after} operation will not be performed.
*
* @param after the operation to perform after this operation
* @return a composed {@code Consumer} that performs in sequence this
* operation followed by the {@code after} operation
* @throws NullPointerException if {@code after} is null
*/
default Consumer<T> andThen(Consumer<? super T> after) {
    Objects.requireNonNull(after);
    return (T t) -> { accept(t); after.accept(t); };
}

Answer 1

"Consumer接口表示接受单个输入参数并且不返回任何结果的操作"

好吧,如果这个引用来自这里是准确的,它大致相当于Action<T>C#中的委托;

例如这个java代码:

import java.util.function.Consumer;

public class Main {
  public static void main(String[] args) {
    Consumer<String> c = (x) -> System.out.println(x.toLowerCase());
    c.accept("Java2s.com");
  }
}

在C#中会是:

using System;

public class Main
{
  static void Main(string[] args)
  {
     Action<string> c = (x) => Console.WriteLine(x.ToLower());
     c.Invoke("Java2s.com"); // or simply c("Java2s.com");
  }
}
