Java8 java.util.function.Consumer<>的c#等价物是什么？
Java8 java.util.function.Consumer<>的c#等价物是什么？
提问于 2016-04-06 19:08:04
在C#中是否有与此接口等效的接口？
示例：
Consumer<Byte> consumer = new Consumer<>();
consumer.accept(data[11]);我已经在Func<>和Action<>上搜索过了，但我不知道。
Consumer.accept()接口的原始Java代码非常简单。但对我来说不是：
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); };

Consumer<T>对应于Action<T>，andThen方法是一个排序运算符。您可以将andThen定义为扩展方法，例如
public static Action<T> AndThen<T>(this Action<T> first, Action<T> next)
{
return e => { first(e); next(e); };
