存放在C＃中的方法列表 [英] Storing a list of methods in C#

问题描述

我有，我想在一个特定的顺序调用方法的列表。因此，我希望将它们存储或以有序列表中或者在与指定的索引的表。这种方式名单是改变我们想改变来电订购当天唯一

I have a list of method that I would like to call in a specific order. Therefore I would want to store them either in an ordered list or in a table with a specified index. This way the list would be the only thing to change the day we want to change the call order.

我发现的这篇文章解释如何使用数组和代表去做。但我评价和其他一些地方，它也可以使用字典和或LINQ进行读取。有何意见？

I found this article explaining how to do it using an array and delegates. But I read in the comments and some other places that it could also be done using a Dictionary and or LinQ. Any advices ?

推荐答案

您可以定义动作的对象，这是参返回无效代表。每个动作指向一个方法

You can define Action objects, which are parameterless delegates that return void. Each action is a pointer to a method.

// Declare the list
List<Action> actions = new List<Action>();

// Add two delegates to the list that point to 'SomeMethod' and 'SomeMethod2'
actions.Add( ()=> SomeClass.SomeMethod(param1) );
actions.Add( ()=> OtherClass.SomeMethod2() );

// Later on, you can walk through these pointers
foreach(var action in actions)
    // And execute the method
    action.Invoke();
