如何通过集合中的字符串值调用适当的方法? [英] How to call an appropriate method by string value from collection?

问题描述

我有一个字符串集合.例如

I have a collection of strings. For example,

string[] coll={"1", "2", "3" ..."100"..."150"...} 

并且我有相应的字符串收集方法，例如

and I have respective methods for the string collection such as

void Method1, void Method2, void Method100

我选择类似的方法:

string selector=string.Empty;
switch(selector)
 { case "1": 
            MethodOne();
            break;
    ........
    case "150":
            Method150();
            break;
  }

上面的代码真的很无聊，我在字符串集合{"150" ..."250" ...}中将有更多的字符串元素.怎么做:

The above code is really bored and I will have more string elements in the string collection {"150" ... "250"...}. How to make like that:

 string sel=col[55];
 if(sel!=null)
        // call here the respective         method(method55)

我不想使用开关运算符，因为它会导致代码过多.

I do not want to use switch operator cause it gives rise to surplus of code.

推荐答案

您可以使用键和类似的动作声明字典

You can declare a dictionary with your keys and actions like

Dictionary<string, Action> actions = new Dictionary<string, Action>()
{
    { "1", MethodOne },
    { "2", ()=>Console.WriteLine("test") },
    ............
};

并将其调用为

actions["1"]();

PS:假设方法 void MethodOne(){} 在某处声明.

PS: Presuming method void MethodOne(){ } is declared somewhere.
