将运算符存储在变量中

本文介绍了将运算符存储在变量中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

是否可以将运算符存储在变量中?我想做这样的事情(伪代码):

Is there a way to store an operator inside a variable? I want to do something like this (pseudo code):

void MyLoop(int start, int finish, operator op)
{
    for(var i = start; i < finish; op)
    {
        //do stuff with i
    }
}

然后我可以像这样调用此方法:

I could then call this method like so:

MyLoop(15, 45, ++);
MyLoop(60, 10, --);

C#中是否存在类似的东西?

Does something like this exist in C#?

我想是这样的.您无需定义运算符，而可以定义一个函数(lambda)来为您完成更改.

I suppose something like this. You do not define the operator, but a function (lambda) which does the change for you.

void MyLoop(int start, int finish, Func<int, int> op)
{
    for(var i = start; i < finish; i = op(i))
    {
        //do stuff with i
    }
}

然后我可以像这样调用此方法:

I could then call this method like so:

MyLoop(15, 45, x => x+1);
MyLoop(60, 10, x => x-1);
