如何判断两个对象的类型是否兼容? [英] How do I determine whether the types of two objects are compatible?

问题描述

我有一个通用函数，我想知道如何编写.

I have a generic function that I want to know how to write.

List<Something> something;

public int countItems<T>(List<T> Items)
{
    // Here I would like to compare the type of "Items" with the type of "something" to see if they are compatible. How do I do it?
    return 0;
}

推荐答案

你的意思是:

if(typeof(T) == typeof(Something)) {...}

?

请注意，拥有泛型在很大程度上取决于 T(并且行为不同)可能意味着您尝试做的实际上并不是非常泛型...

Note that having generics depend hugely on the T (and act differently) may mean what you are trying to do isn't actually very generic...
