传入类型以进行检查 [英] Pass in Type to check against

问题描述

我有一个方法，我在其中检查循环中的当前对象是否与我传递给方法的类型相同.

I have a method in which I'm doing a check to see if the current object in a loop is the same type as a type I pass into the method.

起初我将类型作为字符串传递给方法，然后使用:

At first I was passing the type into the method as a string and then using:

item.GetType().ToString().Equals(myType);

我真正想做的是使用 is 关键字来做:

What I'd really prefer to do is use the is keyword to do:

item is myType

我遇到的问题是将 myType 传递给方法.我需要使用某种时髦的泛型类型吗?我将类型的引用传递为什么类型?

The problem I'm having is passing in myType to the method. Do I need to use some kind of funky generics type or something? What type do I pass in a reference ot a type as?

推荐答案

是这样的吗?

public static bool ContainsType<T>()
{
    object[] objects = new object[] { };

    foreach (var o in objects)
    {
        if (o is T)
        {
            return true;
        }
    }

    return false;
}

public static void Main(string[] args)
{
    ContainsType<int>();
}
