检查对象是否来自泛型类型(不考虑泛型参数类型)

public class Box<T> {
    // ...
}

public class Main {
    public static void main(String[] args) {
        Box<String> box = new Box<>();
        String str = "Hello";
        
        System.out.println(str instanceof Box);  // false
        System.out.println(box instanceof Box);  // true
    }
}

public class Box<T> {
    // ...
}

public class Program {
    static void Main(string[] args) {
        Box<string> box = new Box<string>();
        string str = "Hello";
        
        Console.WriteLine(str is Box);  // false
        Console.WriteLine(box is Box);  // true
    }
}
