我有2个班:

public class Articles
{
    private string name;

    public Articles(string name)
    {
        this.name = name;
    }

    public void Output()
    {
        Console.WriteLine("The class is: " + this.GetType());
        Console.WriteLine("The name is: " + name);
    }
}

和

public class Questionnaire 
{
    private string name;

    public Questionnaire(string name)
    {
        this.name = name;
    }

    public void Output()
    {
        Console.WriteLine("The class is: " + this.GetType());
        Console.WriteLine("The name is: " + name);
    }
}

我想写一个方法,它取一个整数(1表示Articles应该返回,2表示意思Questionnaire)和一个名字.

此方法必须返回这两个类之一的实例:
