需要有关泛型,接口和基类的帮助

public void Print<T>(T item) where T : class
{
    Console.WriteLine(item.ToString());
}

interface IMyInterface
{
    void MyMethod();
    int MyProperty { get; set; }
}

public class MyBaseClass
{
    public int MyProperty { get; set; }

    protected void MyMethod()
    {
        Console.WriteLine("MyMethod in MyBaseClass");
    }
}

public class MyDerivedClass : MyBaseClass
{
    private string _name;

    public MyDerivedClass(string name)
    {
        _name = name;
    }

    protected override void MyMethod()
    {
        Console.WriteLine($"MyMethod in {GetType().Name}: {_name}");
    }
}
