在C#中使用泛型时的装箱

public class GenericClass<T>
{
    private T _value;

    public GenericClass(T value)
    {
        _value = value;
    }

    public T GetValue()
    {
        return _value;
    }
}

public class Program
{
    public static void Main()
    {
        GenericClass<int> intClass = new GenericClass<int>(10);
        int value = intClass.GetValue();
        Console.WriteLine(value);

        GenericClass<string> stringClass = new GenericClass<string>("Hello, World!");
        string text = stringClass.GetValue();
        Console.WriteLine(text);
    }
}
