隐含运算符？

Question

I need some help. 我需要一些帮助。 I am creating a SelectItem class like this: 我正在创建一个像这样的SelectItem类：

public class SelectItem<T> where T : class
{
    public bool IsChecked { get; set; }
    public T Item { get; set; }
}

I would like the following code to be valid 我希望以下代码有效

SelectItem<String> obj = new SelectItem<String> { Item = "Value" };

obj.IsChecked = true;

String objValue = obj;

Instead of having to do this: 而不是必须这样做：

String objValue = obj.Item;

How can I accomplish this? 我怎么能做到这一点？

public static implicit operator T(SelectItem<T> obj) {
    return obj.Item;
