通用参数.如何传入构造函数然后添加到列表？

Question

我上课了

class ExpiryList
{
    protected ConcurrentDictionary <GenericType, DateTime> m_list;

    ExpiryList(GenericType obj, DateTime expiryDate)
    {
        m_list.AddOrUpdate(obj, expiryDate, (x, y) => { return expiryDate; });
    }
}

我想知道如何实现这个？我需要一种方法来创建这个类的实例,它将int,string,String,double等存储到GenericType变量中.

你可以使你的类通用:

class ExpiryList<TAnyType>
{
    protected ConcurrentDictionary <TAnyType, DateTime> m_list;

    ExpiryList(TAnyType obj, DateTime expiryDate)
    {
        m_list.AddOrUpdate(obj, expiryDate, (x, y) => { return expiryDate; });
    }
}
