Question

I Have a class

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

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

And i am wondering how to implement this? I need a way to create an instance of this class that stores either int, string, String, double etc… into the GenericType variable.

You can make your class generic:

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

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