NullableTypes Namespace

NullableTypes for .NET are a very reliable and efficient version of built-in value-types that can be Null. NullableTypes pass more than 800 differents test cases and have close-to-optimal efficiency as built-in value-types. They may be used every time you need to store a Null value in a .NET built-in value-type. NullableTypes let you write code like this:

        public sealed class Order{
            public int OrderID {get {/*...*/}}
            public int CustomerID {get {/*...*/}}
            public NullableDateTime RequestedDeliveryDate {get {/*...*/}}
            // remaining members elided for clarity
        }

where RequestedDeliveryDate can be either NullableDateTime.Null or a valid DateTime value. The property RequestedDeliveryDate.IsNull tests if the date is Null, and when it is not Null the property RequestedDeliveryDate.Value returns a valid DateTime value.
