Line 7:
This can't be used normally for value types (<code>int</code>, <code>double</code>, <code>DateTime</code>, etc.) since they are no ''references,'' so the following is a compiler error:
<lang csharp>int i = null;</
With .NET 2.0 there is an additional <code>Nullable<T></code> structure which enables those semantics for value types as well:
<lang csharp>int? answer = null;
