Check if a Nullable has a value

int? i = null;

if (i != null)
{
    Console.WriteLine("i is not null");
}
else
{
    Console.WriteLine("i is null");
}

Which is the same as:

if (i.HasValue)
{
    Console.WriteLine("i is not null");
}
else
{
    Console.WriteLine("i is null");
}

Found a mistake? Have a question or improvement idea? Let me know.
