The keyword null represents a null literal. A null value indicates that a reference points to no object.
Examples:
object o1 = null;
if (o1 == null) Console.WriteLine("Yup, it's null");
string s1 = null; // Strings can also be null
int n1 = s1.Length; // Throws NullReferenceException, since s1 doesn't point to anything
