C# Null-Coalescing Operator

The ?? operator allows you to specify a default value when a nullable type is assigned to a non-nullable type.

Let’s define a nullable int, using the Nullable shorthand:

int? x = null;

By using the ?? operator we can assign x to y while enforcing a default value for cases where x is null. Here we set the default to zero:

int y = x ?? 0;
