I can match the apple using pattern matching, and only enter the case when the condition is met. This is thrown when we access a property of an object reference, assuming it exists. Use the throw statement to throw an exception. Before we get started with pattern matching enhancements in c# 9, much of it is based off the improved switch syntax from c# 8. You can use pattern matching as well as the is and as operators to safely convert types. Web the associated option for this rule specifies whether to prefer pattern match or an as expression with null checks to determine if something is of a particular type. Web pattern matching can be used to check the type of an object and perform actions based on the type.
