 The preceding tutorials demonstrated built-in types and types you define as tuples or records. You can check instances of these types against a *pattern*. Whether an instance matches a pattern determines the actions your program takes. In the examples below, you see `?` after type names. This symbol allows the value of this type to be null (for example, `bool?` can be `true`, `false`, or `null`). For more information, see [Nullable value types](../../language-reference/builtin-types/nullable-value-types.md).  Let's start to explore how you can use patterns.
