C# typeof operator and GetType()

C# typeof operator is used to check the type of a data type or its alias passed as argument at compile time. The typeof() operator can take bounded or unbounded type as its parameter. The term unbound type refers to a nongeneric type or an unbound generic type.

The types of the C# language are divided into two main categories: value types and reference types. Both value types and reference types may be generic types, which take one or more type parameters. Type parameters can designate both value types and reference types. Microsoft Doc
