_TypeThis property returns true for Type instances representing Enum and ValueType.
The ClassSemanticsMask distinguishes a type declaration as class, interface, or value type.
If the current Type represents a constructed generic type, this property returns true if the generic type definition is a class definition; that is, it does not define an interface or a value type.
If the current Type represents a type parameter in the definition of a generic type or generic method, this property always returns false.
This property is read-only.
The following example creates an instance of a type and indicates whether the type is a class.
