Assembly: mscorlib (in mscorlib.dll)
Names that begin with or contain an underscore character (_), property accessors, and operator overloading methods are examples of types that might require special treatment by some compilers.
If the current Type represents a constructed generic type, this property applies to the generic type definition from which the type was constructed. For example, if the current Type represents MyGenericType<int> (MyGenericType(Of Integer) in Visual Basic), the value of this property is determined by MyGenericType<T>.
If the current Type represents a type parameter in the definition of a generic type or generic method, this property always returns false.
