TypeAttributes Enumeration

.NET Framework 4.5

Other Versions

Specifies type attributes.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Namespace: System.Reflection
Assembly: mscorlib (in mscorlib.dll)

Syntax

C++

[SerializableAttribute]
[ComVisibleAttribute(true)]
[FlagsAttribute]
public enum TypeAttributes

Members

	Member name	Description
	VisibilityMask	Specifies type visibility information.
	NotPublic	Specifies that the class is not public.
	Public	Specifies that the class is public.
	NestedPublic	Specifies that the class is nested with public visibility.
	NestedPrivate	Specifies that the class is nested with private visibility.
	NestedFamily	Specifies that the class is nested with family visibility, and is thus accessible only by methods within its own type and any derived types.
	NestedAssembly	Specifies that the class is nested with assembly visibility, and is thus accessible only by methods within its assembly.
	NestedFamANDAssem	Specifies that the class is nested with assembly and family visibility, and is thus accessible only by methods lying in the intersection of its family and assembly.
	NestedFamORAssem	Specifies that the class is nested with family or assembly visibility, and is thus accessible only by methods lying in the union of its family and assembly.
	LayoutMask	Specifies class layout information.
	AutoLayout	Specifies that class fields are automatically laid out by the common language runtime.
	SequentialLayout	Specifies that class fields are laid out sequentially, in the order that the fields were emitted to the metadata.
	ExplicitLayout	Specifies that class fields are laid out at the specified offsets.
	ClassSemanticsMask	Specifies class semantics information; the current class is contextful (else agile).
	Class	Specifies that the type is a class.
	Interface	Specifies that the type is an interface.
	Abstract	Specifies that the type is abstract.
	Sealed	Specifies that the class is concrete and cannot be extended.
	SpecialName	Specifies that the class is special in a way denoted by the name.
	Import	Specifies that the class or interface is imported from another module.
	Serializable	Specifies that the class can be serialized.
	WindowsRuntime	Specifies a Windows Runtime type.
	StringFormatMask	Used to retrieve string information for native interoperability.
	AnsiClass	LPTSTR is interpreted as ANSI.
	UnicodeClass	LPTSTR is interpreted as UNICODE.
	AutoClass	LPTSTR is interpreted automatically.
	CustomFormatClass	LPSTR is interpreted by some implementation-specific means, which includes the possibility of throwing a NotSupportedException. Not used in the Microsoft implementation of the .NET Framework.
	CustomFormatMask	Used to retrieve non-standard encoding information for native interop. The meaning of the values of these 2 bits is unspecified. Not used in the Microsoft implementation of the .NET Framework.
	BeforeFieldInit	Specifies that calling static methods of the type does not force the system to initialize the type.
	ReservedMask	Attributes reserved for runtime use.
	RTSpecialName	Runtime should check name encoding.
	HasSecurity	Type has security associate with it.

Remarks

The members of this enumerator class match the CorTypeAttr enumerator as defined in the corhdr.h file.
