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++

Copy

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

Copy

/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
/** @attribute FlagsAttribute() */ 
public enum TypeAttributes

JScript

Copy

public enum TypeAttributes

Members

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

Remarks

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