MethodAttributes Enumeration

.NET Framework 2.0

Other Versions

Specifies flags for method attributes. These flags are defined in the corhdr.h file.

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

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

Copy

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

JScript

Copy

SerializableAttribute 
FlagsAttribute 
ComVisibleAttribute(true) 
public enum MethodAttributes

Members

	Member name	Description
	Abstract	Indicates that the class does not provide an implementation of this method.
	Assembly	Indicates that the method is accessible to any class of this assembly.
	CheckAccessOnOverride	Indicates that the method can only be overridden when it is also accessible.
	FamANDAssem	Indicates that the method is accessible to members of this type and its derived types that are in this assembly only.
	Family	Indicates that the method is accessible only to members of this class and its derived classes.
	FamORAssem	Indicates that the method is accessible to derived classes anywhere, as well as to any class in the assembly.
	Final	Indicates that the method cannot be overridden.
	HasSecurity	Indicates that the method has security associated with it. Reserved flag for runtime use only.
	HideBySig	Indicates that the method hides by name and signature; otherwise, by name only.
	MemberAccessMask	Retrieves accessibility information.
	NewSlot	Indicates that the method always gets a new slot in the vtable.
	PinvokeImpl	Indicates that the method implementation is forwarded through PInvoke (Platform Invocation Services).
	Private	Indicates that the method is accessible only to the current class.
	PrivateScope	Indicates that the member cannot be referenced.
	Public	Indicates that the method is accessible to any object for which this object is in scope.
	RequireSecObject	Indicates that the method calls another method containing security code. Reserved flag for runtime use only.
	ReservedMask	Indicates a reserved flag for runtime use only.
	ReuseSlot	Indicates that the method will reuse an existing slot in the vtable. This is the default behavior.
	RTSpecialName	Indicates that the common language runtime checks the name encoding.
	SpecialName	Indicates that the method is special. The name describes how this method is special.
	Static	Indicates that the method is defined on the type; otherwise, it is defined per instance.
	UnmanagedExport	Indicates that the managed method is exported by thunk to unmanaged code.
	Virtual	Indicates that the method is virtual.
	VtableLayoutMask	Retrieves vtable attributes.

Example

The following example displays the attributes of the specified method.
