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