EventAttributes Enumeration
.NET Framework 2.0
Specifies the attributes of an event.
Assembly: mscorlib (in mscorlib.dll)
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 | |
|---|---|---|
![]() | None | Specifies that the event has no attributes. |
![]() | ReservedMask | Specifies a reserved flag for common language runtime use only. |
![]() | RTSpecialName | Specifies that the common language runtime should check name encoding. |
![]() | SpecialName | Specifies that the event is special in a way described by the name. |
