EventAttributes Enumeration
Specifies the attributes of an event.
This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.
Assembly: 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. |
EventAttributes values may be combined using the bitwise OR operation to get the appropriate combination.
These enums are defined in the corhdr.h file and are a combination of bits and enumerators.
The following example uses reflection emit to create a type with two events. It uses EventAttributes.None to specify that the events have no attributes.
