EventDescriptor Struct

Definition

Contains the metadata that defines an event.

public value class EventDescriptor
public struct EventDescriptor
type EventDescriptor = struct
Public Structure EventDescriptor
Inheritance
EventDescriptor

Remarks

This class represents an event defined in the manifest. After writing your manifest, you use the Message Compiler (MC.exe) to generate a resource file. A byproduct of the process is a header file that contains the event descriptor in C, as shown in the following example.

EXTERN_C __declspec(selectany) const EVENT_DESCRIPTOR ReadEvent = {0x1, 0x0, 0x10, 0x4, 0x0, 0x0, 0x8000000000000005};  

Use the values of the descriptor to create an instance of this class, as shown in the following example. The keyword is an unsigned long value and cannot be cast directly to a long; you must use the unchecked language keyword to allow the assignment.

unchecked  
{  
    readEvent = new EventDescriptor(0x1, 0x0, 0x10, 0x4, 0x0, 0x0, (long)0x8000000000000005);  
}  

You use the descriptor when calling the EventProvider.WriteEvent or EventProvider.WriteEvent method.
