The following example shows how to use the EventSource.EventData structure.

        
        [NonEvent]
        public unsafe void WriteEvent(int eventId, int arg1, int arg2, int arg3, int arg4) {
            EventData* dataDesc = stackalloc EventProvider.EventData[4];

            dataDesc[0].DataPointer = (IntPtr)(&arg1);
            dataDesc[0].Size = 4;
            dataDesc[1].DataPointer = (IntPtr)(&arg2);
            dataDesc[1].Size = 4;
            dataDesc[2].DataPointer = (IntPtr)(&arg3);
            dataDesc[2].Size = 4;
            dataDesc[3].DataPointer = (IntPtr)(&arg4);
            dataDesc[3].Size = 4;

            WriteEventCore(eventId, 4, (IntPtr)dataDesc);
        }
