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 EventSource.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);  
}
