        public var time:Number;
        public var stream:ByteArray;

        public static const COMPLETE:String = "mergeComplete";

        public function MergedEvent(type:String, stream:ByteArray, duration:Number)
        {
            super(type, false, false); // base
            this.stream = stream;
            this.time = duration;
        }
    }
}

Answer 1

In C# you have two separate items, an EventHandler<TArgs> declaration and the custom EventArgs subclass.

public event EventHandler<MergedEventArgs> MergeComplete;

public class MergedEventArgs : EventArgs {
    public double Time { get; set; }
    public byte[] Stream { get; set;
}
