C＃でオブジェクトからオブジェクトへ変数を渡すには

public class FallenBottomEventArgs : EventArgs
{
    public int FallenX;
    public FallingRect FallingRect;
}

public delegate void FallenBottomEventHandler(object sender, FallenBottomEventArgs e);

public event FallenBottomEventHandler FallenBottom;

protected virtual void OnFallenBottom(FallenBottomEventArgs e)
{
    if (FallenBottom != null)
    {
        FallenBottom(this, e);
    }
}

FallenBottomEventArgs e = new FallenBottomEventArgs();
e.FallenX = fallingRect.X;
e.FallingRect = fallingRect;

OnFallenBottom(e);
