NT 8.1.2.0 code (BarLine as IDrawingTool).ZOrder = int.MaxValue; gives error

[hotsalamii]

On Version 8.0.28.0, the following code compiles without error, however, when I migrated the code over to 8.1.2.0, it gives me an error: ')' expected. The error is on the second line of the code (BarLine as IDrawingTool).ZOrder = int.MaxValue; Anyone know why this code generated this error?

NinjaTrader.NinjaScript.DrawingTools.Line BarLine = Draw.Line(this, tag, isAutoScale, startBarsAgo, startY, endBarsAgo, endY, brush, dashStyle, width);

(BarLine as IDrawingTool).ZOrder = int.MaxValue;

Hello hotsalamii,

Welcome to the NinjaTrader forums!

The error that a closing parenthesis ')' is expected may imply that the syntax in the code above this point is incorrect somewhere.

Also, it may not be necessary to cast this to IDdrawingTool to set the ZOrder as it is already a drawing tool.

BarLine.ZOrder = int.MaxValue;

I don't understand either why you would cast it to an IDrawingTool. It's already a Line which has more capabilities than an IDrawingTool so you're making it harder on yourself than necessary. Just change the line's ZOrder. There's no need to cast it at all.

I removed the typecast from the code and it compiled fine. I am still curious as to why the error message about the error: ')' expected when trying to typecast.
Thanks for the comment @NinjaTrader_ChelseaB and @QuantKey_Bruce
