Sorting a two dimesional array

[Ricam]

I'm restoring my indicators from a backup after a computer wipeout.

There are (2) arrays of doubles: sortedLevels[,] and _levels[,] .

The following line of code doesn't compile anymore... it used to!

sortedLevels=_levels.OrderBy(x => x[1]);

The Ninjascript editor Intellisense dropdown DOES include the OrderBy method. The indicator does have "using" references to Linq and Collections, Generic.,

The error message is:

Double[,] does not contain a definition for OrderBy and no extension method OrderBy accepting first argument type double [,] could be found. Are you missing a directive or an assembly reference?

Can you please assist? Thank you.

Hello Ricam,

May we have a screenshot of the references window?

I would expect System.Linq to be available with the System.dll.

Try making a clean install environment, then create a new test script with only that code.

Seems to be fixed. Compiles OK now, but haven't yet checked that the sort is working.

I pasted this static public class into the MyCustomMethods Add-On, in the Indicator namespace.

But should it be necessary to do this?

Hello Ricam,

This shouldn't be necessary, it sounds like something is missing from your setup

Did you try a basic test using OrderBy in a clean environment?

If the clean environment works, do you still see issue after performing a Repair operation with a NinjaTrader installer?

Please also include a screenshot showing your references in the NinjaScript Editor.
