initialize DataSeries(this) into KeyValue pair (i.e. dictionary)

[ttodua]

question 1:

in Initialize I had direct BoolSeries:

my = new BoolSeries(this);

(p.s. please, dont tell me to use this as a solution! I dont need that.)

however, i wanted to change it to Dictionary. However, when I use this :

initialize()          {   my = new Dictionary<string, BoolSeries>();  }
OnBarUpdate() {   my["is_ma_crossover"][0] = ......                   }

I get error right away after adding on chart : "The given key was not present in the dictionary."
when i try without "series", then everything works well:

initialize()          {   my = new Dictionary<string, bool>();  }
OnBarUpdate() {   my["is_ma_crossover"] = ......                   }

however, i dont want that. I need to use BoolSeries in Dictionary, which i can refer with index, like:

 if(my["is_ma_crossover"][3])  {.....}

question 2
I know than NT7 uses net 3.5 version. however, which C# (maybe it is called compiler) version it used? 2.0 or 4.0 or 6.0 or which one?

Hello TazoTodua,

This would fall under general C# and is not specific to NinjaScript.

When adding an item to a Dictionary you would need to use the .Add() method.

Below is a publicly available link to the Microsoft C# documentation on Dictionary.

As well as a publicly available link to an educational site.

You would also want to call Update() in the get for the public variable.if you are not already doing this.

thanks.
1) so, i have to initialize like this?:
my.Add("is_ma_crossover", BoolSeries(this) );

(because i cant understand how to pass "this" ...


2) please, i had question 2 too, could you answer that too?

Hello TazoTodua,

It was my understanding you did not want to use a BoolSeries and instead wanted to use a Dictionary object. Is this not the case?

If you want to use a Dictionary you would not have that line of code. Instead you would declare a Dictionary and initialize this in Initialized().

private Dictionary<string, bool> myDictionary;

myDictionary = new Dictionary<string, bool>;

myDictionary.Add("element1Key", false);

Below is a link to an educational site that includes an example of how to use a Dictionary.
