    Search Array for value.

    Im trying to search an array for a value and I found this on StackOverflow nut wont work in NT can anyone tell me why and if there is a way of doing this,


    In .NET 3.5 or higher, using LINQ:

    bool found = yourArray.Contains(yourValue);

    Hello GKonheiser

    Thank you for the question,

    You could try using the Array.Find method to search the array for a value and depending on the result you can use an if statement to make a true or false statement for a bool value.

    Here is a example that will run in NinjaScript

    Code:
    string[] names = {"Ninja", "Trader", "Strategy"};
    string result = Array.Find(names, element => element.StartsWith("Strategy", StringComparison.Ordinal));
    if(result != null)
    {
       Print("Found");
    } else {
       Print("Not Found");
    }
    Another way you could write this to directly convert the results to a bool would be using a ternary operator. Here is another example

    Code:
    bool foundOrNotFound = false;
    string[] names = {"Ninja", "Trader", "7"};
    string result = Array.Find(names, element => element.StartsWith("7", StringComparison.Ordinal));
    foundOrNotFound = (result != null) ? true : false;
    Print(foundOrNotFound);
    Here is more information regarding the Array.Find method with some examples.

    Please let me know if I may be of additional assistance.

      Thanks Jesse,

      I ended up doing this,

      Array.IndexOf(pivots, lev[i+1]) > -1

      haven't compiled yet thou so hope it works
