Search Array for value.

[GKonheiser]

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

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

bool foundOrNotFound = false;
string[] names = {"Ninja", "Trader", "7"};
string result = Array.Find(names, element => element.StartsWith("7", StringComparison.Ordinal));
[B]foundOrNotFound = (result != null) ? true : false;[/B]
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
