Array failed to know if it contains a string

Question

I must doing something wrong... But I can't figure it out!

I have an array with string in it. I'm trying to fins if the Array contains some words like Sales for example.

drillDownUniqueNameArray[0] = "[Sales Territory].[Sales Territories].[Sales Territory Group].&[North America]";//Inside the string array there is this string in index 0

drillDownUniqueNameArray.Contains("S")//Output false!

Array.IndexOf(drillDownUniqueNameArray,"S")//Output -1!  <--Fixed My answer

drillDownUniqueNameArray.Contains("[Sales Territory].[Sales Territories].[Sales Territory Group].&[North America]") //Output true!

I thouhgt Contains should find even part of the string..

How can I find if this array have "S" or "Sales" for example?

You are asking if the array contains a string that exactly matches "S".

What you want is to ask if any of the strings in the array contains the character "S", something like:

drillDownUniqueNameArray.Any(v => v.Contains("S"))

You're checking if the array contains an element that's exactly "S" but I think you are trying to check whether the array contains an alement that contains an "S".

You could achieve this by the following statement:

drillDownUniqueNameArray.Any( str => str.Contains ("S") )

+1 but explain reason too, if he was doing that way I suppose he didn't understand it.

You can try this. drillDownUniqueNameArray[0].Contains("s");

You can use LINQ:

var allWithSales = drillDownUniqueNameArray
    .Where(str => str.Contains("Sales"));

ignoring the case:

var allWithSalesIgnoreCase = drillDownUniqueNameArray
     .Where(str => str.IndexOf("sales", StringComparison.OrdinalIgnoreCase) >= 0);

If you want to find all that contain a word "Sales"(String.Split() = white-space delimiter)):

var allWordsWithSales = drillDownUniqueNameArray
    .Where(str => str.Split().Contains("Sales", StringComparer.OrdinalIgnoreCase));

Now you can enumerate the query with foreach or use ToArray() or ToList to create a collection:

foreach(string str in allWithSales)
    Console.WriteLine(str);

You are finding it in the array, but you should find the word in the string.

Use following if you want to check:

drillDownUniqueNameArray.Any(x=>x.Contains("Sales"));

Use following if want to get the strings which contains "Sales"

drillDownUniqueNameArray.Where(x=>x.Contains("Sales"));

When you do it like this:

drillDownUniqueNameArray.Contains("S")

it's not gonna check the values, you must do it like this:

drillDownUniqueNameArray[0].Contains("S") or drillDownUniqueNameArray.First().Contains("S")

like this way it checks the values inside the array not the arrays itself
