String Array

Is there any method to find the number of elements that are filled in an array

lets say i have the following array defined

string[] text = new string[50]

and i fill the first 8 elements/indexes

Is there any method that could return the number of elements/indexes within an string array that are filled?

I tried using text.lenght() but that returns the total size of array. In above case it would return 50 which is not what i want...

Hello, gallian99.
I haven't heard about such standard functions I can offer two alternative ways for you:
1. Using reference types (like ArrayList). You'll able to add elements dynamically and get the actual size of your array.
2. Create your own structure/class, that will contain your array, the full array size (in your case it's 50) and number of added elements.
So what if you can see the darkest side of me?

Thanks Anteka,

I have tackled it using an alternate already. But I should better try ArrayList as well. Haven't work around with it yet

If you are running on .NET 3, you can use Lists, which are very easy:

C# Syntax (Toggle Plain Text) 
  1. List<String> strings = new List<String>(); //initialise the list
  2. strings.Add(str); //Add an item
  3. int length = strings.Count; //how many strings are in the list.

You should follow scru's advice and use a List<T> if you want to have a resizable container.

An ArrayList is also resizable, still usable but a bit "out of date".
If I where you follow the advise off scru and Rashakil Fol.
