String Array

Expand Post »

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...

Re: String Array

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.

Re: String Array

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

Re: String Array

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

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

Re: String Array

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

Re: String Array

An ArrayList is also resizable, still usable but a bit "out of date".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.

Well this is about the dumbest reply I've read on this forum. Did you even read the question?
