Dynamic Array Size

Question

User1203305613 posted

I have the below code where I pass an array.

Filters.Add("[dbo].[Employees].[EmployeeID]", new int[5] { 1, 2, 3, 4, 5 });

How do I make it dynamic ,say onetime it should be 

Filters.Add("[dbo].[Employees].[EmployeeID]", new int[6] { 1, 2, 3, 4, 5,6 });

Next time it could be 

Filters.Add("[dbo].[Employees].[EmployeeID]", new int[4] { 1, 2, 3, 4, });

Use generics, List<int>, rather than an array.

You have a problem with the code you are calling but you don't show the code with the problem!  What does the called method look like?

void Add(string x, int[] numbers)

(Mind you, I agree with the previous answer.  Don't use arrays - they are very old fashioned)

Thanks for your suggestion 

The code Is from Product I need to pass an array ,I cannot alter their product code   . But I want to make the size of array of dynamic.

Filters.Add("[dbo].[Employees].[EmployeeID]", new int[5] { 1, 2, 3, 4, 5 });.

Its like Filter.Add("Column Name",Array);

I want to make the Array dynamic.

The method is from a Product,its a call to API which I don't have control

Make it a List, Add Items and then later convert it to Array.

List<int> lst = new List<int>();
lst.Add(1);
lst.Add(2);
lst.Add(3);
int[] arr = lst.ToArray();

Are you saying that you cannot change the Filters.Add() method?

If that method is expecting a fixed sized array then it will not work unless you pass a fixed sized array.

You still haven't shown us the signature of the method you are trying to call (filters.Add())

Hi KALYANA ALLAM,

According to your description, I suggest you could refer the following code snippets. Please pay attention to my comments in the code.

    static void Main(string[] args)
    {
        List<int> list = new List<int>();
        list.Add(1);
        list.Add(2);
        list.Add(34);
        list.Add(66);
        list.Add(343);
//Dynamic Array? is this the effect you want.
        Console.WriteLine(Sum(list.ToArray()));
        Console.ReadKey();
    }
// Functions we can't change
    protected static int Sum(int[] array)
    {
        return array.Sum(x => x);
}

Result.

Feel free to let me know if you have any question.

Best Regards,

Abraham.
