Add 500 new objects to array using C#

Question

It it possible to add 500 objects by for loop into an array using C#?

    public class DataBase
    {
        public Items[] GetItems()
        {
            return new Items[] {
                new Items (1, "item1" ),
                new Items (2, "item2"),
                new Items (3, "item3")};

                // for here?
        }

    }

The items should be unique :) also first value in Items object is uint, so it should be converted somehow?

are u using a model for adding? or u just simple want to add using pattern above? — Masoud Andalibi

You can give this a try return Enumerable.Range(1, 500).Select(x => new Items (x, "item" + x )).ToArray(); — Satpal

@Satpal should it be .ToArray after => new Items (...) ? 1 more thing! "x" or first value in Items object is uint, how can I convert it to uint dynamically ? — bodley

Enumerable.Range:

public class DataBase
{
    public Items[] GetItems()
    {
        return Enumerable.Range(1,500).Select(o => new Items ((uint)o, "item" + o)).ToArray();     
    }
}

Reference:

public static IEnumerable<int> Range(
    int start,
    int count
)

You can use Enumerable.Range and type case x to unit

return Enumerable.Range(1, 500).Select(x => new Items((uint)x, "item" + x)).ToArray();
