Question

i have a user defined list

public class Level2
{
    public double price { get; set; }
    public int size { get; set; }

    public Level2(double price, int size)
    {
        this.price = price;
        this.size = size;
    }
}

in my program i have this snippet which i loop through the first 10 elements

List<Level2> bid = new List<Level2>();

        for (int i = 0; i < 10; i++)
        {
            if (i < bid.Count && bid[i].price > bid[0].price - (20 * process.tickSize))
            {
                bidString = bidString + "," + bid[i].price.ToString() + "," + bid[i].size.ToString();
            }                
        }

and it compile and runs fine.
Now i need to expand my program and want to change my variable to an array type, like this:

 List<Level2>[] bid = new List<Level2>[5];

how can i change my loop, so i can loop through the first array, ie bid[0] ?

please provide some working snippet, thank you very much

Answer 1

Replace all bid with bid[0]

List<Level2>[] bid = new List<Level2>[5]; 

    for (int i = 0; i < 10; i++) 
    { 
        if (i < bid[0].Count && bid[0][i].price > bid[0][0].price - (20 * process.tickSize)) 
        { 
            bidString = bidString + "," + bid[0][i].price.ToString() + "," + bid[0][i].size.ToString(); 
        }                 
    } 

Alternatively use a different variable for the bid array

List<Level2>[] bidArray = new List<Level2>[5];

then assign bid to be the first element

List<Level2> bid = bidArray[0];

and then continue with your existing code.
