C# output different from breakpoint output [duplicate]

Answer 1

You should create the Random before the loop.

public static void LoadCards()
{
    Deck deck = new Deck();
    Random r = new Random();
    for (int i = 0; i < 24; i++)
    {
        YourDeck.Add(deck.CardNames[r.Next(0, 14)]);
    }
}

The default constructor of Random

Initializes a new instance of the Random class, using a time-dependent default seed value.

The default seed value is derived from the system clock and has finite resolution. As a result, different Random objects that are created in close succession by a call to the default constructor will have identical default seed values and, therefore, will produce identical sets of random numbers.
