How to initialize integer array in C# [duplicate]

Answer 1

Reading up Enumerable.Repeat is 20 times slower than the ops standard for loop and the only thing I found which might improve its speed is

private static int[] GetDefaultSeriesArray(int size, int value)
{
    int[] result = new int[size];
    for (int i = 0; i < size; ++i)
    {
        result[i] = value;
    }
    return result;
}

NOTE the i++ is changed to ++i. i++ copies i, increments i, and returns the original value. ++i just returns the incremented value
