Creating a sequence...

[new_to_code]

Hi,

I am trying to create a sequence so that every time the user clicks the submit button gets a unique 6 digit number... would this be a good start?

public static class CustomSequenceOperators
{
    public static IEnumerable Combine(this IEnumerable first, IEnumerable second, Func func) {
.......

Edit: Fixed [code][/code] tags. - Hack
