How could I write a while loop that said the following (pseudo code):
While the index of "blahblah" in string 1 exists
do this
while(string1.Contains("blahblah")) {
// do this
}
Pseudocode compiled to C# successfully. 0 errors, 0 warnings. Time taken: 0:00:01.860.
var string1 = "blahblah blahblah blahblah blahblah ";
int pos = -1;
while (0 >= (pos = string1.IndexOf("blahblah", pos + 1)))
{
// do this.
}

this for loop inside arrays is working like while and printing only the second index.
what should i do to make it print only even indexes?
You have inverted the += operator in your for loop. You're saying i = +2 which is the same as i = 2
The correct code would be:
for (int i = 0; i < cars.Length; i += 2)
{
Console.WriteLine(cars[i]);
}

private int skor 0;

You are missing assignment operator = in your skor declaration:
private int skor = 0;

I am trying to check to see if this object contains any letters besides Z and if it does it should return Null. The way I have it initialized gives me no errors but when testing it does not actually return null if a letter is present.
if(request.DoorTag.Contains(#"[a - yA - Y]"))
{
return null;
}
if(Regex.IsMatch(request.DoorTag, "[a-yA-Y]")
{
return null;
}
But "[^zZ]" would even be better, since it'll check that your DoorTag contains any other char than Z

I am attempting to define a queue named movingAverages with a size of queue.Count - period. I am getting an error "int IEnumerable.Count() ... - cannot be applied to method and int....
private static IEnumerable<DateClose> MovingAverage(
IEnumerable<DateClose> queue, int period)
{
Queue<DateClose> movingAverages = new Queue<DateClose>(queue.Count + period);
return movingAverages;
}
Well it's because IEnumerable<T>.Count is a method, so you are missing the parentheses at queue.Count + period, which should be queue.Count() + period.

How can I Increment a label by 20 each time I click a button I've tried with this code:
private int sjokolade = 0; (outside of void)
sjokolade = +20;
this.metroTile1.TileCount = 1;
label1.Text = (+sjokolade).ToString();
Thanks!
You want to use += and not =+ since the first is a shorthand for sjokolade= sjokolade+20 and the second is setting it equal to positive 20.
