c# - How do I order the digits 1-10 randomly into an array and then call each part of the array one at a time? -

so basically, need have numbers 1-10 randomly ordered upon startup array, , on when form loads, should load first number. each time user clicks button, load info associated next number. code, reason generates number not integer lot.

random rng = new random(10); int[] questionorder = new int[10];  (int = 0; < questionorder.length; i++) {     int temp = rng.next(1,10);     while(!(questionorder.contains(temp)))     {         questionorder[i] = temp;     } } 

each time generates number 1 - 10 , checks if has been stored in array, if not, stores , runs again.

for reason, generating numbers not integers 1 - 10, , cant figure out why.

this work nicely

    static void main(string[] args)     {         random random = new random();          var range = enumerable.range(1, 10).tolist();         int[] rnd = new int[10];          int j = 0;                 {             int = random.next(0, range.count);             rnd[j++] = range[i];             range.removeat(i);         }         while(range.count > 1);          rnd[j] = range[0];     } 

less cpu intensive using contains in loop
