how to generate combination of number length 2 in asp.net c#












0














I have 1-9 digit number and want to generate probability (combination) of number without duplicate and with duplicate.



int array = {1, 2, 3, 4};


I need the output to be like this:



{1,2}{1,3}{1,4}{2,1}{2,3}{2,4}{3,1}{3,2}{3,4}{1,1}{2,2}{3,3}{4,4}





combinations permutation probability

Do something like this.



for(int i = 0 ; i < array.size() ; i ++){

for(int j = i + 1; j < array.size() ;j++)

 {

    int first = array[i];

    int second = array[j];

    //Do someting.

 }

}
