Hi, I like to create hashtables from a string array haviong all possible combinations. I guess i will give examples to better explain my problem. suppose there is a string array which we call matrix in mathematics 1 2 3 4 5 6 7 8 9 Now the combinations should be cerated and each combination will go in one hashtable (1,4,7) (1,4,8) (1,4,9) (1,5,7) (1,5,8) (1,5,9) (1,6,7) (1,6,8) (1,6,9) (2,4,7) (2,4,8) (2,4,9) (2,5,7) (2,5,8) (2,5,9) (2,6,7) (2,6,8) (2,6,9) (3,4,7) (3,4,8) (3,4,9) (3,5,7) (3,5,8) (3,5,9) (3,6,7) (3,6,8) (3,6,9) Also the matrix can be of any dimension and not just 3*3 it can be of 3*2 or 4*5 or 4*4 Please help me writting the code in c# to generate the above combinations. Thanks in advance.

If I understand just take a 2 Dimensional array of (N x M) and initialize all to some impossible input (say -1) now nested loop through them to get the combination. Can you put your code sample you are working on here.
