Handling bitmask values

Hello,

I'm searching for a logical syntax or method for handling following problem.

I have 3 values in bitmask format:
1 = A
2 = B
4 = C

Possible values are: 1, 2, 3, 4, 5, 6 and 7.

Now I want a kind of for-each-loop to insert the values A, B and/or C in the database.

Example 1:
Incoming value = 1
Single insert into database: A

Example 2:
Incoming value = 7
Three inserts into database: A, B and C.

What is the fastest way to do this in C# .net?

Thanks in advance.

I've found it:

                double intGetal;
                double inti;
                int intJ;
                double[] intGetallen = new double[3];
                double intWaarde;

                intGetal = 7;

                intJ = 0;

                for (inti = 2; inti >= 0; inti = inti - 1)
                {

                    intWaarde = intGetal - Math.Pow(2, inti);
                    if (intWaarde >= 0)
                    {
                        intGetal = intGetal - Math.Pow(2, inti);
                        intGetallen[intJ] = Math.Pow(2, inti);
                        intJ = intJ + 1;
                    }
                }

                Console.WriteLine(intGetallen[0] + " - " + intGetallen[1] + " - " + intGetallen[2]);
                Console.ReadLine();
