Question
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(intGetal
Console.ReadLine();
