C# Converting set flags in a variable of type flag enumeration to an array of integers

Answer 1

Just cast to an int, and then print out individual bits.

int x = (int)o
List<int> flags = new List<int>();
for(int i = 1; i < (1 << 30); i <<= 1)
    if(x & i != 0)
        flags.Add(i);
return flags;

Answer 2

Well, you can replace steps 1-3 with a call to Enum.GetValues. And then use the bitwise & operator to test which of those are set in your value. This will be much faster than working with strings.

This method will support flags which are more than a single bit wide. If all bits are independent, just do what Anon said.

Answer 3

To keep it linq-like

var flags = Enum.GetValues(typeof(Status))
                .Cast<int>()
                .Where(f=> f & o == f)
                .ToList();
