Cast Int Array to Enum Flags

Question

I have the following enum with flags:

[Flags]
public enum DataFiat {
  Public = 1,
  Listed = 2,
  Client = 4
} // DataFiat

And I have an int array, for example:

int[] selected = new int[] { 1, 4 }

How can I convert this to my enum which would become:

DataFiat.Public | DataFiat.Client

Thank You, Miguel

Answer 1

var f = (DataFiat)selected.Sum();

Answer 2

How about something like

var tt = (DataFiat)selected.Aggregate((i, t) => i | t);

Answer 3

this snippet:

        var intArr = new[] { 1, 4 };
        var sum = intArr.Sum(x => x);
        var result = (Test)sum;

returns
