How to retrieve multiple enum values?

[secutos]

Let's say I have an enumeration like so:

[Flags]
public enum Letters
{
A = 0,
B = 1,
C = 2,
D = 4,
E = 8
}

And let's say I have a variable like so:

Letters phrase = Letters.A | Letters.B | Letters.C;

How would I check to see if "phrase" contains Letter.A, Letter.B, and Letter.C individually?

e.g. The following code does not work:

if (phrase == Letters.A)
{
// some stuff...
}
if (phrase == Letters.B)
{
}

Solution

if ((phrase & Letters.A) == Letters.A)
{
// true
}
else
{
// false
}

You have to do a additive check for the bit

if ((phrase & Letters.A) == Letters.A)
{
   // You have a match
}

To make life easy and reduce typing you might want to make a method for checking

private bool IsLettersA(string CheckPhrase)
{
    if ((CheckPhrase & Leters.A) == Letters.A) return true;
    else return false
}

Now you can check like this

if (IsLettersA(Phrase))
{
   // So something if it is a match
}

You can do bitwise OR or AND
