Given an enum with 4 elements
enum fontType {bold,italic,underlined,struck} and two variables of this enumeration type called enum1 and enum2 that are assigned as follows
fontType enum1=fontType.bold | fontType.italic; fontType enum2=fontType.underlined & fontType.struck; Why is enum1 = 'italic' and enum2 = 'underlined' on output?
If you're going to use the enum as a bitmap like this, then the members need to be given values which use a different bit each:
[Flags] enum MyEnum { Bold = 0x01, Italic = 0x02, Underlined = 0x04, Struck = 0x08 } By default, they've been given the numbers 0,1,2,3 - the first does nothing, and the second two overlap with the last.
As mentioned in the comments, you should also add the [Flags] attribute to the enum definition, so that if you do ToString() you get a properly formatted result (and so that everybody knows how you're using the enum) - if won't affect the way it works if you don't, though.
