I have a property on a custom control I have written that is an Flag based Enum. I created my own custom control to edit it in a way that makes logical sense and called it from
Using the Flags attribute on the enum will prevent the error from happening. This is a mystery to me as storing an ORed enum without the flag is valid and can be done in the code (With a proper cast).
You have to add [Flags]
before your enum declaration
[Flags]
public enum TrayModes
{
SingleUnit = 0x01
, Tray = 0x02
, Poll = 0x04
, Trigger = 0x08
};
Consider using HasFlag function to check for setted flags
TrayModes t=TrayModes.SingleUnit|TrayModes.Poll;
if(t.HasFlag(TrayModes.SingleUnit))
//return true
Edit: That's because enum with flags attribute are threated in a different way, as you can see in the example in http://msdn.microsoft.com/en-us/library/system.flagsattribute.aspx A To string of enum with and without Flags attribute show how they are different
All possible combinations of values of an Enum without FlagsAttribute:
0 - Black
1 - Red
2 - Green
3 - 3
4 - Blue
5 - 5
6 - 6
7 - 7
8 - 8
