GetCustomAttributes FlagAttribute working only on some Enums

Question

I have a bit of code that checks an enum to see if it has [Flags]. however, It only works for one of the enums that has a flag. the other ones are ignored for some reason.
var currentEnum = new EnumInfo() { Name = t.Name, IsFlagsEnum = t.GetCustomAttributes<FlagsAttribute>().Any() };
It loads the enums from an assembly and iterates through them. Nothing seems to be completely different between the enums other than the name and the values inside.
the t is the element in the foreach loop
foreach (Type t in query)
What would cause the get custom attributes to fail to find the [flags] attribute. 

Answer 1

The OrderBy seems to work, since all of the Enums are in order once it returns. 
here's a couple of the enums, with scrubbed names. 
This one returns false for flags.
[Flags]
public enum Method
Undefined = 0,
Site = 1,
Manual = 2,
API = 4
and this one gets the boolean IsFlagsEnum = true;
[Flags]
public enum Type
New = 0,
Existing = 1
Hi
Fullmetal99012,
Thanks for posting more useful information, Now i have tried reproed your issue. As
CoolDadTx said, you code works fine on my side. Here is my screenshot
>>the only difference on the two enumerations I posted above is that the one that isn't getting picked up by the code is reporting that the "members" of the enum have a CustomAttribute, while the one that is shows 0 for the custom attribute
count. 
I doubt you put the Method enum as members of a class.
Best wishes,
Kristin
