Answer 2

yes, assuming I have a "FieldInfo"

bool tIsEnum=pInfo.FieldType.IsEnum; // (that is the function in regular .NET reflection)

pInfo is a valid FieldInfo I got from "foreach (PropertyInfo pInfo in PropertyInfoArray)"

Answer 3

Can you get to the TypeInfo (GetType().GetTypeInfo()) which I believe has IsEnum (not near my machine right this moment)

Answer 4

Aha! Yes, that works. Looks like this is an extra step necessary in Metro.

Answer 5

now there is no GetTypeInfo() anymore.. what to do now to find out if a System.Type is an Enum Type?

Thanks

Answer 6

GetTypeInfo is there...I'm not sure why you don't think it is.

Answer 7

Hmm..I

've got a Portable Class Library in VS 2012 Pro running in Win 8 Pro (both no preview versions.. dreamspark premium)
while creating i checked: .net4.5 and .net for windows store apps (no silverlight, no phone)

thats all..

here is the sample project: http://sdrv.ms/OBRvZu

Thanks

Answer 8

For portable libraris you should still be able to use <Type>.GetType().IsEnum.

Answer 9

nope.. nothing there..
i can see IsArray and so on, but no enum

Answer 10

Weird, I just created a portable class library and did a this.GetType().IsEnum, no problem

Answer 11

Which platforms did you choose? maybe its because of the combo .net + store  without phone and 360

Answer 12

I tested a view combinations..

the problem is because of the "store target" .. even if you create a class library for windows store (non portable) you don't have TypeInfo or IsEnum :(

Do you have any other idea?

Thanks!

Answer 13

This works fine in a Store class library (non portable).  You need to ensure you are using the extension method:

using System.Reflection; // to get the extension method for GetTypeInfo()

var foo = this.GetType().GetTypeInfo().IsEnum;
