How to get the Enum item names using Reflection

[mcljava]

You can also simply do a ToString(). For example: string s = tenumArtMode.arModeManual.ToString(); Would yield the string "artModeManual" Good Luck Mike Luster CTI/IVR/Telephony SME

Thanks For your reply Mike, No, This can't be applicable, b'cas i getting this enum at runtime so i would not know the enum item names. Do understand my question. I want to iterate the enum using reflections Regards, Srini

You don't need reflection. The Enum class provides you with methods to get all information you nead about the enum. Use the GetNames method to get an array of all the names. If you need their values, use the GetValues method to get an array with all the values. --- b { font-weight: normal; }

If it is One Enum then your suggestions is OK. I can use Enum.GetNames(enum), But My situation is likes a structure which will contain lot of enums(say 100) as it member) so i can't write 100's lines of code to display every member ie. enum1 { a=0, b, c } .. enum100 { x=0, y, z } Struct st { enum1 e1; enum2 e2; .. enum100 e100; }; Enum.GetNames(st.e1); .. Enum.GetNames(st.e100); Instead Puting like the above I am thinking of reflection to reduce the line of code Like this Type ty = st.GetType(); FieldInfo[] fin= ty.GetFields(); foreach (FieldInfo fino in fin) { fino.GetValue(st).ToString(); } But This print the enum1..enum100 values like 0 0 0 0 .. but I want to print the enum member names like a b c ... Hope I Explained my question Clearyly Regards, Srini

I see. Try this, then: Enum.GetName(fino.FieldType, fino.GetValue(st)) --- b { font-weight: normal; }

[engsrini]

Exactly thats what i want, i have used the same code but it throws me me ArgumentException, i think since the enum is developed in VC++ .net fino.FieldType doesn't match with System.Enum Type in C#(since we are using Enum.GetName).. I think so. Try it out and if anything works please share with me. Regards, Srini

Have you tried it out? It's not the same code as you showed in your first post. --- b { font-weight: normal; }

[engsrini]

Yes I tried out. it throws me the ArgumentException. ArgumentException - Description given in the MSDN help enumType is not an Enum. -or- value is neither of type enumType nor does it have the same underlying type as enumType. Enum in VC++ .net and VC# .net are they different?

[engsrini]

Even That is code i have mentioned in my initial Conversation.

[Guffa]

No, it's not. There you used a Type object instead of a FieldInfo object. --- b { font-weight: normal; }

Have you tried using the Enum struct? Once you have the type of enum you can use the static methods of the Enum struct to obtain information about the enum type.:suss: chriswa

[engsrini]

I got it!!!! Thanks Chriswa its working as per your suggestion. i have declared the enum as enum class (ie enum struct) in VC++ dll. then i can able to get the enum member names. If i declare the enum using enum in VC++, then i am not able to retrieve the names. What is the difference between enum and enum struct I extend my thanks to Guffa. Regards,:-D Srini
