Error - can not create enum dynamically
-
Hi All, I am trying to create Enum Dynamically. When I try to Save dll It gives me error - "Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))" I am also writing code snippet :- AppDomain currentDomain = AppDomain.CurrentDomain; AssemblyName aName = new AssemblyName("TempAssembly"); AssemblyBuilder ab = currentDomain.DefineDynamicAssembly(aName, AssemblyBuilderAccess.RunAndSave); ModuleBuilder mb = ab.DefineDynamicModule(aName.Name, aName.Name + ".dll"); EnumBuilder eb = mb.DefineEnum("Elevation", TypeAttributes.Public, typeof(int)); eb.DefineLiteral("Low", 0); eb.DefineLiteral("High", 1); Type finished = eb.CreateType(); ab.Save(aName.Name + ".dll"); I got error at last line. I am working on Vista Premium. I gave permissions to Network Service User but still not solved. Please help me. your help is appreciated. Regards, Sdhimann

I am not getting the point of creating a dynamic enum in ASP.NET. AFAIK,
ab.Save()will save the files toAppDomain.CurrentDomain.BaseDirectory. What value are you getting inAppDomain.CurrentDomain.BaseDirectory? If the path you get is outside the website area, ASP.NET can't write to there.Navaneeth How to use google | Ask smart questions

If this code is all you are trying to do, then you are wasting your time. Just create the Enum class for you enumerator. On the other hand if this is a test for more complex process you should discuss this instead. For example, building enumerators from the database is a matter of Googling

Navaneeth, I have already answered him last night about the problem. I dont know why he is putting the same question again and again in the forum rather than replying the last replies. :-D :doh: :doh:
