C# Programmatically make enum
-1
I'd like ask is there any method to make enum with string array.
for example, usually we make enum like this.
public enum Temp {
aa = 0,
bb,
cc,
dd
}
What I wish to know is, how to convert String array to enum programmatically.
String Temp = { aa, bb, cc, dd }
to above one ( String to enum ).
is it possible?
if then, how can I do this?

Please be very specific, Do you want to convert a string array to anenumarray. or do you want create a newenumbased on a string array? In the case of the later, it doesnt make any sense what-so-ever. how would you even write further code for it. What i am guessing you want, is maybe aDictionary<string,int>

You can’t create an enum programmatically because an enum is created at compile time and your program doesn’t run until run time.

Dictionary<string,int>most likely, depending on your needs, example usagevar myInt = myDict["aa"]orif(someValue == myDict[someKeyFormArray])ect ect

Yes you can programmatically do this. You will have to look into System.CodDom theres a bunch of material that has to be covered so I didn't write a answer to the question.

I would be curious what you would want to do with this, but you can create a new enum type at runtime.
private static Type BuildEnum(string enumValues, string enumName)
{
AssemblyName aName = new AssemblyName("TempAssembly");
AssemblyBuilder ab = AppDomain.CurrentDomain.DefineDynamicAssembly(
aName, AssemblyBuilderAccess.RunAndSave);
var eb = ab.DefineDynamicModule(aName.Name, aName.Name + ".dll").DefineEnum(enumName, TypeAttributes.Public, typeof(int));
for (int i = 0; i < enumValues.Length; i++)
{
eb.DefineLiteral(enumValues[i], i);
}
return eb.CreateType();
}
var myEnum = BuildEnum(new string { "aa", "bb", "cc", "dd" }, "Temp");
var enumValues = Enum.GetValues(myEnum)
