Question: I have an enum that I'd like to display all possible values of. Is there a way to get an array or list of all the possible values of the enum instead of manually creating such a list? e.g. If I have an enum:

```
public enum Enumnum { TypeA, TypeB, TypeC, TypeD }

```

how would I be able to get a `List<Enumnum>` that contains `{ TypeA, TypeB, TypeC, TypeD }`?

Answer: 
You may want to do like this:

```
public enum Enumnum { 
            TypeA = 11,
            TypeB = 22,
            TypeC = 33,
            TypeD = 44
        }

```

All int values of this `enum` is `11,22,33,44`.

You can get these values by this:

```
var enumsValues = Enum.GetValues(typeof(Enumnum)).Cast<Enumnum>().ToList().Select(e => (int)e);

```

`string.Join(",", enumsValues)` is `11,22,33,44`.
also you can use

```
var enumAsJson=typeof(SomeEnum).Name + ":[" + string.Join(",", Enum.GetValues(typeof(SomeEnum)).Cast<SomeEnum>().Select(e => e.ToString())) + "]";

```

for get all elements in enum as json format.
