Hello, have you tried TestEnum.FromInteger ?
Because these methods are instance methods and not statics.

EDIT: my mistake, FromInteger is missing. AsInteger is the instance method.
By the way, the doc mentions Names and Ordinals as static methods, but like FromInteger, I do not see how these methods can be statics. It would mean that Enum.FromInteger returns some kind of "not typed enum"? What should we expect from Enum.Names or Enum.Ordinals to return (all the ordinals from all existing enums?

They are static methods on the specific enum type. E.g.

TestEnum := "Sales Document Type".FromInteger(1);

or

TestEnum := enum::"Sales Document Type".FromInteger(1);

Same for both Ordinals() and Names().

That makes sense, thanks!

The documentation is not clear in that case.

Considering the syntax Enum::"My Enum".Names() to be the static methods of the data type enum, we should be able to do Codeunit::"Sales Post".Run() as well.

The documentation should be clarified about that: methods on the data type Enum (or Codeunit) and methods on the strongly type data type Enum::"My Enum" (or Codeunit::"Sales Post".

There is a slight difference. The Codeunit.Run is a static method on the generic Codeunit class and run takes an argument that specifies what codeunit to run.

The static methods on the enum a related to a specific type of the enum.

We will update the enum documentation to be more clear on this.
