Enum for possible values of HyperLink.Target

Maybe kind of a noob .NET question, but is there an enum that represents the possible values for HyperLink.Target (e.g. "_bl开发者_运维知识库ank", "_top", etc)?

There's no ready-made enum. Probably because (besides the special values starting with _) target can contain the name of a specific frame where it has to open the document

No, there is no built-in enum for this in the .NET Framework. You have to create it yourself. :)
