Sharepoint Multiple Values Column?

I want to create a custom field with multiple 开发者_运维问答values like it may store array variables. also this field is not a lookup field.

what can be the field type that I should inherit from to achieve this ?

thanks

SPFieldMultiColumn may well be the class you're looking for. Here is the relevant MSDN article: http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.spfieldmulticolumn.aspx

Good luck with it though, custom fields can be a pain in the ears at the best of times.
