RegEx ; GroupNames ; fill in the dictionary.

Question

Hello experts, I need your help.

I have this input and want to fill a dictionary.
The group names can be more or less.

My solution works, but is not well solved.
How can I make it better, which would be the question.
Thank you.

//text = "[)>@06@PTVK1281257@21P@3SID-214214@@";     should also possible empty string 21P is empty, no value however.
