How to Extract List of String into String Value

The problem is, after I Stored the list of String in One String using this strText = String.Join(“,”,strFilearr.toarray) It gives me the full path of Each Files, the reason why it throws some error.

I just wanted all files in one Folder and attached it in the email

Thank you, Please help me
