Why do I get “cannot be accessed with an instance reference” when using teststring.Join but not teststring.Split? (c#)

Question

I\'m learning c# and there is something I do not understand that I\'ve been unable to find any help about online.

string[] = testarray = { \"test1\", \"test2         


        

Answer 1

I would assume its because the method is not directly related to the String reference in any way and in order to avoid any confusion they made it a static method of String instead, whereas Split is directly related as you're splitting that particular String instance.
