Implementing System.String

Question

I recently tried to do the following in C #

string str = "u r awesome";
str[0]="i";

And this will not work, because, apparently, str [i] is just not a collection, so I was wondering if the main implementation of the string is to make str [i] only be get.

Isn't that just a managed shell for char *? So why can't I set str [i]?
