Is string actually an array of chars or does it just have an indexer?

Question

As the following code is possible in C#, I am intersted whether string is actually an array of chars:

string a=\"TEST\";
char C=a[0]; // will be T
         


        

Answer 1

A string is not a char[], although it does have a .ToCharArray(). Also it does have an indexer, which allows you to access characters individually, like you've shown. It is likely that it was implemented with an array internally, but that's an implementation detail.
