Is string.Length in C# (.NET) instant variable?

Question

I\'m wondering if string.Length in C# is an instant variable. By instant variable I mean, when I create the string:

string A = \"\";

A = \"Som          


        

Answer 1

The length of the string is not computed, it is known at construction time. Since String is immutable, there will be no need for calculating it later.

A .NET string is stored as a field containing the count of characters, and a corresponding series of unicode characters.
