Replacing a Character in a String

[C# Learner]

What's the "standard" way of replacing a character in a string?
Obviously, I can't say "myString[index] = character;" because strings
are immutable...

So what would be the "standard" way of doing this?

TIA

OK, if the above is a no-no for you, then use the StringBuilder class.

myString = myString.Replace("xyz", "abc")

Dont know if there is necessarily a "standard" way, but here
is what I would do:

StringBuilder s = new StringBuilder("astringoftext");
s[11] = 'q';
string sNew = s.ToString();

sNew is now "astringofteqt"

and can now be assigned to the original string..

If you want to change one character with another one
use String.Replace

If you want to change one char at a certain index
use String.ToCharArray, do your change, then construct a new string from it
(not the most efficient way)

If it is necessary to modify the actual contents of a string-like object, use
the System.Text.StringBuilder class.
