return new string vs .ToString()
- by Leroy Jenkins
Take the following code:
public static string ReverseIt(string myString)
{
char[] foo = myString.ToCharArray();
Array.Reverse(foo);
return new string(foo);
}
I understand that strings are immutable, but what I dont understand is why a new string needs to be called
return new string(foo);
instead of
return foo.ToString();
I have to assume it has something to do with reassembling the CharArray (but thats just a guess).
Whats the difference between the two and how do you know when to return a new string as opposed to returning a System.String that represents the current object?
