Hi,
I have two references to the same string, like this:

string s1 = "One";
string s2 = s1;

s1 = "Two"; <--- s2 is still referencing to "One"

Now, I want that when I change the value of one variable (s1), the other
one (s2) is changed also. Can string behave like all other reference types?
Can it be done?

Thanx,
Cheya

You can't do that.

String already *does* behave like all other reference types. Changing
the value of one reference type variable doesn't change the value of
any other reference type variable. Note that there's a big difference
between changing the value of a variable and making a change within the
object that a variable's value refers to.

Well, you could write a StringHolder class which contained a reference
to a string and allowed it to be changed to a different reference. You
can't do it with plain string though.
