Hi all,
I have always approximately read everywhere that "Once created a string cannot be changed ". Well, can anyone tell me with examples, what is the problem when we declare a string like this :-

string s1 = "Akiii";
string s1 = "Lethal";

Is "s1" getting re-assigned to a newer value or is it creating a different string object s1 and assigning a different value ?

Thanks and Regards
Akiii

0	Hi, You can reassign value to S1, but do not repeat the declaration. try like this string s1 = "Akiii"; s1 = "Lethal"; Blessy Baby Digitalmesh Softech pvt Ltd https://blessybaby.wordpress.com/ Akiii, if this helps please login to Mark As Answer. \| Alert Moderator

0	Hi blessy, Thank you for your reply. Is "s1" been re-assigned to a different value here ? if it is the case then what is the statement telling us "Once created a string cannot be changed" ? Regards Akiii Akiii, if this helps please login to Mark As Answer. \| Alert Moderator

0	Hi first you assign a value for the s1 string variable internally it will assign some memory to that value . if you reassign a value to the s1 variable then internally s1 release the memory to the garbage collection then when you assign the new value it will again create a memory for new value. hope it will justfy your statement "Once created a string cannot be changed.
