RE: What is the difference between string class and stringbuilder class?
String is immutable where as stringbuilder is mutable.

That means: The value in a string can not be modified once it has been created. When you modify a string in your code it actually creates a new string with the modified value and the string object only starts to reference this new (modified) string. That is why .Net has System.Text.StringBuilder class (to modify the string). So if you need to change the value in your string heavily you should use the StringBuilder.

But you should not use the StringBuilder everytime as it will take a toll on the performance of your application
