Hi System.String is immutable. System.StringBuilder was designed with the purpose of having a mutable string where a variety of operations can be performed. StringBuilder is more Efficient in cases where there is large amount of string manipulation are required. Strings are Immutable so each time a string is changed a new instance in memory is created. If my answer helps you out please select it accepted. Cheers Kind regards Shakuntala
