23-Aug-2017System.String is immutable. When we modify the value of a string variable then a new memory is allocated to the new value and the previous memory allocation released.
System.StringBuilder was designed to have concept of a mutable string where a variety of operations can be performed without allocation separate memory location for the modified string.
