What's the advantage of using System.Text.StringBuilder over System.String?..

Answer / prathap

StringBuilder is more efficient in the cases, where a lot of
manipulation is done to the text. Strings are immutable, so
each time it's being operated on, a new instance is created.

What's the advantage of using System.Text.StringBuilder over System.String?..

Answer / article

Hi..

Mutable & Immutable

1)string is immutabel.
i.e. whenever you create any changes to a string a new
object is created in memory.
2)StringBuilder has advantage String
To overcome this the stringBuilder is provided we can make
ammendments to the stringBuilder object without creating a
new object. Therefore whenever a lot operations are to be
made on a string then StringBuilder should be used in place
of String.

Answer / abhinay kumar

stiringbuilder is mutable but string is immutable

i.e mutable means that if we define a variable with
stringbuilder and assigne the value to another
stringbuilder variable and if we change the value then the
reflaction will be seen on the both variable (it made
change on the same memory location reference)

immutable means if we define a variable with string and
assigne the value to another string variable and if we
change the value then the reflaction will not be seen on
the both variable
