Difference Between StringBuilder and String

Difference Between String and String

String


1.Its a class used to handle strings.
2.Here concatenation is used to combine two strings.
3.String object is used to concatenate two strings.
4.The first string is combined to the other string by creating a new copy in the memory as a string object, and then the old
string is deleted
5.That is why  "Strings are immutable".
6. Slower

String Builder

1.This is also the class used to handle strings.
2.Here Append method is used.
3.Here, Stringbuilder object is used.
4.Insertion is done on the existing string.
5.Usage of StringBuilder is more efficient in case large amounts of string manipulations have to be performed.
6. Faster



class
Program
{
static void Main(string[] args)
{
//for example:

string str = "hello"; //Creates a new object when we concatenate any other words along with str variable it does not actually modify the str variable, instead it creates a whole new string.
str = str + " to all";
Console.WriteLine(str);
StringBuilder s = new StringBuilder("Hi");
s.Append(" To All");
Console.WriteLine(s);
Console.Read();
}
}
