Strings consist of sequences of characters contained in string object. A string object may be created using a number of different mechanisms.

A string may be declared but not initialized as follows:

String literals are placed with double quotes (as shown above). If the string itself contains double quotes the escape character (\) should precede the double quote characters:

It is possible to access individual characters in a string by treating the string as an array (for details on C# arrays read the chapter entitled [[Introducing C Sharp Arrays|Introducing C# Arrays]]).

By specifying the index into the array of the character individual characters may be accessed. It is important to note that strings are immutable (in other words the value of a string cannot be modified unless an entirely new string literal is assigned to the object). This means that while it is possible to read the value of a character in a string it is not possible to change the value:
