string

The string type represents a string of Unicode characters. string is an alias for System.String in the NGWS Framework.

Although string is a reference type, the equality operators (== and !=) are defined to compare the values of string objects, not references (§ 7.9.7 in the language reference). This makes testing for string equality more intuitive.

string a = "hello";
string b = new string( "hello" );
Console.WriteLine( a == b );  // output: True -- same value
Console.WriteLine( (object)a == b ); //  False -- different objects

The + operator concatenates strings:

string a = "good " + "morning";

The [] operator accesses individual characters of a string:

char x = "test"[2];  // x = 's';

String literals are of type string and can be written in two forms, quoted and @-quoted. Quoted string literals are enclosed in double quotation marks ("):

"good morning"   // a string literal

and can contain any character literal, including escape sequences:

string a = "\\\u0066\n";  // backslash, letter f, new line

@-quoted string literals start with @ and are enclosed in double quotation marks. For example:

@"good morning"  // a string literal

The advantage of @-quoting is that escape sequences are not processed, which makes it easy to write, for example, a fully qualified file name:

@"c:\Docs\Source\a.txt"  // rather than "c:\\Docs\\Source\\a.txt"

To include a double quotation mark in an @-quoted string, double it:

@"""Ahoy!" cried the captain." // "Ahoy!" cried the captain.

Example

using System;
class test {
   public static void Main( String[] args ) {
      string a = "\u0068owdy ";
      string b = "doody";
      Console.WriteLine( a + b );
      Console.WriteLine( a + b == "howdy doody" );
   }
}

Output

howdy doody
True
