The string class provides members for comparing strings, testing strings for equality, finding characters or substrings in a string, modifying a string, extracting substrings from a string, combining strings, formatting values, copying a string, and normalizing a string. Learn about strings in c# programming See information on declaring and initializing strings, the immutability of string objects, and string escape sequences. The following example demonstrates how to create a new string object from a portion of a character array, and how to create a new string object that contains multiple occurrences of a single character. The class string includes methods for examining individual characters of the sequence, for comparing strings, for searching strings, for extracting substrings, and for creating a copy of a string with all characters translated to uppercase or to lowercase. The string class is an instantiation of the basic_string class template that uses char (i.e., bytes) as its character type, with its default char_traits and allocator types (see basic_string for more info on the template).
The string class is defined in the.net base class library In other words, a string object is a sequential collection of system.char objects, which represent a string. The xref:system.string class provides members for comparing strings, testing strings for equality, finding characters or substrings in a string, modifying a string, extracting substrings from a string, combining strings, formatting values, copying a string, and normalizing a string. An email address has different properties to a string Name@example.net can be an email address and a string, fish can not be an email address A hostname property or a checkmxrecord method makes more sense for an email address than a string.
