String in c#

C# | Strings:

• The range of Unicode characters will be U+0000 to U+FFFF.The array of characters is also termed as the text.
•  So the string is the representation of the text. 

• A string is represented by class System.String. The “string” keyword is an alias for System.String class and instead of writing System.String one can use String which is a shorthand for System.String class.
• So string is an object of System.String class.
