Méthodes publiques

Méthode	Description
Canonicalize ( string source, int startIndex ) : string	Take a possibly escaped character literal and convert it to a canonical form. Thus @"'\377'", @"'\xff'" and @"'\u00FF'" all return @"'\xFF'". Throws a StringInterpretException if character ordinal exceeds "symLimit".
InterpretCharacterEscapes ( string source ) : string	This static method expands characters in a literal string, returning a modified string with character escapes replaced by the character which they denote. This includes characters outside the BMP which return a pair of surrogate characters.
InterpretEscapesInVerbatimString ( string source ) : string	This static method expands characters in a verbatim string, returning a modified string with character escapes replaced by the character which they denote.
Map ( int code ) : string	Map literal characters into the display form
Map ( string source ) : string
MapForCharSet ( int code ) : string	Same as Map(code) except '-' must be escaped.
OrdinalOfCharLiteral ( string source, int offset ) : int	Take the string representation of a possibly backslash- escaped character literal and return the character ordinal. Throws a StringInterpretException if character ordinal exceeds "symLimit".
QuoteMap ( int code ) : string
QuoteMap ( string source ) : string

Method Details

Canonicalize() public static méthode

Take a possibly escaped character literal and convert it to a canonical form. Thus @"'\377'", @"'\xff'" and @"'\u00FF'" all return @"'\xFF'". Throws a StringInterpretException if character ordinal exceeds "symLimit".

public static Canonicalize ( string source, int startIndex ) : string
source	string
startIndex	int
Résultat	string

InterpretCharacterEscapes() public static méthode

This static method expands characters in a literal string, returning a modified string with character escapes replaced by the character which they denote. This includes characters outside the BMP which return a pair of surrogate characters.
