The second approach is to use 'verbatim string' literals. These are defined
by enclosing the required string within a leading at-sign and two double
quotes (@"string").To illustrate this, to set the variable 'path' to the
following value:
C:\My Documents\
we could either escape the back-slash characters
string path = "C:\\My Documents\\"
or use a verbatim string thus:
string path = @"C:\MyDocuments\"
Strings written using the verbatim string syntax can span multiple lines,
and whitespace is preserved. The only character that needs escaping is the
double-quote character, the escape sequence for which is two double-quotes
together. For instance,
suppose that you want to set the variable 'text' to the following value:
the word "big" contains three letters.
Using the verbatim string syntax, the command would look like this:
string text = @"the word ""big"" contains three letters."
