How to write an escape character in a string?

Question

How to write escape character "\" to string?

Answer 1

In the normal line you use \\

If it is in regular expression, it should be \\\\

The reason RegEx needs four is because both the line parser and the RegEx engine are accelerated. Therefore, it is \\\\parsed by String on \\and then on a literal \by the RegEx parser.

Answer 2

Eliminate the escape character: "\\"

Answer 3

, "\" .

\\ .

Answer 4

double\in string

String example = "C:\\Program Files";

Answer 5

string = @"c:\inetpub\wwwroot\"

 string = "c:\\inetpub\\wwwroot\\"

in some cases ... I'm not 100% sure, but I think it may be language dependent ... I KNOW "@" works in C #

Answer 6

You can write:

String newstr = "\\"; 

\ is a special character inside the string used for escaping.

"\"Now it works because it eludes the second ".

To get a literal \, you need to avoid it using \.
