Regex escape with \ or \\?

Question

Can someone explain to me when using regular expressions when a double backslash or single backslash needs to be used to escape a character?

A lot of references onli

Answer 1

\ Is also an escape character for string literals in c# so the first \ is escaping the second \ being passed to the method and the second one is escaping the . in the regex.

Use:

if (Regex.IsMatch(myString, @"SomeString\."))

If you want to avoid double escaping.
