Unrecognized Escape sequence

static string path="C:\Path";

What is the reason of this error and how can I solve this????

Answer 1

You need to escape the '\' with another '\', like so:

static string path="C:\\Path";

or put an '@' in front of it like so:

static string path = @"C:\Path";

Answer 2

This is because a backslash in C# is used to mark the next character as its literal interpretation. For example if you wanted a quote inside your string you would precede it with \ to prevent the string being closed early:

var myString = "This is my string with \"quotes\"";

This is called escaping. In order to display a blackslash within a string you either need to escape it with another slash:

static string path = "C:\\Path";

Or precede the string with the @ symbol, which suppresses the backslash escape mechanism:

static string path = @"C:\Path";
