Points to learn from this program
1. C# defines the following character escape sequences:
\' – single quote, needed for character literals.
\" – double quote, needed for string literals.
\\ – backslash.
\0 – Unicode character 0.
\a – Alert
\b – Backspace
\f – Form feed
\n – Newline
\" – double quote, needed for string literals.
\\ – backslash.
\0 – Unicode character 0.
\a – Alert
\b – Backspace
\f – Form feed
\n – Newline
Additionally, with these escape sequences, any characters proceeding with \ will be considered as escape sequences by C# compiler and start to throw compile-time errors.
For example, \s \u \d will be considered as an invalid escape sequence even a programmer wants to use these character combinations intentionally. It can be avoided by using verbatim literals.
3. Basically, the @ symbol tells the string constructor to ignore escape characters and line breaks.
Hint:
Try to remove @ symbol from
string userLoc = @"C:\users\User1\User1Folder";
check what type of error you are getting.
