What's the meaning of "|" and "@" in C#?

[Ming Luo]

Dear All: Could anyone give me some useful articles about introducing the symbol "|" and "@" in C# please? For example, I saw a code something like:

FileSystemWatcher fsm = new FileSystemWatcher(Environment.GetEnvironmentVariable("USERPROFILE"));

fsm.NotifyFilter = NotifyFilters.FileName | NotifyFilters.LastWrite;

Thanks

The "|" means "or", can be found here[^]. The "@" symbol is mostly used with strings[^] :)

I think this two characters have nothing in common.

'|' is logical "OR' operator. '@' is used with strings to avoid escape characters. you can use like @"c:\hello.cs" ; instead of adding escape character for '\\'

'|' is bitwise 'OR' operator for integers (also logical 'OR' operator for booleans) '||' is logical 'OR' operator for booleans :)

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.
