Recently i found out i can write in a \" by writing two \" ex @\"abc\"\"def\". I find the @ string literal useful. But how do i write in a tab or n
None of the normal escape sequences work in verbatim string literals (that's the point!). If you want a tab in there, you'll either have to put the actual tab character in, or use string concatenation:
string x = @"some\stuff" + "\t" + @"some more stuff";
What are you using a verbatim string literal for in the first place? There may be a better way of handling it.
