    @ explanation pls

    can someone explain what the @ symbol does in the following:
    Code:
    [DllImport(@"setupapi.dll", CharSet = CharSet.Auto, SetLastError = true)]
    I've been seeing this a few times in other examples codes on completely different topics but always added beofre strings.

    Compilers can produce warnings - make the compiler programmers happy: Use them!

    It's a verbatim string, in this case, the same as had someone said "setupapi.dll" - There are no escapes inside a verbatim string, except for double quotes (which is "". not \"). My guess is that MS is finally tired of typing: "\\\\SERVER\\share\\path\\file" - @"\\SERVER\share\path\file"
    long time; /* know C? */
    Unprecedented performance: Nothing ever ran this slow before.
    Any sufficiently advanced bug is indistinguishable from a feature.

    i find it useful for regex as well.

    but p/Invoke works fine without that symbol.

    Thanks everyone else.
