code depending on build-type?

I'm using Visual c# Express 2008. I want to have a special command executed just in "Release" builds - this command should not be executed while I'm creating and running Debug versions. Is it possible to implement code depending on my build-type (Debug or. Release)?

For example:

if(??buildtype?? == "Release")
{
 //... special command ...
 MessageBox.Show("RELEASE version");
}
else
{
//... normal command ...
MessageBox.Show("debu开发者_StackOverflow中文版g release");
}

#if DEBUG
  // Commands that should run in debug builds.
#else
  // Commands that should run in release builds.
#endif
