In C#, what's the best way to spread a single-line string literal across multiple source lines?

Suppose that you have a lengthy string (> 80 characters) that you want to spread across multiple source lines, but don't want to include any newline characters.

One option is to concatenate substrings:

string longString = "Lorem ipsum dolor sit amet, consectetur adipisicing" +
    " elit, sed do eiusmod tempor incididunt ut labore et dolore magna" +
    " aliqua. Ut enim ad minim veniam";

Is there a better way, or is this the best option?

Edit: By "best", I mean easiest for the coder to read, write, and edit. For example, if you did want newlines, it's very easy to look at:

string longString =
@"Lorem ipsum dolor sit amet, consectetur adipisicing
elit, sed do eiusmod tempor incididunt ut labore et dolore magna
aliqua. Ut enim ad minim veniam";

I am wondering if there is something just as clean when you don't want newlines.
