In .NET prior to version 2.0, "" creates an object while string.Empty creates no object^ref, which makes string.Empty more efficient.

In version 2.0 and later of .NET, all occurrences of "" refer to the same string literal, which means "" is equivalent to .Empty, but still not as fast as .Length == 0.

.Length == 0 is the fastest option, but .Empty makes for slightly cleaner code.

See the .NET specification for more information.

In .Net pre 2.0, "" creates an object while String.Empty creates no object. So it is more efficient to use String.Empty.

.Length == 0 is the fastest option, but .Empty makes for slightly cleaner code.

As @chadmyers mentioned, in version 2.0 and above of .Net, all occurrences of "" refer to the same string literal.

So "" is pretty equivalent to .Empty, but still not as fast as .Length == 0.
