Verbatim string literals v escape sequences

Solution 1:

Any difference here is limited strictly to the compiler; the IL and runtime have no concept of verbatim vs escaped - it just has the string.

As for which to choose: whichever is more convenient ;p I almost always use verbatim string literals if there are unusual characters, as that allows for multi-line strings very easily and visually.

As an interesting case:

bool areSame = ReferenceEquals("c:\\somewhere", @"c:\somewhere"); // true

which tells are they are exactly the same string instance (thanks to "interning"). They aren't just equivalent; they are the same string instance to the runtime. It is therefore impossible that they can be (to the runtime) different in any way.

Solution 2:

They are exactly the same. Try to decompile the two versions with a decompiler.

It's only a matter of convenience for developers when writing it in the code.
