That was my assumption, too. They do memoize the length, but I'm sure those bytes add up, having run into OutOfMemoryExceptions building huge amounts of strings before.

Strings know their length in the CLR because they are represented as BSTRs

You have to store the length, C# strings can contain '\0' (although the hashing code doesn't take this into account!)
