Remarks

Each difference consists of a left span and a right span, either of which may have zero length (if the operation is an add operation or a delete operation). The text before and after the difference matches.

In general, differences are non-nulla null reference (Nothing in Visual Basic). However, when the difference appears at the beginning of the lists of differences, the "before" is nulla null reference (Nothing in Visual Basic), and when the difference appears at the end of the lists, the "after" is nulla null reference (Nothing in Visual Basic).

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
