This service has several shortcut methods that compute differences over strings, snapshots, and spans.
Assembly: Microsoft.VisualStudio.Text.Data (in Microsoft.VisualStudio.Text.Data.dll)
|DiffSnapshotSpans(SnapshotSpan, SnapshotSpan, StringDifferenceOptions)|
Calculates the differences between two snapshot spans, using the given difference options.
|DiffStrings(String, String, StringDifferenceOptions)|
Calculates the differences between two strings, using the given difference options.
This is a MEF component part, and should be imported as follows:
[Import] Internal IHierarchicalStringDifferenceService hierarchicalService = null;
Differences are computed according to the specified StringDifferenceTypes, starting with the most general type. Line is more general than word, and word is more general than character.
Given string A:
This is a line!
and string B:
This is but a line!
The returned difference collection contains one line difference, which maps to line 1 of each string.
This difference contains one word difference, which is the addition of the words "but" and " ".
