Migration Notes

Why To Migrate?

Here are the key reasons to use the new updated API provided by GroupDocs.Comparison for .NET since version 19.9:

  • Comparer class introduced as a single entry point to compare documents of any supported file format with various options and ability to accept/reject found differences in resultant document.
  • Document compare options for all document types. Instead of using document related options now options are related to compare type only.
  • The overall document related classes were unified to common.
  • Product architecture was redesigned from scratch in order to simplify passing options and classes to manipulate comparison.
  • Document information and preview generation procedures were simplified.

How To Migrate?

Here is a brief comparison of how to compare document with old and new API.

Old coding style

Comparer comparer = new Comparer();
ComparisonSettings settings = new ComparisonSettings()
	StyleChangeDetection = true
ICompareResult result = comparer.Compare("source.docx", @"target.docx", settings);

New coding style

using (Comparer comparer = new Comparer("source.docx"))
    CompareOptions compareOptions = new CompareOptions()
        DetectStyleChanges = true
	comparer.Compare("result.docx", compareOptions);
