Show gap lines instead of changes

GroupDocs.Comparison allows adjusting formation of the resulting document.

By default, changes from the two input files (source and target files) are added to the resulting document and visually highlighted. This can be configured using the ShowInsertedContent and ShowDeletedContent properties.

You can also use the LeaveGaps property to adjust the display of the resulting document, which allows to replace changed content with empty lines. To use this property, you also need to activate the following properties: ShowInsertedContent and ShowDeletedContent.

Here are the simple steps to get the above result:

Example code block to get the desired result

using (Comparer comparer = new Comparer(sourcePath))
    CompareOptions options = new CompareOptions();
    options.ShowInsertedContent = false;
    options.ShowDeletedContent = false;
    options.LeaveGaps = true;
    comparer.Compare(resultPath, options);

Example code execution
