Examples
Shows how to specify which document shall be used as a target during comparison.
// Create our original document
Document docOriginal = new Document();
DocumentBuilder builder = new DocumentBuilder(docOriginal);

// Insert paragraph text with an endnote
builder.Writeln("Hello world! This is the first paragraph.");
builder.InsertFootnote(FootnoteType.Endnote, "Original endnote text.");

// Insert a table
builder.StartTable();
builder.InsertCell();
builder.Write("Original cell 1 text");
builder.InsertCell();
builder.Write("Original cell 2 text");
builder.EndTable();

// Insert a textbox
Shape textBox = builder.InsertShape(ShapeType.TextBox, 150, 20);
builder.MoveTo(textBox.FirstParagraph);
builder.Write("Original textbox contents");

// Insert a DATE field
builder.MoveTo(docOriginal.FirstSection.Body.AppendParagraph(""));
builder.InsertField(" DATE ");

// Insert a comment
Comment newComment = new Comment(docOriginal, "John Doe", "J.D.", DateTime.Now);
newComment.SetText("Original comment.");
builder.CurrentParagraph.AppendChild(newComment);

// Insert a header
builder.MoveToHeaderFooter(HeaderFooterType.HeaderPrimary);
builder.Writeln("Original header contents.");

// Create a clone of our document, which we will edit and later compare to the original
Document docEdited = (Document)docOriginal.Clone(true);
Paragraph firstParagraph = docEdited.FirstSection.Body.FirstParagraph;

// Change the formatting of the first paragraph, change casing of original characters and add text
firstParagraph.Runs[0].Text = "hello world! this is the first paragraph, after editing.";
firstParagraph.ParagraphFormat.Style = docEdited.Styles[StyleIdentifier.Heading1];

// Edit the footnote
Footnote footnote = (Footnote)docEdited.GetChild(NodeType.Footnote, 0, true);
footnote.FirstParagraph.Runs[1].Text = "Edited endnote text.";

// Edit the table
Table table = (Table)docEdited.GetChild(NodeType.Table, 0, true);
table.FirstRow.Cells[1].FirstParagraph.Runs[0].Text = "Edited Cell 2 contents";

// Edit the textbox
textBox = (Shape)docEdited.GetChild(NodeType.Shape, 0, true);
textBox.FirstParagraph.Runs[0].Text = "Edited textbox contents";

// Edit the DATE field
FieldDate fieldDate = (FieldDate)docEdited.Range.Fields[0];
fieldDate.UseLunarCalendar = true;

// Edit the comment
Comment comment = (Comment)docEdited.GetChild(NodeType.Comment, 0, true);
comment.FirstParagraph.Runs[0].Text = "Edited comment.";

// Edit the header
docEdited.FirstSection.HeadersFooters[HeaderFooterType.HeaderPrimary].FirstParagraph.Runs[0].Text =
    "Edited header contents.";

// When we compare documents, the differences of the latter document from the former show up as revisions to the former
// Each edit that we've made above will have its own revision, after we run the Compare method
// We can compare with a CompareOptions object, which can suppress changes done to certain types of objects within the original document
// from registering as revisions after the comparison by setting some of these members to "true"
CompareOptions compareOptions = new CompareOptions

    IgnoreFormatting = false,
    IgnoreCaseChanges = false,
    IgnoreComments = false,
    IgnoreTables = false,
    IgnoreFields = false,
    IgnoreFootnotes = false,
