Get the differences by comparing two Word documents in C#/VB.NET
2021-01-04 07:37:21 Written by AdministratorWe have introduced how to compare two Word documents in C# and VB.NET. From Spire.Doc V8.12.14, it supports to get the differences between two Word documents in a structure list. This article will show you how to use Spire.Doc to get the differences by comparing two Word documents.
C#
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using Spire.Doc.Formatting.Revisions;
using System;
namespace GetWordDifferences
{
class Program
{
static void Main(string[] args)
{
//Load the first Word document
Document doc1 = new Document();
doc1.LoadFromFile("Sample1.docx");
//Load the second Word document
Document doc2 = new Document();
doc2.LoadFromFile("Sample2.docx");
//Compare the two Word documents
doc1.Compare(doc2, "Author");
foreach (Section sec in doc1.Sections)
{
foreach (DocumentObject docItem in sec.Body.ChildObjects)
{
if (docItem is Paragraph)
{
Paragraph para = docItem as Paragraph;
if (para.IsInsertRevision)
{
EditRevision insRevison = para.InsertRevision;
EditRevisionType insType = insRevison.Type;
string insAuthor = insRevison.Author;
DateTime insDateTime = insRevison.DateTime;
}
else if (para.IsDeleteRevision)
{
EditRevision delRevison = para.DeleteRevision;
EditRevisionType delType = delRevison.Type;
string delAuthor = delRevison.Author;
DateTime delDateTime = delRevison.DateTime;
}
foreach (ParagraphBase paraItem in para.ChildObjects)
{
if (paraItem.IsInsertRevision)
{
EditRevision insRevison = paraItem.InsertRevision;
EditRevisionType insType = insRevison.Type;
string insAuthor = insRevison.Author;
DateTime insDateTime = insRevison.DateTime;
}
else if (paraItem.IsDeleteRevision)
{
EditRevision delRevison = paraItem.DeleteRevision;
EditRevisionType delType = delRevison.Type;
string delAuthor = delRevison.Author;
DateTime delDateTime = delRevison.DateTime;
}
}
}
}
}
//Get the difference about revisions
DifferRevisions differRevisions = new DifferRevisions(doc1);
var insetRevisionsList = differRevisions.InsertRevisions;
var deletRevisionsList = differRevisions.DeleteRevisions;
}
}
}

This article will demonstrate how to hide and display Layers in a PDF document using Spire.PDF for Java.
Hide all layers:
import com.spire.pdf.*;
import com.spire.pdf.graphics.layer.*;
public class invisibleAllPdfLayers {
public static void main(String[] args) {
//Load the sample document
PdfDocument doc = new PdfDocument();
doc.loadFromFile("layerSample.pdf");
for (int i = 0; i < doc.getLayers().getCount(); i++)
{
//Show all the Pdf layers
//doc.getLayers().get(i).setVisibility(PdfVisibility.On);
//Set all the Pdf layers invisible
doc.getLayers().get(i).setVisibility(PdfVisibility.Off);
}
//Save to document to file
doc.saveToFile("output/invisibleAllPdfLayers.pdf", FileFormat.PDF);
}
}
Hide some of the PDF layers:
import com.spire.pdf.*;
import com.spire.pdf.graphics.layer.*;
public class invisibleParticularPdfLayers {
public static void main(String[] args) {
//Load the sample document
PdfDocument doc = new PdfDocument();
doc.loadFromFile("layerSample.pdf");
//Hide the first layer by index
doc.getLayers().get(0).setVisibility(PdfVisibility.Off);
//Hide the layer by name with blue line1
for (int i = 0; i < doc.getLayers().getCount(); i++)
{
if("blue line1".equals(doc.getLayers().get(i).getName())){
doc.getLayers().get(i).setVisibility(PdfVisibility.Off);
}
}
//Save to document to file
doc.saveToFile("output/invisiblePaticularPdfLayers.pdf", FileFormat.PDF);
}
}

This article will demonstrate how to expand or collapse the bookmarks when viewing the PDF files.
Expand all bookmarks on PDF
import com.spire.pdf.PdfDocument;
public class expandBookmarks {
public static void main(String[] args) {
PdfDocument doc = new PdfDocument();
doc.loadFromFile("Sample.pdf");
//Set true to expand all bookmarks; set false to collapse all bookmarks
doc.getViewerPreferences().setBookMarkExpandOrCollapse(true);
doc.saveToFile("output/expandAllBookmarks_out.pdf");
doc.close();
}
}
Output:
Expand specific bookmarks on PDF
import com.spire.pdf.PdfDocument;
import com.spire.pdf.bookmarks.*;
public class expandSpecificBookmarks {
public static void main(String[] args) {
PdfDocument doc = new PdfDocument();
doc.loadFromFile("Sample.pdf");
//Set BookMarkExpandOrCollapse as "true" for the first bookmarks
doc.getBookmarks().get(0).setExpandBookmark(true);
//Set BookMarkExpandOrCollapse as "false" for the first level of the second bookmarks
PdfBookmarkCollection pdfBookmark = doc.getBookmarks().get(1);
pdfBookmark.get(0).setExpandBookmark(false);
doc.saveToFile("output/expandSpecificBookmarks_out.pdf");
doc.close();
}
}
Only expand the first bookmarks
