Get list of changes

GroupDocs.Comparison allows you to get list of changes between source and target documents.

To get list of changes, follow these steps:

  1. Instantiate the Comparer object. Specify the source document path or stream.
  2. Call the Add method. Specify the target document path or stream.
  3. Call the Compare method.
  4. Call the GetChanges method.

The following code snippets show how to get list of all changes:

Get list of changes from local disk

using (Comparer comparer = new Comparer("source.docx"))
{
	comparer.Add("target.docx");
    comparer.Compare();
    ChangeInfo[] changes = comparer.GetChanges();
    foreach (ChangeInfo change in changes)
    Console.WriteLine("Change Type: {0}, Page: {1}, Change ID: {2}, Text: {3}", change.Type, change.PageInfo.PageNumber, change.Id, change.Text);
}

The result is as follows:

Get list of changes from stream

using (Comparer comparer = new Comparer(File.OpenRead("source.docx")))
{
	comparer.Add(File.OpenRead("target.docx"));
    comparer.Compare();
    ChangeInfo[] changes = comparer.GetChanges();
    foreach (ChangeInfo change in changes)
        Console.WriteLine("Change Type: {0}, Page: {1}, Change ID: {2}, Text: {3}", change.Type, change.PageInfo.PageNumber, change.Id, change.Text);
}
