Compare multiple documents with specific compare settings

GroupDocs.Comparison allows to compare more that 2 documents and specify some specific comparison options like styling for detected changes, comparison detalisation level etc.

The following are the steps to compare multiple documents with specific options.

  • Instantiate Comparer object with source document path or stream;
  • Call Add method and specify target document path or stream. Repeat this step for every target document;
  • Instantiate CompareOptions object and specify desired options;
  • Call Comparer method and pass CompareOptions object from previous step.

The following code sample shows how to compare multiple documents with specific options.

Compare multiple documents with specific compare settings from local disk

using (Comparer comparer = new Comparer("source.docx")
{
	comparer.Add("target1.docx");
    comparer.Add("target2.docx");
    comparer.Add("target3.docx");
	CompareOptions compareOptions = new CompareOptions()
    {
    	InsertedItemStyle = new StyleSettings()
        {
        	FontColor = System.Drawing.Color.Yellow
        }
    };
    comparer.Compare("result.docx", compareOptions);
}

Compare multiple documents with specific compare settings from stream

using (Comparer comparer = new Comparer(File.OpenRead("source.docx"))
{
	comparer.Add(File.OpenRead("target1.docx"));
    comparer.Add(File.OpenRead("target2.docx"));
    comparer.Add(File.OpenRead("target3.docx"));
    CompareOptions compareOptions = new CompareOptions()
    {
    	InsertedItemStyle = new StyleSettings()
        {
        	FontColor = System.Drawing.Color.Yellow
        }
    };
    comparer.Compare(File.Create("result.docx"), compareOptions);
}
