Compare multiple documents with specific compare settings Leave feedback

Note

NOTE: This feature available only for Microsoft Word documents, Microsoft PowerPoint and Open Document presentations.

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.

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);
}

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);
}
