Set password for resultant document Leave feedback

GroupDocs.Comparison allows to protect resultant document with password.

The following are the steps to protect resultant document:

• Instantiate Comparer object with source document path or stream;
• Call Add method and specify target document path or stream;
• Instantiate CompareOptions object with PasswordSaveOption = PasswordSaveOption.User;
• Instantiate SaveOptions object and set to Password property desired password for resultant document;
• Call Compare method and pass SaveOptions and CompareOptions  objects to a method.

The following code snippet demonstrates how to compare documents and protect resultant document with password.

using (Comparer comparer = new Comparer("source.docx"))
{
	comparer.Add("target.docx");
    CompareOptions cOptions = new CompareOptions
    {
     	PasswordSaveOption = PasswordSaveOption.User
    };
    SaveOptions sOptions = new SaveOptions()
    {
     	Password = "3333"
    };
    comparer.Compare("result.docx", sOptions, cOptions);
}
