How to Compare password-protected files Leave feedback

Sometimes when working with documents you may need to get the result of a comparison of files in which one or even both files are password protected, and for this very case there is an option to compare files in spite of the fact that they are protected. This option allows you to compare protected files in any format where it is possible to set a password for the file.

The code sample to compare two password-protected files:

string sourcePath = @"source.format"; // NOTE: Path to the source document
string targetPath = @"target.format"; // NOTE: Path to the target document
string resultPath = @"result.format"; // NOTE: Path to the result document

Options.LoadOptions loadOptionsSource = new Options.LoadOptions {Password = "passwordSource"}; // NOTE: options with password for the first file
Options.LoadOptions loadOptionsTarget = new Options.LoadOptions {Password = "passwordTarget"}; // NOTE: options with password for the second file

using (Comparer comparer = new Comparer(sourcePath, loadOptionsSource))
{
    comparer.Add(targetPath, loadOptionsTarget);
    CompareOptions compareOptions = new CompareOptions
   {
        DetectStyleChanges = true,
        DetalisationLevel = DetalisationLevel.High
   };
    comparer.Compare(resultPath, compareOptions);
}

As a result, we get the resulting comparison file of two password-protected files.
