C #을 통해 OST를 XPS로 변환

using (var ost = PersonalStorage.FromFile("storage.ost"))
{
    // Ensure the output directory exists
    Directory.CreateDirectory(outputDirectory);

    var inboxFolder = ost.GetPredefinedFolder(StandardIpmFolder.Inbox);

    // Iterate through mbox messages and save them as .xps files
    int count = 1;

    foreach (var msg in inboxFolder.EnumerateMapiMessages())
    {
        // Instantiate an instance of MailPrinter
        var printer = new Printing.MailPrinter();

        // Set MessageFormattingFlags to MailInfo to display the message headers and body
        printer.FormattingFlags = Printing.MessageFormattingFlags.MailInfo;

        // Set page layout for printing
        printer.PageUnit = Printing.PrinterUnit.Cm;
       
        var dstXPS = Path.Combine(outputDirectory, $"Message{count}.xps");
       
        // Print the email to an XPS file
        printer.Print(msg, dstXPS, Printing.PrintFormat.XPS);
