現在のプロジェクトの契約生成ルーチンを開始したばかりで、要件の 1 つは、契約の各行に番号を付ける必要があることです。番号は、ドキュメントの残りの部分から番号付けを分離する垂直方向の罫線を使用して、左マージンに配置する必要があります。
FixedDocument を使用してこの要件に取り組むことができると確信していますが、楽しいものではありません。代わりに FlowDocument でこれを行うことができますか?

以下に掲載されている私のWpfPrintヘルパークラスを使用すると、FixedDocumentを使用してこれを非常に簡単に行うことができます。XPSの作成に使用するには、XPSのコンストラクターを使用します。
WpfPrint printer = new WpfPrint(new Size(1024, 768));
printer.CurrentElementMargin = new Thickness(2, 2, 2, 2);
printer.CurrentFontFamily = new FontFamily("Arial");
printer.CurrentFontSize = BaseFontSize;
printer.MarginX = 24;
printer.MarginY = 24;
これで、ループして必要なものを追加できます。TextBlocksは、おそらくあなたが探していたものでしょう：
printer.AddTextBlock("Basics", printer.PageSizeUsed.Width, 0, WpfPrint.ElementFlags.NewLine | WpfPrint.ElementFlags.BottomCheck2);
ラップして作成すると、ラップされます。追加された各アイテムが測定されます。ページに収まらない場合、ヘルパークラスは新しいページを追加し、それを新しいページにフローします。そのため、FlowDocumentから必要なものを取得できます。CurXとCurYはいつでも変更して、アイテムを配置するときに水平方向または垂直方向のスペースをスキップできます。完了したら、次のようにプリンタに印刷できます。
// Print final document
XpsDocumentWriter xpsDocumentWriter = PrintQueue.CreateXpsDocumentWriter(dlg.PrintQueue);
xpsDocumentWriter.Write(printer.CurrentFixedDocument);
または、XPSファイルとして保存することもできます。
using (XpsDocument doc = new XpsDocument(filename, FileAccess.Write))
{
XpsDocumentWriter xpsDocumentWriter = XpsDocument.CreateXpsDocumentWriter(doc);
xpsDocumentWriter.Write(printer.CurrentFixedDocument);
}
これがヘルパークラスです。楽しみ！FlowDocumentを二度と使いたくないでしょう:-)
