本文介绍了一个自定义打印对话框类，该类允许用户指定要打印的页面范围，而不是默认打印所有页面。通过创建XPS文档并逐页写入指定范围内的页面来实现。

坑爹的PrintDialog 其实并没有队PageRange这个属性做处理。自己处理一下~

public class PrintDialogWithPageRange:PrintDialog
    {
        public new void PrintDocument(DocumentPaginator doc, string desp)
        {
            if (this.PageRangeSelection == PageRangeSelection.AllPages)
            {
                base.PrintDocument(doc,desp);
            }
            else
            {
                string timeStamp = DateTime.Now.DayOfYear.ToString() + DateTime.Now.Hour + DateTime.Now.Minute + DateTime.Now.Second;
                string pack = "pack://temp" + timeStamp + ".xps";
                var ms = new MemoryStream();
                var package = Package.Open(ms, FileMode.Create, FileAccess.ReadWrite);
                PackageStore.AddPackage(new Uri(pack), package);
                var xpsDoc = new XpsDocument(package, CompressionOption.SuperFast, pack);
                var xpsDocumentWriter = XpsDocument.CreateXpsDocumentWriter(xpsDoc);
                xpsDocumentWriter.Write(doc);
                var fdsCopy = xpsDoc.GetFixedDocumentSequence();

                var xdw =System.Printing.PrintQueue.CreateXpsDocumentWriter(this.PrintQueue);
                var vtxd = (VisualsToXpsDocument)xdw.CreateVisualsCollator();
                for (int i = this.PageRange.PageFrom - 1; i < this.PageRange.PageTo; i++)
                {
                    var v = fdsCopy.DocumentPaginator.GetPage(i).Visual;
                    var cv = new ContainerVisual();
                    cv.Children.Add(v);
                    vtxd.Write(cv, this.PrintTicket);
                    cv.Children.Remove(v);
                }
                vtxd.EndBatchWrite();
                xpsDoc.Close();
                ms.Close();
                ms.Dispose();
            }
        }

}
