Я пытаюсь создать PDF-документ из C # WPF control.Вот мой .
В результате получается половина моего объекта, как автоматически разбить страницу на страницы?
Ниже мой код:
System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => fixedDoc = new FixedDocument()));
System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => fixedDoc1 = new FixedDocument()));
System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => pageContent = new PageContent()));
System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => pageContent1 = new PageContent()));
System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => fixedPage = new FixedPage()));
System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => fixedPage1 = new FixedPage()));
var visual = Child as UIElement;
System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => (Content).Children.Remove(visual)));
System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => fixedPage.Children.Clear()));
System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => fixedPage.Children.Add(visual)));
System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => ((System.Windows.Markup.IAddChild)pageContent).AddChild(fixedPage)));
System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => fixedDoc.Pages.Add(pageContent)));
// write to PDF file
string tempFilename = "temp.Xps";
File.Delete(tempFilename);
XpsDocument xpsd = new XpsDocument(tempFilename, FileAccess.ReadWrite);
XpsDocumentWriter xw = XpsDocument.CreateXpsDocumentWriter(xpsd);
System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => xw.Write(fixedDoc)));
System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => xpsd.Close()));
filename = filepath + DateTime.Now.ToString("yyyyMMddHHmmss") + "-" + title_ + ".pdf";
PdfSharp.Xps.XpsConverter.Convert(tempFilename, filename, 1);
var visual2 = Child2 as UIElement;
Application.Current.Dispatcher.Invoke(new Action(() => (Content).Children.Remove(visual2)));
Application.Current.Dispatcher.Invoke(new Action(() => fixedPage1.Children.Clear()));
Application.Current.Dispatcher.Invoke(new Action(() => fixedPage1.Children.Add(visual2)));
Application.Current.Dispatcher.Invoke(new Action(() => ((System.Windows.Markup.IAddChild)pageContent1).AddChild(fixedPage1)));
Application.Current.Dispatcher.Invoke(new Action(() => fixedDoc1.Pages.Add(pageContent1)));
// write to PDF file
string tempFilename2 = "temp2.Xps";
File.Delete(tempFilename2);
XpsDocument xpsd2 = new XpsDocument(tempFilename2, FileAccess.ReadWrite);
XpsDocumentWriter xw2 = XpsDocument.CreateXpsDocumentWriter(xpsd2);
Application.Current.Dispatcher.Invoke(new Action(() => xw2.Write(fixedDoc1)));
Application.Current.Dispatcher.Invoke(new Action(() => xpsd2.Close()));
filename2 = filepath + DateTime.Now.ToString("yyyyMMddHHmmss") + "-" + title_ + ".pdf";
PdfSharp.Xps.XpsConverter.Convert(tempFilename2, filename2, 1);
