I followed this.

我跟着这个。

1. download the zips and add dll in your project.

2. use following code

     MemoryStream lMemoryStream = new MemoryStream();
     Package package = Package.Open(lMemoryStream, FileMode.Create);
     XpsDocument doc = new XpsDocument(package);
     XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter(doc);
     writer.Write(dp);
     doc.Close();
     package.Close();
   
     var pdfXpsDoc = PdfSharp.Xps.XpsModel.XpsDocument.Open(lMemoryStream);
     PdfSharp.Xps.XpsConverter.Convert(pdfXpsDoc, FileName, 0);
   

   where dp should be your wpf control.

1. 下载 zips 并在您的项目中添加 dll。

2. 使用以下代码

     MemoryStream lMemoryStream = new MemoryStream();
     Package package = Package.Open(lMemoryStream, FileMode.Create);
     XpsDocument doc = new XpsDocument(package);
     XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter(doc);
     writer.Write(dp);
     doc.Close();
     package.Close();
   
     var pdfXpsDoc = PdfSharp.Xps.XpsModel.XpsDocument.Open(lMemoryStream);
     PdfSharp.Xps.XpsConverter.Convert(pdfXpsDoc, FileName, 0);
   

   其中 dp 应该是您的 wpf 控件。

THEN

然后

     PdfSharp.Xps.XpsConverter.Convert(sourceXpsFile, destPdfFile, 0);

DONE :)

完毕 ：）
