您将如何以编程方式在SWF中嵌入SWF？

代码可能如下所示：

// create an output file stream which will be used to capture the generated file 
    string outputFileName = "output.pdf"; 
    FileStream outputFile = new FileStream(outputFileName,FileMode.Create); 

    // open the original pdf file as a PdfReader 
    PdfReader reader = new PdfReader("inputfile.pdf"); 

    // open the output pdf file as a PdfStamper 
    PdfStamper stamper = new PdfStamper(reader,outputFile); 

    // inserts a blank page at the start of the document 
    stamper.InsertPage(1,PageSize.A4); 

    // add the flash file to the output document as an annotation 
    PdfFileSpecification fs = PdfFileSpecification.FileEmbedded(stamper.Writer,flashFileTextBox.Text,null); 
    PdfAnnotation flashInsert = PdfAnnotation.CreateScreen(stamper.Writer,new Rectangle(50f,791f,545f,420f),"Flash Insert",fs,"application/x-shockwave-flash",true); 

    stamper.AddAnnotation(flashInsert,1); 

    stamper.Close(); 
    reader.Close();
