.net ofd文件转pdf

您可以使用iTextSharp库将OFD文件转换为PDF。以下是使用C#代码实现的示例：

using iTextSharp.text;
using iTextSharp.text.pdf;
using System.IO;

public void ConvertOFDToPDF(string inputFilePath, string outputFilePath)
{
    // Load the OFD file
    iTextSharp.text.pdf.codec.OFDParse ofd = new iTextSharp.text.pdf.codec.OFDParse(inputFilePath);
    if (ofd == null)
    {
        throw new IOException("Cannot open input file: " + inputFilePath);
    }

    // Create a new PDF document
    Document document = new Document();
    PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(outputFilePath, FileMode.Create));
    document.Open();

    // Read each page of the OFD file and add it to the PDF document
    for (int i = 1; i <= ofd.GetNumberOfPages(); i++)
    {
        iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(ofd.GetPageBytes(i));
        document.Add(image);
    }

    // Close the document
    document.Close();
}

您需要将iTextSharp库添加到您的项目中以使用上述代码。
