c# - 使用 Pdftron 在 C# 中将 Excel 转换为 Pdf

Question

我正在尝试使用 Pdftron (Pdfnet) 库在 ASP.Net Web 应用程序中将 Excel 文档转换为 PDF。以下是我用于上述目的的代码。

    pdf.PDF.PDFDoc newSalaryFitmentPdf = new pdf.PDF.PDFDoc();
    pdftron.PDF.Convert.ToPdf(newSalaryFitmentPdf, newSalaryFitmentExcel.FullName);
salaryFitment = newSalaryFitmentPdf.Save(pdf.SDF.SDFDoc.SaveOptions.e_linearized);

但是当程序尝试执行第二行时，我得到了以下异常。

Exception: 
     Message: An error occurred while converting the file.
Detailed error:
    Error creating a new Excel application instance.
Code: PDFTRON_UNKNOWN (-2147024891)
      File: "Excel.cpp":51
    Log:

任何帮助将不胜感激。
