C#实现将RTF文档高效转换为PDF格式的两种方法详解

Install-Package Aspose.Words

using Aspose.Words;

class Program
{
    static void Main()
    {
        // 加载 RTF 文件
        Document doc = new Document("input.rtf");

        // 保存为 PDF
        doc.Save("output.pdf", SaveFormat.Pdf);

        Console.WriteLine("RTF 已成功转换为 PDF！");
    }
}

Install-Package Microsoft.Office.Interop.Word

using Word = Microsoft.Office.Interop.Word;
using System.IO;

class RtfToPdfConverter
{
    public static void ConvertRtfToPdf(string rtfPath, string pdfPath)
    {
        var wordApp = new Word.Application();
        object missing = System.Reflection.Missing.Value;
        object inputFile = Path.GetFullPath(rtfPath);
        object outputFile = Path.GetFullPath(pdfPath);
        object fileFormat = Word.WdSaveFormat.wdFormatPDF;

        try
        {
            // 打开 RTF 文档
            Word.Document doc = wordApp.Documents.Open(
                ref inputFile, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing, ref missing);

            // 导出为 PDF
            doc.SaveAs2(ref outputFile, ref fileFormat,
                ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing);

            doc.Close();
        }
        finally
        {
            wordApp.Quit();
        }
    }
}
