C＃。文档到 PDF 的转换

Question

我正在尝试使用 Visual Studio 2013 将 doc 或 docx 文件转换为 PDF。C# 语言。 我尝试调试，但我认为以下部分代码有问题：

public static void Main(string[] args)
    {
        if (args.Count() > 1)
        {
            translate.ConvertAllWordFilesToPdf(args[0], args[1]);
        }

    }

我没有收到任何错误。我得到这个输出消息： 程序“[9240] Conversion.vshost.exe”已退出，代码为 0 (0x0)。

感谢您的帮助。

Answer 1

我注意到一段非常有趣的代码：

sourceFile = WordFilesLocation + @"C:\Source" + destinationFile;
destinationFile = PdfFilesLocation + @"C:\Destination" + destinationFile;

尝试删除@"C:\Source"。 我删除了它，代码在我的电脑上运行了。

另外，我不确定您是否应该为某些位置字符串附加@"\"（不以“\”结尾）。小心点。
