编写代码

代码结构

代码如下

using Microsoft.Office.Interop.Excel;namespace UseMsOffice
{internal class Program{static void Main(string[] args){WordToPdf();ExcelToPdf();PPTToPdf();}static void WordToPdf(){// Word应用程序对象  var wordApp = new Microsoft.Office.Interop.Word.Application();Microsoft.Office.Interop.Word.Document? doc = null;string root = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase ?? "";try{// 设置为不可见模式  wordApp.Visible = false;var docPath = Path.Combine(root, "Document", "office.docx");// 打开一个现有的Word文档  doc = wordApp.Documents.Open(docPath);// 将文档另存为PDF  string pdfPath = Path.Combine(root, $"{DateTime.Now.ToString("yyyy_MM_dd_HH_mm_ss")}_office.pdf");doc.ExportAsFixedFormat(pdfPath, Microsoft.Office.Interop.Word.WdExportFormat.wdExportFormatPDF);// 关闭文档和Word应用  doc.Close();wordApp.Quit();Console.WriteLine("文档已成功转换为PDF格式。");}catch (Exception ex){Console.WriteLine("发生错误：" + ex.Message);}finally{// 释放COM对象  System.Runtime.InteropServices.Marshal.ReleaseComObject(doc);System.Runtime.InteropServices.Marshal.ReleaseComObject(wordApp);doc = null;wordApp = null;}}static void ExcelToPdf(){// Excel应用程序对象  var excelApp = new Microsoft.Office.Interop.Excel.Application();Microsoft.Office.Interop.Excel.Workbook workBook = null;string root = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase ??
