我要评论前提
安装office 2019
安装vs 2022
新建项目
引入4个com包
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()
{

microsoft.office.interop.excel.workbook workbook = null;
