.Net Aspose.Words 生成Word文档

在开发WinForm项目中，有一需求要生成Word文档，百度学习，记录一下实现方法

NuGet包，找到 Aspose.Words 安装 21.8.0或以下 版本，否则高版本即使执行了注册码也会提示过期

一.新建一个基类

using Aspose.Words;
using Aspose.Words.Tables;
using System;
using System.Collections.Generic;
using System.Data;
using System.Drawing;
using System.IO;

namespace DataBrowser.Common

    public class ExportOutWord
    {
        public ExportOutWord()
        {
            //需要在启动程序中执行注册码，否则生成的Word文档会有水印。

            sfd.ShowDialog();
            string saveFilePath = sfd.FileName; //获取本地指定的存储路径

            ExportOutWord exportOutWord = new ExportOutWord();
            exportOutWord.GenerateWord(saveFilePath);
        }
