使用FreeSpire.Doc不安装Office组件的情况下操作Word文件

第一步 ：添加Nuget引用 FreeSpire.Doc

第二部：添加如下代码

using Spire.Doc;
using System.Collections.Generic;
using System.IO;

namespace ConsoleApp1
{
    /// 

    /// Word文档抽象类
    /// 
    public abstract class WordProtocol
    {
        #region 属性
        /// 

        /// 协议模板路径
        /// 
        public string ProtocolPath { get; set; }
        /// 

        /// 协议保存文件名
        /// 
        public string SaveFileName { get; set; }
        /// 

        /// Word文档对象
        /// 
        public Document Doc { get; set; }

        /// 

        /// 模板字符
        /// 
        public List TemplateStrings { get; set; }
        #endregion

        /// 

        /// 协议内容替换准备
        /// 
        public virtual void Ready()
        {
            if (File.Exists(ProtocolPath) == false)
            {
                return;
            }

            Doc = new Document();
            Doc.LoadFromFile(ProtocolPath);
        }

        /// 

        /// 协议内容替换中(业务抽象方法)
        /// 
        public abstract void BizReplace();

        /// 

        /// 协议替换完成
        /// 
        public virtual void Finish()
        {
            //不允许任何更改（只读），设置解除限制编辑的密码
            Doc.Protect(ProtectionType.AllowOnlyReading, "123");
            Doc.SaveToFile(SaveFileName, FileFormat.Doc);
            Doc.Close();
        }

        /// 

        /// 模板方法
        /// 
        public void Run()
        {
            Ready();

            BizReplace();

            Finish();
        }
    }
}

using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System;
using System.Drawing;

namespace ConsoleApp1

    public class PaymentNoticeProtocol : WordProtocol
    {
        /// 

        /// 图片路径
        /// 
        public string ImagePath { get; set; }

        public PaymentNoticeProtocol(string imagePath)
        {
            this.ImagePath = imagePath;
        }

        /// 

        /// 替换内容业务
        /// 
        public override void BizReplace()
        {
            foreach (string item in TemplateStrings)
            {

                string newStr = "";
                switch (item.Trim())
                {

                        break;
                }

                TextSelection selection = Doc.FindString(item.Trim(), false, true);
                TextRange range = selection.GetAsOneRange();
                //替换的文本
                range.Text = newStr;     
            }
            AddPicture();
        }

        private void AddPicture()
        {
            //从文档的第一个段落添加
            Paragraph para = Doc.Sections[0].Paragraphs[0];

            var image = Image.FromFile(ImagePath);
            DocPicture picture = para.AppendPicture(image);

            //设置图片大小
            picture.Width = 100f;
            picture.Height =50f;

            para.AppendHyperlink("www.baidu.com", picture, HyperlinkType.WebLink);
        }
    }
}

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.IO;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            string basePath = AppDomain.CurrentDomain.BaseDirectory;
            string path = basePath + "Template\\交费通知单.doc";

            WordProtocol protocol = new PaymentNoticeProtocol(basePath + "Images\\bd_logo1.png")
            {
                ProtocolPath = path,
                SaveFileName = "demo.doc",
                TemplateStrings=new List { "[打印年]", "[打印月]", "[打印日]" }  
            };
            protocol.Run();

            OpenPreviewFile(AppDomain.CurrentDomain.BaseDirectory+protocol.SaveFileName);
        }

        /// 

        /// 默认打开替换后的文件
        /// 
        /// 
        private static void OpenPreviewFile(string path)
        {
            if (File.Exists(path) == false)
            {
                return;
            }
            Process.Start(path);
        }
    }
}

第三步： 添加一个word模板和一个图片
