C# word 操作进阶-01-模板环境

首先，你的计算机上必须安装 Microsoft Office Excel 2007 和 Microsoft Office Word 2007 或更高版本。

我这里项目直接com引用了office，大家可根据情况引用。

引用组件后，就可以新建word帮助类了(WordHelper.cs)

using Microsoft.Office.Interop.Word;
using System;
using System.Collections.Generic;
using System.Data;
using System.IO;
using System.Linq;
using System.Text;
using DataTable = System.Data.DataTable;
using word = Microsoft.Office.Interop.Word;

namespace Hsware.Util
{
    /// <summary>

    public class WordHelper
    {
        #region 基础区
        private object tempfile = null;//模板绝对地址
        private object savefile = null;//保存文件绝对地址
        private static Document wdoc = null; //word文档
        private static Application wapp = null; //word进程
        private object missing = System.Reflection.Missing.Value;

        /// <summary>

        public WordHelper(string tempfile, string savefile)
        {
            this.tempfile = @tempfile;
            this.savefile = @savefile;
        }

        /// <summary>

        /// <returns></returns>
        private TData Init()
        {
            TData<string> obj = new TData<string>();
            if (!File.Exists(tempfile.ToString()))
            {
                obj.Message = $"{tempfile}模板文件不存在，请先设置模板文件。";
                return obj;
            }
            wapp = new Application();
            wapp.Visible = false;
            wdoc = wapp.Documents.Add(ref tempfile, ref missing, ref missing, ref missing);
            wdoc.Activate();// 当前文档置前
            obj.Tag = 1;
            return obj;
        }

        /// <summary>

        private bool ReplaceTableRang(word.Table table, Dictionary<string, string> dc)
        {
            try
            {
                object replacearea = word.WdReplace.wdReplaceAll;

                foreach (string item in dc.Keys)
                {

                    object replacevalue = dc[item];
                    table.Range.Find.Execute(ref replacekey, ref missing, ref missing, ref missing,
                     ref missing, ref missing, ref missing, ref missing, ref missing,
                     ref replacevalue, ref replacearea, ref missing, ref missing, ref missing,
                     ref missing);
                }
                return true;
            }
            catch (Exception ex)
            {
                DisposeWord();
                //messagebox.show(string.format("{0}模板中没有找到指定的要替换的表达式。{1}", tempfile, ex.message));
                return false;
            }
        }

        /// <summary>

        private TData ReplaceAllRang(Dictionary<string, string> dc)
        {
            TData<string> obj = new TData<string>();
            try
            {
                object replacearea = word.WdReplace.wdReplaceAll;

                foreach (string item in dc.Keys)
                {
                    object replacekey = item;
                    object replacevalue = dc[item];
                    wapp.Selection.Find.Execute(ref replacekey, ref missing, ref missing, ref missing,
                     ref missing, ref missing, ref missing, ref missing, ref missing,
                     ref replacevalue, ref replacearea, ref missing, ref missing, ref missing,
                     ref missing);
                }
                obj.Tag = 1;
            }
            catch (Exception ex)
            {
                obj.Message = $"{tempfile}模板中没有找到指定的要替换的表达式。{ex.Message}";
            }
            return obj;
        }

        private void DisposeWord()
        {
            object saveoption = word.WdSaveOptions.wdSaveChanges;

            wdoc.Close(ref saveoption, ref missing, ref missing);

            saveoption = word.WdSaveOptions.wdDoNotSaveChanges;

            wapp.Quit(ref saveoption, ref missing, ref missing); //关闭word进程
        }
        #endregion

    }
}

 其中TData类仅仅是消息类，可自定义返回值或者类，个人习惯，不过我喜欢带消息的操作结果，不喜欢bool。

    /// <summary>
    /// 数据传输对象
    /// </summary>
    public class TData
    {
        /// <summary>
        /// 操作结果，Tag为1代表成功，(默认值)0代表失败，其他的验证返回结果，可根据需要设置
        /// </summary>
        public int Tag { get; set; } = 0;

        /// <summary>
        /// 提示信息或异常信息
        /// </summary>
        public string Message { get; set; }

        /// <summary>
        /// 扩展Message
        /// </summary>
        public string Description { get; set; }
    }

 到了这一步，要先保证代码没有错误。
