根据Word模板导出word文档，包含文本标签替换为图片，生成列表数据，以及标签替换等功能

一、前言

最近项目开发中，有一个根据word模板和指定的数据导出word文件的需求，word模板文件如下，需要将指定标签替换为数据中指定的字段，表格根据第一行的标签生成列表数据，将指定的标签替换为图片，word模板如下

二、开发准备，为了做成一个通用的word导出功能，只需要提供模板以及数据实体就可以实现导出不一样的数据，项目中主要使用以下Nuget包

　　1、DocumentFormat.OpenXml  用于word文件修改编辑操作

　　2、BarcodeLib 用于生成条码图片

　　3、SkiaSharp 用于生成跨平台的图片格式

三、word模板文件编辑，word模板文件图片如下，请注意：标签中不要换行加tab符等，否则读取模板文件时标签一个标签可能会变成多个标签

四、word生成帮助类，该类主要功能，根据指定的数据和模板生成word文件并且直接下载，如果需要保存可以指定保存路径，代码如下：　　

using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Drawing;
using DocumentFormat.OpenXml.Drawing.Wordprocessing;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Wordprocessing;
using System.Reflection;
using Run = DocumentFormat.OpenXml.Wordprocessing.Run;
using Table = DocumentFormat.OpenXml.Wordprocessing.Table;
using TableCell = DocumentFormat.OpenXml.Wordprocessing.TableCell;
using TableGrid = DocumentFormat.OpenXml.Wordprocessing.TableGrid;
using TableProperties = DocumentFormat.OpenXml.Wordprocessing.TableProperties;
using TableRow = DocumentFormat.OpenXml.Wordprocessing.TableRow;
using Text = DocumentFormat.OpenXml.Wordprocessing.Text;

由于WordHelper中使用的实体类是动态的，替换的标签也在是实体类中根据特性指定的，特性类中指定标签名称、是否图片、图片宽度、图片高度等参数，替换模板数据时会根据实体类反射解析实体中的特性来替换数据内容，特性类代码如下：

 1 namespace Core.Attributes
 2 {
 3     [AttributeUsage(AttributeTargets.Field | AttributeTargets.Property, Inherited = true, AllowMultiple = false)]
 4     public class ExportTemplateAttribute : Attribute
 5     {
 6         public ExportTemplateAttribute(string templateName, bool isImage = false, double imageWidth = 0, double imageHeight = 0)
 7         {
 8             TemplateName = templateName;
 9             IsImage = isImage;
10             ImageWidth = imageWidth;
11             ImageHeight = imageHeight;
12         }
13         /// <summary>
14         /// 是否图片属性
15         /// </summary>
16         public bool IsImage { get; set; } = false;
17         /// <summary>
18         /// 图片宽度（单位：cm）
19         /// </summary>
20         public double ImageWidth { get; set; } = 0;
21         /// <summary>
22         /// 图片高度（单位：cm）
23         /// </summary>
24         public double ImageHeight { get; set; } = 0;
25         /// 模板名称
26         /// </summary>
27         public string TemplateName { get; set; } = string.Empty;
28     }
29
30 }

五、条形码生成类，根据指定内容、尺寸生成条码，代码如下：

using BarcodeStandard;
using SkiaSharp;

public class BarcodeUtils
{

    public static MemoryStream GenerateBarcode(string text, BarcodeStandard.Type type, int width = 320, int height = 80)
    {
        var barcode = new Barcode
        {
            IncludeLabel = false,
            Alignment = BarcodeStandard.AlignmentPositions.Center,
            Width = width,
            Height = height,
            EncodedType = type,
            BackColor = SKColors.White,
            ForeColor = SKColors.Black,

        };

        var image = barcode.Encode(type, text);
        // 创建内存流
        var encodedData = image.Encode(SKEncodedImageFormat.Png, 100);
        var stream = new MemoryStream();

        encodedData.SaveTo(stream);
        stream.Position = 0; // 重置流位置以便读取
        return stream;
    }
}

六、实体数据类，数据类中需要指定标签、以及是否图片替换等属性，示例代码如下

    using Core.Attributes;

    /// <summary>
    /// 导出模板
    /// </summary>
    public class DateTemplate
    {

        /// <summary>
        /// 名称
        /// </summary>
        [ExportTemplate("name", false, 0, 0)]
        public string Name { get; set; }
        /// <summary>
        /// 编号
        /// </summary>
        [ExportTemplate("number", false, 0, 0)]
        public string Number { get; set; }

        /// <summary>
        /// 采样时间
        /// </summary>
        [ExportTemplate("specimenTime")]
        public DateTime CreateTime { get; set; }

列表的实体数据类和标签数据类是一样的，此处不再举例

七、生成文件，示例代码如下：

1 //其中DataTemplate是标签数据类，ListItem1是列表1的实体类型，ListItem2 是列表2的实体类型 1和2 表示表格的索引值
2 var outdata = WordHelper.GenerateDocumentFromTemplate<DataTempalte, ListItem1, ListItem2>(templatePath, exportdata, resultItems, 1, resultITems1, 2);

八、文件导出，示例代码如下：

/// <summary>
/// 导出模板
/// </summary>
/// <param name="input"></param>
/// <returns></returns>
[HttpPost("ExportResult")]
[Description("导出结果")]
public async Task<dynamic> ExportResult([FromBody] inputdata input)
{
   var fileName="wordfile.docx";
   /// 根据Id获取数据
    var exportdata= serivce.getData(input.id)
    var outdata = WordHelper.GenerateDocumentFromTemplate<DataTempalte, ListItem1, ListItem2>(templatePath, exportdata, exportdata.list1, 1, exportdata.list2, 2);
///返回文件流
 return  new FileStreamResult(new MemoryStream(byteArray), "application/octet-stream") { FileDownloadName = fileName };
}

以上就是所有的代码，感谢deepseek提供的解决方案，已调试通过，在开发过程中，遇到了以下问题

1、通过模板无法找到Text元素和Table元素，尝试了很多方法都没有解决，最后找到了原因，竟然是由于Text和Table引用的命名空间不正确，我们需要使用的命名空间是DocumentFormat.OpenXml.Wordprocessing，但是我在项目中使用的是DocumentFormat.OpenXml.Drawing，代码编译不会报错，就是找不到指定元素

2、插入图片元素不显示，推测原因，是因为标签中包含了其它元素，删除即可
