10分钟做好 Bootstrap Blazor 的表格组件导出 Excel/Word/Html/Pdf
上篇: Bootstrap Blazor 实战 通用导入导出服务(Table组件)
1.新建工程
新建工程b14table
dotnet new blazorserver -o b14table
将项目添加到解决方案中：
dotnet sln add b14table/b14table.csproj
使用 nuget.org 进行 BootstrapBlazor 组件安装, FreeSql sqlite库,字体 ..
dotnet add b03sqlite package BootstrapBlazor
dotnet add b03sqlite package BootstrapBlazor.FontAwesome
dotnet add b03sqlite package FreeSql.Provider.Sqlite
dotnet add b03sqlite Densen.Extensions.BootstrapBlazor
dotnet add b03sqlite package Densen.FreeSql.Extensions.BootstrapBlazor
dotnet add b03sqlite package Magicodes.IE.Core
dotnet add b03sqlite package Magicodes.IE.Excel
dotnet add b03sqlite package Magicodes.IE.Html
dotnet add b03sqlite package Magicodes.IE.Pdf
dotnet add b03sqlite package Magicodes.IE.Word
dotnet add b03sqlite package HtmlToOpenXml.dll
dotnet add b03sqlite package Haukcode.WkHtmlToPdfDotNet
[可选]BootstrapBlazor官方BootstrapBlazor.DataAcces.FreeSql包替换Densen.FreeSql.Extensions.BootstrapBlazor
2.样式表和Javascript 引用
增加主题样式表到 Pages/_Host.cshtml 文件中
删除 <link rel="stylesheet" href="css/bootstrap/bootstrap.min.css" />
并在下面添加两行
<link href="_content/BootstrapBlazor.FontAwesome/css/font-awesome.min.css" rel="stylesheet">
<link href="_content/BootstrapBlazor/css/bootstrap.blazor.bundle.min.css" rel="stylesheet">
添加 Javascript 引用到 Pages/_Layout.cshtml 文件中
在 <script src="_framework/blazor.server.js"></script> 之前添加
<script src="_content/BootstrapBlazor/js/bootstrap.blazor.bundle.min.js" asp-append-version="true"></script>
完整文件
@page "/"
@using Microsoft.AspNetCore.Components.Web
@namespace b14table.Pages
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<base href="~/" />
<!-- 删掉这行 <link rel="stylesheet" href="css/bootstrap/bootstrap.min.css" /> !-->
<link href="css/site.css" rel="stylesheet" />
<!-- 添加下面两行 !-->
<link href="_content/BootstrapBlazor.FontAwesome/css/font-awesome.min.css" rel="stylesheet">
<link href="_content/BootstrapBlazor/css/bootstrap.blazor.bundle.min.css" rel="stylesheet">
<!-- 添加上面两行 !-->
<link href="b14table.styles.css" rel="stylesheet" />
<link rel="icon" type="image/png" href="favicon.png" />
<component type="typeof(HeadOutlet)" render-mode="ServerPrerendered" />
</head>
<body>
<component type="typeof(App)" render-mode="ServerPrerendered" />
<div id="blazor-error-ui">
<environment include="Staging,Production">
An error has occurred. This application may no longer respond until reloaded.
</environment>
<environment include="Development">
An unhandled exception has occurred. See browser dev tools for details.
</environment>
<a href="" class="reload">Reload</a>
<a class="dismiss"></a>
</div>
<!-- 增加这行 !-->
<script src="_content/BootstrapBlazor/js/bootstrap.blazor.bundle.min.js"></script>
<script src="_framework/blazor.server.js"></script>
</body>
</html>
3.添加增加命名空间引用到 _Imports.razor 文件中
其中 AME.Services 和 Blazor100.Service 命名空间稍后文件里用到
@using BootstrapBlazor.Components
@using AME.Services
@using Blazor100.Service
@using System.Diagnostics.CodeAnalysis
4.增加 BootstrapBlazorRoot 组件到 App.razor 文件中
<BootstrapBlazorRoot>
<Router AppAssembly="@typeof(App).Assembly">
...
</Router>
</BootstrapBlazorRoot>
5.添加 BootstrapBlazor服务/ FreeSql 数据服务/ ImportExportsService 导出服务 到 Program.cs 文件中
在 builder.Services.AddSingleton<WeatherForecastService>(); 后加入
builder.Services.AddFreeSql(option =>
{
option.UseConnectionString(FreeSql.DataType.Sqlite, "Data Source=test.db;") //也可以写到配置文件中
#if DEBUG
//开发环境:自动同步实体
.UseAutoSyncStructure(true)
.UseNoneCommandParameter(true)
//调试sql语句输出
.UseMonitorCommand(cmd => System.Console.WriteLine(cmd.CommandText))
#endif
;
});
builder.Services.AddTransient<ImportExportsService>();
//不写这句因为下面一句扩展包含了 //builder.Services.AddBootstrapBlazor();
builder.Services.AddDensenExtensions();
6. 导出服务 Service/ImportExportsService.cs
using BootstrapBlazor.Components;
using Magicodes.ExporterAndImporter.Core;
using Magicodes.ExporterAndImporter.Excel;
using Magicodes.ExporterAndImporter.Html;
using Magicodes.ExporterAndImporter.Pdf;
using Magicodes.ExporterAndImporter.Word;
namespace Blazor100.Service
{
/// <summary>
/// 通用导入导出服务类
/// </summary>
public class ImportExportsService
{
public enum ExportType
{
Excel,
Pdf,
Word,
Html
}
public async Task<string> Export<T>(string filePath, List<T>? items = null, ExportType exportType = ExportType.Excel) where T : class, new()
{
switch (exportType)
{
case ExportType.Pdf:
var exporterPdf = new PdfExporter();
items = items ?? new List<T>();
var resultPdf = await exporterPdf.ExportListByTemplate(filePath + ".pdf", items);
return resultPdf.FileName;
case ExportType.Word:
var exporterWord = new WordExporter();
items = items ?? new List<T>();
var resultWord = await exporterWord.ExportListByTemplate(filePath + ".docx", items);
return resultWord.FileName;
case ExportType.Html:
var exporterHtml = new HtmlExporter();
items = items ?? new List<T>();
var resultHtml = await exporterHtml.ExportListByTemplate(filePath + ".html", items);
return resultHtml.FileName;
default:
IExporter exporter = new ExcelExporter();
items = items ?? new List<T>();
var result = await exporter.Export(filePath + ".xlsx", items);
return result.FileName;
}
}
public async Task<(IEnumerable<T>? items,string error)> ImportFormExcel<T>(string filePath) where T : class, new()
{
IExcelImporter Importer = new ExcelImporter();
var import = await Importer.Import<T>(filePath);
if (import.Data == null )
{
return (null, import.Exception.Message);
}
return (import.Data!.ToList(),"");
}
}
}
7. 数据实体类 Data/WeatherForecast.cs
using BootstrapBlazor.Components;
using FreeSql.DataAnnotations;
using Magicodes.ExporterAndImporter.Excel;
using OfficeOpenXml.Table;
using System.ComponentModel;
namespace b14table.Data;
[ExcelImporter(IsLabelingError = true)]
[ExcelExporter(Name = "导入商品中间表", TableStyle = TableStyles.Light10, AutoFitAllColumn = true)]
[AutoGenerateClass(Searchable = true, Filterable = true, Sortable = true)]
public class WeatherForecast
{
[Column(IsIdentity = true)]
[DisplayName("序号")]
public int ID { get; set; }
[DisplayName("日期")]
public DateTime Date { get; set; }
public int TemperatureC { get; set; }
public int TemperatureF => 32 + (int)(TemperatureC / 0.5556);
public string? Summary { get; set; }
}
