基础工程
注入FreeSqlDataService服务,支持全数据导出
更新包
<PackageReference Include="BootstrapBlazor" Version="7.2.3-beta03" />
<PackageReference Include="Densen.FreeSql.Extensions.BootstrapBlazor" Version="7.*" />
Program.cs 添加代码
using Densen.DataAcces.FreeSql;
builder.Services.AddSingleton(typeof(FreeSqlDataService<>));
builder.Services.ConfigureJsonLocalizationOptions(op =>
{
// 忽略文化信息丢失日志
op.IgnoreLocalizerMissing = true;
});
Index.razor添加一个 TabItem
Tab 顺便改为懒加载
<Tab IsLazyLoadTabItem="true">
...
<TabItem Text="综合演示">
<ImpExpIII />
</TabItem>
</Tab>
添加打印预览 Pages\_Host.cshtml
< / body > 前加一句
<script>
function printDiv() {
window.print();
}
</script>
数据实体类 Data\SalesChannels.cs
