为 Audit.Net 创建一个独立的 ServiceProvider 并将其与 ASP.NET Core DI 集成。下面是代码示例：

public static class AuditNetExtensions
{
    public static IServiceCollection AddAudit(this IServiceCollection services, 
    Action configure = null)
    {
        var auditCfg = new AuditConfiguration();
        configure?.Invoke(auditCfg);
        Audit.Core.Configuration.Setup()
            .UseDynamicProvider(provider => provider.Configure(auditCfg))
            .WithCreationPolicy(EventCreationPolicy.InsertOnStartReplaceOnEnd)
            .ResetActions();
            
        services.AddSingleton(_ => auditCfg);
        services.AddSingleton();
        services.AddSingleton();
        services.AddSingleton();
        services.AddSingleton();
        services.AddSingleton();
        services.AddSingleton();
        services.AddSingleton();
        services.AddSingleton();
        services.AddTransient();
        services.AddTransient();
        services.AddTransient();
        services.AddTransient();
        services.AddTransient();
        services.AddTransient();
        services.AddTransient();
        services.AddTransient();
        services.AddTransient();
        services.AddTransient();
        services.AddScoped();
        services.AddScoped();
        services.AddScoped();
        
        return services;
    }

    public static IApplicationBuilder UseAudit(this IApplicationBuilder app)
    {
        app.UseMiddleware();
        return app;
    }
}

在 Startup.cs 中使用如下代码调用：

services.AddAudit(config => config
    .UseSqlServer(_configuration["ConnectionString"])
    .WithCreationPolicy(EventCreationPolicy.InsertOnEnd)
    .LogTo(_logger.LogAuditEvent));

这将为 Audit.Net 创建一个单独的 ServiceProvider 并将其与 ASP.NET Core DI 集成。
