.NET控制台获取依赖注入实例

internal class Program
{
    static void Main(string[] args)
    {
        // 创建服务集合
        var services = new ServiceCollection();
        // 注入
        services.AddScoped<IMyService, MyService>();
        // 配置服务
        ConfigureServices(services);
        // 创建服务提供者
        var serviceProvider = services.BuildServiceProvider();
        // 获取DbContext实例
        using (var db = serviceProvider.GetRequiredService<YouDbContext>())
        {
            var data = db.Database.SqlQuery<TableModel>($"select * from Table").ToList();
        }

        //or 获取服务实例
        var services = serviceProvider.GetService<IMyService>();
        services.Execute();

    }

    private static void ConfigureServices(IServiceCollection services)
    {
        services.AddDbContext<CfwDbContext>(options =>
            options.UseSqlServer("你的数据库链接"));
    }
