在asp net core中扩展IServiceCollection

using Microsoft.Extensions.DependencyInjection;

public static class MyServiceCollectionExtensions
{
    public static IServiceCollection AddMyService(this IServiceCollection services)
    {
        services.AddTransient<IMyService, MyService>(); // 注册自定义服务
        
        return services;
    }
}

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.DependencyInjection;

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMyService(); // 使用自定义扩展方法注册服务
        
        // 其他服务配置
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        // 应用程序配置
    }
}
