.net core注入服务

1.在Startup的ConfigureServices里面,通过IServiceCollection进行注入

public void ConfigureServices(IServiceCollection services) { //注入服务 services.AddTransient<IEmailSender, EmailSender>(); //或者 services.Add(new ServiceDescriptor(typeof(IEmailSender), typeof(IEmailSender), ServiceLifetime.Singleton)); }

2.定义接口并实现

public interface IEmailSender { Task SendEmailAsync(string email, string subject, string message); } public class EmailSender : IEmailSender { public Task SendEmailAsync(string email, string subject, string message) { //...... } }

3.使用

public class AccountController : Controller { private readonly IEmailSender _emailSender; public AccountController(IEmailSender emailSender) { _emailSender = emailSender; } }
