示例
描述依赖关系的首选方法是使用构造函数注入，它遵循显式依赖性原则：
ITestService.cs
public interface ITestService
{
int GenerateRandom();
}TestService.cs
public class TestService : ITestService
{
public int GenerateRandom()
{
return 4;
}
}Startup.cs(ConfigureServices)
public void ConfigureServices(IServiceCollection services)
{
// ...
services.AddTransient<ITestService, TestService>();
}HomeController.cs
using Microsoft.Extensions.DependencyInjection;
namespace Core.Controllers
{
public class HomeController : Controller
{
public HomeController(ITestService service)
{
int rnd = service.GenerateRandom();
}
}
}
