声明构造函数时无法运行基准测试

Question

我是基准测试的新手，我正在尝试对我的控制器端点进行基准测试，但是我得到了一个错误BenchmarkDotNet has failed to build the auto-generated boilerplate code.，当我在没有类构造函数的情况下运行一些测试时，一切都运行顺利…我一定是做错了什么…

(我已经为依赖注入创建了一个启动类)

benchmark类

[MemoryDiagnoser]
public class UserController
{
private readonly UsersController _controller;
// when I comment this out everything runs smoothly...
/*public UserController(ApplicationDbContext context, IWebHostEnvironment hostingEnvironment) 
{
_controller = new UsersController(context, hostingEnvironment);
}*/
[Benchmark]
public async Task LoginUserErrorAsync()
{
var test = ("kibkjbc").Substring(2);
// await _controller.LoginUserAsync();
}
}

项目类

internal class Program
{
static void Main(string[] args)
{
var config = new ManualConfig()
.WithOptions(ConfigOptions.DisableOptimizationsValidator)
.AddValidator(JitOptimizationsValidator.DontFailOnError)
.AddLogger(ConsoleLogger.Default)
.AddColumnProvider(DefaultColumnProviders.Instance);
BenchmarkRunner.Run<UserController>(config);
}
}

BenchmarkDotNet需要一个默认构造函数来实例化类。关于如何使用DI设置基准测试，请查看以下内容。
