如何通过依赖注入使用IMediator (MediatR)在带有AutoFac的Umbro7控制器中？

public class Umbro7Controller : Controller
{
    private readonly IMediator _mediator;

    public Umbro7Controller(IMediator mediator)
    {
        _mediator = mediator;
    }

    // Other dependencies can be injected here

    // Controller actions
}

var builder = new ContainerBuilder();

// Register IMediator
builder.Register<IMediator>(c => new Mediator(c.Resolve));

// Register other dependencies
// ...

// Build the container
var container = builder.Build();

// Set the dependency resolver
DependencyResolver.SetResolver(new AutofacDependencyResolver(container));

public async Task<IActionResult> SomeAction()
{
    var result = await _mediator.Send(new SomeRequest());

    // Process the result and return the appropriate response
}
