使用DI指定ILogger<T>类型而不是Logger，其中T是使用记录器的类类型，因此NLog会知道该类.例如:

Using DI specify ILogger<T> type instead of Logger, where T is the class type that uses the logger, so NLog will know about the class. For example:

public class TodoController : Controller
{
    private readonly ILogger _logger;

    public TodoController(ILogger<TodoController> logger)
    {
        _logger = logger;
    }
}
