Route without lambda expression

Question

Below is the official example for registering routes in Nancy. But what if I do not want to "do something" in that method, but do it in DoSomething(), instead?

public class ProductsModule : NancyModule
{
    public ProductsModule()
    {
        Get["/products/{id}"] = _ =>
        {
            //do something
        };
    }
}

public abstract class NancyModule : INancyModule, IHideObjectMembers
{
    public RouteBuilder Get { get; }
}

public class RouteBuilder : IHideObjectMembers
{
    public RouteBuilder(string method, NancyModule parentModule);
    public Func<dynamic, dynamic> this[string path] { set; }
}

I do not know what signature DoSomething should have. Can this work something like below? It is not that I must not use lambda expression; I am just curious because all these patterns Nancy is using look quite bizarre and unique.

public class ProductsModule : NancyModule
{
    ???? DoSomething(????)
    {
        //do something
        return ????
    }

    public ProductsModule()
    {
        Get["/products/{id}"] = DoSomething;
    }
}

From the Nancy documentation:

A route Action is the behavior which is invoked when a request is matched to a route. It is represented by a lambda expression of type Func<dynamic, dynamic> where the dynamic input is a DynamicDictionary, a special dynamic type that is defined in Nancy and is covered in Taking a look at the DynamicDictionary.

So, you can simply do the following:

Get["/products/{id}"] = DoSomething;

Where DoSomething is defined as:

private dynamic DoSomething(dynamic parameters)
