Actions and QueryString parameters in Web API

Question

I want to have my generic route determine if a query string was passed in the Url like this

http://localhost/query/DailyLogs/1?dateOfLog='1/13/2013'

Here is my current Route definition:

routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "query/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional}
        );

I have read some answers that say to add the dateOfLog value as an optional action on the Route defintion:

routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "query/{controller}/{id}/{dateOfLog}",
            defaults: new { id = RouteParameter.Optional, 
            dateOfLog = RouteParameter.Optional }
        );

This does not seem to work, maybe I am doing something wrong, I am not sure.

This is how I am currently handling the problem, but I would like to use the ModelBinding power of the Routing Engine:

 var queryValue = Request.RequestUri.ParseQueryString();
 string dateOfLog = queryValue["dateOfLog"];

Please tell me how to create a Route definition that will use ModelBinding correctly and map my custom url to the controller's parameters.

In the controller action, just include DateTime dateOfLog as a method parameter and continue to use the query string as it will get mapped just fine, Web API will use the correct method overload if it finds it.

I have tried that, with no success. Here is the method signature: public DailyLogResponse Get(int id, DateTime dateOfLog), using the route above this never hits the method.

Ok, try using a string type rather than DateTime in the method parameter.

Yes, you are correct it is actually a DateTime parsing error, when I changed the parameter type to string the method fires and the values are present. Thanks.

That is probably b/c your query-string parameter includes single-quotes, which is unnecessary in a URL. Also, your forward slash date-part separates should be URL encoded
