Return an error when invalid parameters are specified in ASP Web API

Question

I\'m creating an API using C# and ASP.NET Web API and I want it to return an error when a parameter is used that isn\'t recognised.

For example:

/api/Eve         


        

Answer 1

try strongly typed actions like this

  public string Get()
        {
            return "I'm alive empty";
        }

  public string Get([FromUri] int id)
        {
            return "I'm alive";
        }

So normal call will return I'm alive or I'm alive empty

  http://localhost:1578/api/alive?id=1 //OR
  http://localhost:1578/api/alive

But if you try to call it like this

http://localhost:1578/api/alive?blablabla=1

You will occure this error The requested resource does not support http method 'GET'.
