Question

I have a methoth in my web api like this:

public HttpResponseMessage Get(string path)
{
}

This is the corresponding URL:

http://server/web/api/controller?path='param'

But I want this query-string parameter optional.
I expect, if there is no query-string parameter, the string ‘path’ should be null.

But this is not working…
I have to create another method (otherwise the ‘method’ is not found)

public HttpResponseMessage Get()

Is there no other way?

Answer 1

Try providing a default value and explicitly stating it is from the Uri.

public HttpResponseMessage Get([FromUri]string path = null)
{
}
