Azure function v3 - bind comma separated query string value to array/list in .net

Question

Hi,
I have a use case to bind query string to a model in Azure function V3 and in that, say, one of the query string will have array values. It is a .net core function app.

For eg: <url>?item=laptop&places=Bangalore&places=Chennai&places=Mumbai

This should be bound to a model like:

public class Items{

public string item { get; set; }
public List<string> places { get; set; }

}

Tried using FromQuery which doesn't seems to be supported in Azure function.

Could you please suggest?

@sanal-kumar-p-2758 Sharing previous discussion in stackoverflow. In the same thread there is another answer if you have predefine format and does not change.

For your example you can use below code to get all places ?item=laptop&places=Bangalore&places=Chennai&places=Mumbai and similarly get other fields from query string and then bind it to your class.

 string[] places = req.Query["places"].ToArray();
