How to Pass List<Object> to SOAP API as a request

Question

How to Pass List to SOAP API request from android

I know how to pass normal object, but at the time of passing the List I'm getting following exception Unable to cast object of type 'GTCFWebServices.Models.ToEmail' to type 'System.Collections.Generic.List1[GTCFWebServices.Models.ToEmail]'. This is expected soap xml request I need to pass List< ToEmail > as a request.

Answer 1

It is not possible to pass complex object like a list of complex object as a parameter in SOAP request.

Finally, I passed String concatenating with, (comma) for a list and then API side we separated it and created a list.
