c# - How to serialize a list of an interface? -


i got object has inherit general interface has list interface property.

going serialize follows problems, xmlserialzer not able determine real types inside of myclass.items list elements. 

using system; using system.collections.generic; using system.linq; using system.runtime.serialization; using system.text; using system.xml; using system.xml.serialization;  namespace mytest {     public interface imyinterface     {         string testproperty { get; set; }     }     public class myclass : imyinterface     {         public string testproperty { get; set; }         public list<imyinterface> items { get; set; }     }     class program     {         static void main(string[] args)         {             myclass obj = new myclass() { testproperty = "test" };             xmlserializer xs = new xmlserializer(typeof(myclass)); // <- throws system.notsupportedexception             using (xmlwriter xw = xmlwriter.create("file.xml", new xmlwritersettings()             {                 encoding = encoding.utf8,                 indent = true,                 newlinehandling = newlinehandling.entitize             }))             {                 xs.serialize(xw, obj);             }         }     } }

how can serialize list<t> t interface?

unfortunately it's not supported out of box, it's doable. have use ixmlserializable interface , write custom serialization. shouldn't difficult - you'd need enumerate through list, underlying type of each object , create new xmlserializer type. deserialization bit more tricky, you'd need parse class names determine runtime types.
