c# - JavaScriptSerializer has registerconverters, how to call base deserialize method in RegisterConverts Class -

i have javascriptserializer registerconverters class serialize datatime. in same class have deserialize method throws notimplementedexception. registerconverters class working fine when serializing object.

when using same javascriptserializer object deserialize json object required class object throwing notimplementedexception.

here don't want use deserilize method of registerconverters class. how can achive that? work new javascriptserializer object has no registerconverters when deserializing.

public class defaultnullpropertiesconverter : javascriptconverter {     public override object deserialize(idictionary<string, object> dictionary, type type, javascriptserializer serializer)     {         throw new notimplementedexception();     }      public override idictionary<string, object> serialize(object obj, javascriptserializer serializer)     {         var jsonexample = new dictionary<string, object>();         foreach (var prop in obj.gettype().getproperties())         {             //check if decorated scriptignore attribute             bool ignoreprop = prop.isdefined(typeof(scriptignoreattribute), true);              var value = prop.getvalue(obj, bindingflags.public, null, null, null);             if (value != null && !ignoreprop)             {                 if (value.gettype().fullname == "system.datetime" && convert.todatetime(value) == datetime.minvalue)                     continue;                 else if (value.gettype().fullname == "system.datetime")                     jsonexample.add(prop.name, convert.todatetime(value).tostring("yyyy-mm-dd"));                 else                     jsonexample.add(prop.name, value);             }         }          return jsonexample;     }      public override ienumerable<type> supportedtypes     {         { return gettype().assembly.gettypes(); }     }  } 

now when call deserialize method:

var restgeocoderesponse rgcr = jss.deserialize<restgeocoderesponse>(result);  

this should not call deserialize method of defaultnullpropertiesconverter class. deserialize doesnot have registerconverts.

so first question ask passing registerconverters method? did write own javascriptconverter handle datetime serialization , deserialization. if javascriptconverter class wrote has throws notimplementedexception in deserialize method.

if using 3rd party javascriptconverter @ source code or if not have source code decompile source using tool dotpeek jetbrains or justdecompile telerik
