C# Reflection Invoke - Returns Generic Object { Type } - Need Type

Question

I have a stored procedure call interface that I'm using to handle results from stored procedures with entity (using Translate method to translate the results of our stored procedure into entities that can be tracked and used in EF as normal)

Here's the basic code...

List<object> current = new List<object>();
object item = ((Type)currenttype.Current).GetConstructor(System.Type.EmptyTypes).Invoke(new object[0]);

ObjectContext actualContext = ((IObjectContextAdapter)context).ObjectContext;
string className = "";
EntityContainer container = null;
string setName = "";

className = ((Type)currenttype.Current).ToString();
container = actualContext.MetadataWorkspace.GetEntityContainer(((IObjectContextAdapter)context).ObjectContext.DefaultContainerName, DataSpace.CSpace);
setName = (from meta in container.BaseEntitySets
           where meta.ElementType.FullName == className
           select meta.Name).FirstOrDefault();


var t = typeof(ObjectContext).GetMethod("Translate", new Type[] { typeof(DbDataReader), typeof(string), typeof(MergeOption) }).MakeGenericMethod(item.GetType()).Invoke(actualContext, new object[] { reader, setName, MergeOption.AppendOnly });

The issue is that I can't do anything with 't' that I want, it's type is listed as
object {System.Data.Entity.Core.Objects.ObjectResult<POCOClass>} . I can't call any of the normal methods that I can normally on the ObjectResult type such as ToArray or ToList .

I need a way to convert it into System.Data.Entity.Core.Objects.ObjectResult<POCOClass> . The difference being that 't' is listed as type object first.

I cannot use any strongly typed casts because the types will change depending on the stored procedure. I've tried using the dynamic keyword instead of var for t and I've also tried using Convert.ChangeType . It never changes from the object base type. dynamic t returns this the following error:

'System.Data.Entity.Core.Objects.ObjectResult<POCOClass>' does not contain a definition for 'ToList'

Thought I know for a fact it does...

To clear up confusion, here's a watch screenshot. The first line is what's being returned, I want it to be like the second (see Type column).

Edit : might be getting closer... I added this:

var listedT = typeof(Enumerable).GetMethod("ToList").MakeGenericMethod(item.GetType()).Invoke(null, new object[] { t });
current.AddRange(listedT); // Error here...

listedT becomes a object {System.Collections.Generic.List<ReportCatalog.Models.Catalog_Reports>} and I get the error, cannot convert from object to System.Collections.Generic.IEnumerable<object>.

Answer 1

Since ObjectResult<T> implements also the non-generic IEnumerable interface, cast it to this type and enumerate it.

var e = (IEnumerable)t;
foreach (object o in e) {
    //TODO: use o
}
