Problem with Simplist.Add in C#

I'm having a problem with adding to a SimpleList in C#.

Here is the segment of C# code where I’m having trouble.

SimpleList FreeListItems = LineItem[“orc_free_items”] as SimpleList;

Dictionary FreeItem = new Dictionary();

FreeItem[“_sku”] = “12345”;

FreeListItems.Add(FreeItem); <--------------- ERROR Line:

Error from Visual Studio:

The best overloaded method match for
‘Microsoft.CommerceServer.Runtime.IsimpleList.Add(ref object)’has
some invalid arguments.

Tried the following and it seemed to work. Seems like you need to
create the com object using in non-interaop MSCS objects first and set
a typed reference to that new object and use that type reference to
build up the object. Then use the com reference for the Simplelist.Add
method.

object objNewDict = Server.CreateObject("Commerce.Dictionary")
Dictionary FreeItem = objNewDict as Dictionary;
FreeItem["_sku"] = "12345";

SimpleList FreeListItems = LineItem["orc_free_items"] as
SimpleList;
FreeListItems.Add(ref objNewDict);

If anyone knows a better way to do this or sees a problem with this
please post a reply.
Thanks...

The code you have is correct.
