vb.net (or c#) to photoshop batch

Question

Trying to automate Photoshop from .Net application. Works fine with documents, layers, but getting error on batch method:

Dim appRef As Photoshop.Application
appRef = New ApplicationClass
Dim batchOpt As New BatchOptions
batchOpt.Destination = PsBatchDestinationType.psFolder
batchOpt.DestinationFolder = "c:\0\1\"
batchOpt.OverrideOpen = True
batchOpt.OverrideSave = True
batchOpt.SuppressOpen = True
batchOpt.ErrorFile = "c:\mylog.txt"
Dim flNaming(0) As PsFileNamingType
flNaming(0) = PsFileNamingType.psDocumentNameMixed
batchOpt.FileNaming = flNaming
Dim inputFiles(0) As String
inputFiles(0) = "c:\0\myImage.jpg"
appRef.Batch(inputFiles, "AutoLevelsContrast", "Default Actions", batchOpt)

Here "AutoLevelsContrast" is my action.
On batch operation getting exception:
"Illegal argument - argument 1. -Unsupported Variant type"

Type PhotoshopType = Type.GetTypeFromProgID("Photoshop.Application");
            Type PhotoshopBatchOptType = Type.GetTypeFromProgID("Photoshop.BatchOptions");
            dynamic appRef2 = Activator.CreateInstance(PhotoshopType);
            dynamic batchOptions = Activator.CreateInstance(PhotoshopBatchOptType);

            object[] obj = new object[1];
            obj[0] = @"D:\youtimage.tif";

            batchOptions.overrideSave = true;
            batchOptions.overrideOpen = true;
            batchOptions.destination = PsBatchDestinationType.psSaveAndClose;
            appRef2.Batch(obj, ActionSet, ActionName, batchOptions);

The array of images needs to be a true object[] a string array will not work.
