How do you access the output of iGpDispatch.ListIndexes method in VB.net?

Hello. I am working on a program that will list the indexes in a featureclass. I am trying to use the iGpDispatch method of the geoprocessing object. I think I am doing good up to the point where I run the actual ???listindexes??? method. I am not how to handle the results of this method.
Do I dim an object and set it to the value of pGpDispatch? Like

dim objObject as pGpDispatch.listindexes(pGxObject)???
and then just type for each index in objObject.index
strIndex = objObject.Nameetc.

or do I need to do a
With pGpDispatch.listindexes(pGxObject)

and then get the properties I want? I played around with several ways, but the lack of IntelliSense suggestions leads me to believe I am wrong.

Here is the code I have so far. Currently it is a standalone windows form executable so I am getting the feature class from a GxDialog and making it into a GxOBject.

Any suggestions on ways to go would be most appreciated!

Code:

Imports ESRI.ArcGIS.Catalog
Imports ESRI.ArcGIS.CatalogUI
Imports ESRI.ArcGIS.Geoprocessing

Public Class IndexBuilder_Startup

    Private Sub cmdGetFC_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdGetFC.Click
        Dim pEnumGX As IEnumGxObject
        Dim pGxDialog As IGxDialog = New GxDialogClass
        With pGxDialog
            .Title = "Choose File To Search For Indexes On"
            .StartingLocation = ???\\DataDrive\???
            .ObjectFilter = GetFilter()
        End With

        If Not pGxDialog.DoModalOpen(0, pEnumGX) Then
            Exit Sub
        End If

        Dim objGxObject As IGxObject = pEnumGX.Next
        TextBox1.Text = objGxObject.Name

        Dim gp As IGeoProcessor
        gp = New GeoProcessor

        Dim pDispatch As IGpDispatch
        pDispatch = gp

        '' This is where i am stuck.  

        objGxObject = pDispatch.ListIndexes(objGxObject)
        For Each index In objGxObject.index
        ' ???????
        Next
    End Sub

    Private Function GetFilter() As Object
       Dim objFilter As IGxObjectFilter = New GxFilterPGDBFeatureClasses
        Return objFilter
    End Function
