How to iterate a Dictionary(Of Integer, List(Of MyClass))

Hello  there,

I am experiencing some severe problems, when trying to iterate  a dictionary of type Dictionary(Of Integer, List (Of clsMyClass) ).

How can I access the list in a single Dictionary object ?

Public Sub TestMe()
        Dim EOL As String = vbCrLf

        Dim strText = System.IO.File.ReadAllText(_FileName)

        Dim _lines As String()
        _lines = Split(strText, EOL)

        Dim EDIFileReferences As New Dictionary(Of Integer, List(Of clsEDI_FileImportMappingClass))
		'(1)
        For row As Integer = 0 To _lines.Count - 1
            Dim line As String
            line = _lines(row)
            Dim SEGMDESC As String = Left(line, 3)
            Dim Filter As String = line.Substring(3, 2)
            Dim Mapping As List(Of clsEDI_FileImportMappingClass) = Profil.getEdiSegCols(SEGMDESC, Filter)
            Dim x As New List(Of clsEDI_FileImportMappingClass)
            x = MapContentsOfImportedEdiFile(line, Mapping)
            EDIFileReferences.Add(row, New List(Of clsEDI_FileImportMappingClass))
            EDIFileReferences(row) = x
		Next
                '!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!		
		' (2) Following fragment is showing only identical contents:
                '!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


        For row As Integer = 0 To EDIFileReferences.Count - 1

            Dim objList As List(Of clsEDI_FileImportMappingClass) = EDIFileReferences(row)
            Dim sout As String : sout = ""
            For x As Integer = 0 To EDIFileReferences(row).Count - 1
                sout = "ROW IN FILE: " & row.ToString & " | SEGMENT: " & EDIFileReferences(row).Item(x).SEGMENT & " | FELD-NR.:" & EDIFileReferences(row).Item(x).EDI_FIELD & " | CONTENTS: " & EDIFileReferences(row).Item(x).CONTENTS.ToString
                Debug.Print(sout)
            Next
        Next

End Sub

' *****************************************************

Public Function MapContentsOfImportedEdiFile(ByVal csvline As String, ByVal ediDBObjMapping As List(Of clsEDI_FileImportMappingClass)) As List(Of clsEDI_FileImportMappingClass)

        Dim x As New List(Of clsEDI_FileImportMappingClass)
        ' Processing ediDBObjMapping 

        ' Return mapped contents
        Return x
   End Function

Dim dictionars As New Dictionary(Of String, Integer)
        dictionars.Add("a", 1)
        dictionars.Add("b", 2)
        dictionars.Add("c", 3)
        dictionars.Add("d", 3)

 Dim pr As KeyValuePair(Of String, Integer)

            Console.WriteLine("{0}, {1}", pr.Key, pr.Value)

Hi Stephan;

This is how to iterate through the List stored in the Dictionary object.
Dim myDictionary As New Dictionary(Of Integer, List(Of clsMyClass))
myDictionary.Add(1, mClass)

'' Get a List of clsMyClass from the Dictionary
Dim theList As List(Of clsMyClass) = myDictionary(1)
'' Iterate through the List of clsMyClass
For Each item As clsMyClass In theList
	Console.WriteLine("Name: {0} and Age: {1}", item.Name, item.Age)
Next
