NEED HELP!!! Iterating thru embedded dictionaries
I'm porting a VB6 app to .NET, but encountering problems iterating through ALL of my embedded dictionaries:
------VB6 code------:
dim dctOne as new Scripting.Dictionary
dim vOne as Variant
dim vTwo as Variant
'dctOne has Key=unique number, Value=Dictionary
For each vOne in dctOne
'Loop through embeded dictionary related to dctOne's
'current key
For each vTwo in dctOne(vOne)
...........
-------.NET code-----:
dim dctOne as _
new System.Collections.Specialized.HybridDictionary
dim deDictEntryOne as System.Collections.DictioaryEntry
dim deDictEntryTwo as System.Collections.DictioaryEntry
'dctOne has Key=unique number, Value=Dictionary
For each deDictEntryOne in dctOne
'Loop through embeded dictionary related to dctOne's
'current key
For each deDictEntryTwo in dctOne(cstr(deDictEntryOne.key))
--------The .NET code on the last line doesn't compile: "Expression is of type 'System.Object', which is not a collection type." SOOOO I'm not sure what is the correct way to do this in .NET.
I don't want to use object data types at all, and NEED to find the correct way to iterate through MANY LEVELS of a dictionary in .NET. It may be that I cannot use DictionaryEntry structure, but I CAN'T FIND DOCUMENTATION ANYWHERE.
I REALLY NEED AND WOULD REALLY APRECIATE ANY KIND OF ADVICE!!!!!!!!!!!!!
THANKS IN ADVANCE

Would something such as this work for you?
Dim dctOne As New System.Collections.ArrayList()
Dim deDictEntryOne As System.Collections.Hashtable()
For Each deDictEntryOne In dctOne
Next
'or
Dim dctOne1 As New System.Collections.Specialized.HybridDictionary()
Dim deDictEntryOne1 As System.Collections.IDictionaryEnumerator
deDictEntryOne1 = dctOne1.GetEnumerator()
While deDictEntryOne1.MoveNext()
'deDictEntryOne1.Current gets you the current object.
End While
