how to use index in data dictionary?

Question

I am using a data dictionary in VB.NET windows application.

I am trying to get the data from dictionary using the for loop.

ex. I have below dictionary table and I want to get the values using the for loop.

AAA - "0"   
BBB - "0" 
CCC - "0' 
DDD - "0"

 For i As Integer = 0 To CatDictionaryNEW1.Count
' for each i I want to fetch the values using index of data dictionary
' when i = 0 then AAA should return
' when i =1 then BBB should return 
' and so on....
 next

How to do this ?

can you show how you declared the dictionary and how you add to it? — Ňɏssa Pøngjǣrdenlarp, Oct 23 '13 at 12:19

you do not need to iterate the entire dictionary to test AAA or BBB (they are not Lists or Arrays):

 If CatDictionaryNEW1("AAA") = 0 Then
      do whatever
 End If

 If CatDictionaryNEW1("BBB") = 1 Then
      do whatever
 End If

You would need to walk thru the entire dictionary if you needed to find WHICH item or element contained a certain value:

  For each kvp as KeyValuePair in myDict
       if kvp.Value = MagicValue then
           Return kvp.Key
       End if
  Next
