Dictionary and For loop issues in VB

how do I go about getting each value in a dictionary array if this is my dictionary .

        rebDictionary= New Dictionary(Of String, String())

    rebDictionary.Add("wrd", {"yap", "tap"})

i tried For Each rtbval As String In rebDictionary.value

but that does not work at all

The following code iterates through all keys and values. You can select whichever parts you want/don't want:

    For Each kvp As KeyValuePair(Of String, String()) In rebDictionary
        Debug.WriteLine("Key:" + kvp.Key)
        For Each stringValue As String In kvp.Value
            Debug.WriteLine(" Value:" + stringValue)
        Next
    Next

You can just iterate through the keys:

    For Each key As String In rebDictionary.Keys
        Debug.WriteLine("Key:" + key)
    Next

Or through the values:

    For Each value As String() In rebDictionary.Values
        For Each stringValue As String In value
            Debug.WriteLine("value:" + stringValue)
        Next
    Next

But doing either of those probably isn't as useful as you don't know the corresponding key or value and I doubt that iterating through the key value pairs is likely to be much slower.

The values collection property is named Values, so try this:

For Each rtbval As String() In rebDictionary.Values

However, you're gonna iterate over a collection of String(), because your dictionary is Of(String, String()).

You can iterate over keys (which are String): rebDictionary.Keys or use LINQ SelectMany to iterate over flatten list of strings taken from you dictionary Values:

For Each rtbval as String In rebDictionary.Values.SelectMany(Function(x) x)
