Question

I was wondering if it is possible to write both the dictionary key and all records associated with the value to string?

However i only get the output of the Key and one item in value (service status)

Answer 1

Sure, just modify your ToString overload.

Public Overrides Function ToString() As String
    Return "Display Name = " & _displayName & ", Service Name = " & _serviceName & ", Status = " & _serviceStatus
End Function

And, if you need ToString to only return the status, then move the above code into a new function (say DisplayValue) and modify your loop to use this instead of ToString:

sbService.AppendLine(item.Key & "| " & item.Value.DisplayValue)
