Hello,
I have an Enum and a Generic.List(Of Enum)
1 Public Enum Mode
2 Count
3 Day
4 Month
5 End Enum
How can I loop, in the generic list, from the last item that was added
to the first item that was added and remove the duplicated values.
For example, if I add the following items:
1 Dim gl As New Generic.List(Of Mode)
2 gl.Add(Mode.Count)
3 gl.Add(Mode.Month)
4 gl.Add(Mode.Day)
5 gl.Add(Mode.Count)
6 gl.Add(Mode.Day)
I want to remove the items added in 5 and 6 because they are repeated
and they were added last.
Thanks,
Miguel

Miguel,
it might make more sense to restrict adding duplicates than to remove
them after adding.... http://msdn2.microsoft.com/en-us/library/ms132319.aspx
Look at the Example paragraph,.

I agree with OJ. However if there is a reason why you can not do this then a
way to remove duplicates from the list is sort the list with the sort
function and then call the RemoveAll function with a predicate that compares
the previous mode with the current mode shown below:
private static Mode temp;
private static bool RemoveDuplicate(Mode currentMode)
{
bool isDuplicate;
if (temp == currentMode)
{
isDuplicate = false;
}
else
{
isDuplicate = true;
}
temp = currentMode;
return isDuplicate;
}
list.sort();
list.RemoveAll(RemoveDuplicate);
