How to convert an object collection to an array of Enum

Question

I seem to be stuck trying to convert a collection of ListBox items to Enum.

Here is my code

 ChannelCodeType[] ChannelCodes = lbSearch.SelectedItems;


public enum ChannelCodeType {

        /// <remarks/>
        XYZ1,

        /// <remarks/>
        XYZ1_KIDS,

        /// <remarks/>
        XYZ1_PRIME,

        /// <remarks/>
        XYZ13,

        /// <remarks/>
        XYZ14,
    }

I am trying to pass the values (selecteditems) back to the ChannelCodes

The way you put this makes no sense. You want to set an array of an enum type to a set of values from a dropdown of some sort. You don't want to pass anything to an enum. — John Saunders

The SelectedItems property is most likely a collection of type Object.

Try casting the collection back to the original type:

ChannelCodeType[] ChannelCodes
    = lbSearch.SelectedItems.Cast<ChannelCodeType>().ToArray();

I'm assuming lbSearch is a ListBox and that it's been filled with ChannelCodeType values.

If Baldrick is right, and you've got string representations of the ChannelCodeType enum values, then you may need to modify the code to parse the strings back to the original enum:

ChannelCodeType[] ChannelCodes
  = lbSearch.SelectedItems
            .Cast<string>()
            .Select(c => (ChannelCodeType)Enum.Parse(typeof(ChannelCodeType), c))
            .ToArray();

If I had to guess, I'd suggest the OP might have the string representations of the enum as the underlying object in the ListBox. In which case, you'd need to do something like this: stackoverflow.com/questions/16100/…
