How can I assign the value selected in a listbox to an enum var?

Question

I want to avoid the kludginess of:

private void listBoxBeltPrinters_SelectedIndexChanged(object sender, System.EventArgs e)
{
    string sel = string listBox         


        

Answer 1

You could try something like this

Array values = Enum.GetValues(typeof(BeltPrinterType));//If this doesn't help in compact framework try below code
Array values = GetBeltPrinterTypes();//this should work, rest all same
foreach (var item in values)
{
    listbox.Items.Add(item);
}

private static BeltPrinterType[] GetBeltPrinterTypes()
{
    FieldInfo[] fi = typeof(BeltPrinterType).GetFields(BindingFlags.Static | BindingFlags.Public);
    BeltPrinterType[] values = new BeltPrinterType[fi.Length];
    for (int i = 0; i < fi.Length; i++)
    {
        values[i] = (BeltPrinterType)fi[i].GetValue(null);
    }
    return values;
    }

private void listBoxBeltPrinters_SelectedIndexChanged(object sender, System.EventArgs e)
{
    if(!(listBoxBeltPrinters.SelectedItem is BeltPrinterType))
    {
        return;
    }
    PrintUtils.printerChoice = (BeltPrinterType)listBoxBeltPrinters.SelectedItem;
}

With Enum.Parse you could convert from a string to a Enum.

PrintUtils.printerChoice = (PrintUtils.BeltPrinterType)Enum.Parse(typeof(PrintUtils.BeltPrinterType),listBoxeltPrinters.SelectedItem);

Also there is method Enum.TryParse which returns a bool indicating if the parse is succeeded.
