To convert a string to an enum you need to use Enum.Parse

Siren.PfundMemberWebServices.Emirates EM = (Siren.PfundMemberWebServices.Emirates)Enum.Parse(typeof(Siren.PfundMemberWebServices.Emirates), cmbemirate.SelectedValue);

Need `typeof(Siren.PfundMemberWebServices.Emirates)` for the first parameter of `Parse()` – Matthew Watson Jan 20 '14 at 12:31

Your question is not complete but the InvalidCastException occurs when an explicit cast is applied. But the type is not in the same path of the type hierarchy. The cast does not succeed.

Use:

Siren.PfundMemberWebServices.Emirates EM = (Siren.PfundMemberWebServices.Emirates)Enum.Parse(typeof(Siren.PfundMemberWebServices.Emirates), cmbemirate.SelectedValue);

If you have int values with combobox then you can try:

Siren.PfundMemberWebServices.Emirates EM = (Siren.PfundMemberWebServices.Emirates)Convert.ToInt32(cmbemirate.SelectedValue)
