There's nothing to prevent an anon method calling an external method which in turn calls the method in which the anon method resides, which duly invokes the anon method - voila indirect recursion.

Function f = null;
f = delegate() { f(); }

comboBox1.Items.Add("US");
comboBox1.Items.Add("CA");
//store it in a string
string value = comboBox1.SelectedIndex.ToString();
//store it as an int
int value = comboBox1.SelectedIndex;

public struct CountryWithid {
   public string Country;
   public int Id;

   public CountryWithid(string country, int id) {
      this.Country = country;
      this.Id = id;
   }

   public override string ToString() {
      return this.Country;
   }
}

//adding items
comboBox.Items.Add(new CountryWithId("US", 8));
comboBox.Items.Add(new CountryWithId("Canada", 3));

//retrieving selected Id
int selectedid = ((CountryWithId)comboBox.SelectedItem).Id;
