2. Setting an optional parameter to empty:
public void MyMethod(int id, string name = "") { // do something with the id and name parameters }
3. Returning an optional empty value from a method:
public Optional GetOptionalString(int id) { if (id == 0) { return Optional.Empty(); } else { return Optional.Of("some value"); } }
