To delete a specific form, you use the FormsManager class and call the Delete method. The following code deletes a form with the specified formId through the Native API.
DeleteForm( Guid formId )
var formManager = FormsManager.GetManager();
var formToDelete = formManager.GetForms().Where( f => f.Id == formId ).SingleOrDefault();
( formToDelete !=
formManager.Delete( formToDelete );
First, you initialize the FormsManager. Then, you must call GetForms to retrieve all forms and filter them based on the Id property. You assure that the form exists. Finally, you delete the form by calling Delete and save the changes.
