Ejemplos

En el ejemplo siguiente se crea una clase personalizada ProviderConfigSettings , que se deriva de la ProviderConfigurationSettings clase . En el ejemplo se cargan e inicializan las opciones de configuración del proveedor y, a continuación, se usa el GetSettings método para obtener los pares clave-valor. Por último, el Validate método comprueba si hay validación.

namespace ConfigSnippets {
    class Program {
        static void Main(string[] args) {
            ProviderConfigSettings providerConfigSettings = new ProviderConfigSettings();
            // Load the settings.
            string[] arraysettings = { 
                "key0", "value0", 
                "key1", "value1", 
                "key2", "value2" 
            };
            providerConfigSettings.LoadSettings(arraysettings);
            Console.WriteLine("\nLoadSettings count: " + arraysettings.Length);

            // Display the settings.
            IDictionary<string, string> settings;
            settings = (IDictionary<string, string>)providerConfigSettings.GetSettings();
            Console.WriteLine("There are " + settings.Count +
                " key value pairs in ProviderConfigSettings.");
            foreach (KeyValuePair<string, string> keyValuePair in settings) {
                Console.WriteLine("  " + keyValuePair.Key + ": " + keyValuePair.Value);
            }

            // Perform a validation check on the provider configuration settings.
            string newmessage;
            bool retval = providerConfigSettings.Validate(out newmessage);
            Console.WriteLine("\nValidation returns a " + retval);
            Console.WriteLine("Validation message: " + newmessage);
        }

        public class ProviderConfigSettings : ProviderConfigurationSettings {
            IDictionary<string, string> _settings = new Dictionary<string, string>();

            // overrides the abstract Settings property.
            protected override System.Collections.IDictionary Settings {
                get {
                    return (IDictionary)_settings;
                }
            }

            // Overrides the abstract Validate method.
            public override bool Validate(out string message) {
                // Perform a validation check. If the key pairs collection
                // contains more than three pairs, pass a return value of 
                // false and a failure message.
                if (_settings.Count < 4) {
                    message = "Validation succesful";
                    return true;
                } else {
                    message = "Validation failed - too many key value pairs";
                    return false;
                }
            }
        }
    }
}
