25. Data Access - Examples Public Function GetProductsInCategory(ByVal Category As Integer) As DataSet ' Create the Database object, using the database instance with the ' specified logical name. This is mapped to a connection string in ' the configuration file Dim db As Database = DatabaseFactory.CreateDatabase("Sales") ' Invoke the stored procedure with one line of code! return db.ExecuteDataSet("GetProductsByCategory", Category) ' Note: connection was closed by ExecuteDataSet method call End Function public Dataset GetProductsInCategory(string connectionString, int category) { // Create the Database object, using the specified connection string SqlDatabase db = new SqlDatabase(connectionString); // Invoke the stored procedure with one line of code! return db.ExecuteDataSet("GetProductsByCategory", category); // Note: connection was closed by ExecuteDataSet method call }

38. Validation Example [StringLengthValidator(1, 50, Ruleset=&quot; RuleSetA &quot;, MessageTemplate=&quot; Last Name must be 1-50 characters &quot;)] public string LastName { get { return lastName; } set { lastName = value ; } } [RegexValidator( @&quot;+([-+.']+)*@+([-.]+)*+([-.]+)*&quot; , MessageTemplate=&quot; Invalid e-mail address &quot;, Ruleset=&quot; RuleSetA &quot;)] public string Email { get { return email; } set { email = value ; } } Validator<Customer> validator = ValidationFactory.CreateValidator<Customer>(&quot;Ruleset&quot;); ValidationResults results = validator.Validate(customer); if (!results.IsValid) { foreach (ValidationResult result in results) { Console.WriteLine(&quot;Message={0}, Key={1}, &quot;Tag={2}&quot;, result.Message, result.Key.ToString(), result.Tag == null ? &quot;null&quot; : &quot;amp;quot;&quot; + result.Tag.ToString() + &quot;amp;quot;&quot;); } } Specify validation rules in attributes… … or in configuration Validate objects and process results

42. Policy Injection Example public class BankAccount : MarshalByRefObject { // Constructors and fields omitted [ValidationCallHandler] public void Deposit([RangeValidator(typeof(Decimal), &quot;0.0&quot;, RangeBoundaryType.Exclusive, &quot;0.0&quot;, RangeBoundaryType.Ignore)] decimal depositAmount) { balance += depositAmount; } } BankAccount account = PolicyInjection.Create<BankAccount>(customerId); account.Deposit(1234.56M); Write classes that extend MBRO or implement an interface Apply Handlers using attributes if desired Apply Policies using configuration if desired Create objects using PolicyInjection class Call your methods the usual way
