    public class GetValidateExample
    {
        private readonly SchoolContext _context;

        public GetValidateExample(SchoolContext dataContext)
        {
            // Sets the data context
            _context = dataContext;
        }

        public void Example2()
        {
            // Instantiates a DataStore object with datawindow: d_department.
            var datastore = new DataStore("d_department", _context);

            datastore.Retrieve();

            // Sets the validation rule for the departmentid column: 
            // value must be larger than 0.
            datastore.SetValidate(0, "departmentid > 0");

            // The lower bound of column is 0. 
            // Gets the validation rules for the departmentid column.
            string validation_rule = datastore.GetValidate("departmentid");

            Console.WriteLine("Validation Rule: {0}", validation_rule);

            /*This code produces the following output:
             
            Validation Rule: departmentid > 0:
            */
