Exemples

L’exemple de code suivant montre comment utiliser le RegexStringValidator type .

using System;
using System.Configuration;

namespace Microsoft.Samples.AspNet.Validators
{
  class UsingRegexStringValidator
  {
    static void Main(string[] args)
    {
      // Display title.
      Console.WriteLine("ASP.NET Validators");
      Console.WriteLine();

      // Create RegexString and Validator.
      string testString = "someone@example.com";
      string regexString = 
       @"^[a-zA-Z\.\-_]+@([a-zA-Z\.\-_]+\.)+[a-zA-Z]{2,4}$";
      RegexStringValidator myRegexValidator = 
       new RegexStringValidator(regexString);

      // Determine if the object to validate can be validated.
      Console.WriteLine("CanValidate: {0}",
        myRegexValidator.CanValidate(testString.GetType()));

      try
      {
        // Attempt validation.
        myRegexValidator.Validate(testString);
        Console.WriteLine("Validated.");
      }
      catch (ArgumentException e)
      {
        // Validation failed.
        Console.WriteLine("Error: {0}", e.Message.ToString());
      }

      // Display and wait
      Console.ReadLine();
    }
  }
}

Remarques

L’objet RegexStringValidator contient les règles nécessaires pour valider un objet string basé sur une expression régulière. Les règles sont établies lorsqu’un instance de cette classe est créé.

La CanValidate méthode détermine si le type d’objet en cours de validation correspond au type attendu. L’objet à valider est passé en tant qu’argument à la Validate méthode .
