Если вы используете ASP.Net MVC 3
, вы можете использовать System.Web.Mvc.CompareAttribute
.
Если вы используете ASP.Net 4.5
, он находится в System.Component.DataAnnotations
.
[Required(ErrorMessage = "Password is required")]
[StringLength(255, ErrorMessage = "Must be between 5 and 255 characters", MinimumLength = 5)]
[DataType(DataType.Password)]
public string Password { get; set; }
[Required(ErrorMessage = "Confirm Password is required")]
[StringLength(255, ErrorMessage = "Must be between 5 and 255 characters", MinimumLength = 5)]
[DataType(DataType.Password)]
[Compare("Password")]
public string ConfirmPassword { get; set; }
EDIT: для MVC2
Используйте приведенную ниже логику, используйте атрибут PropertiesMustMatch
вместо Compare
. [Ниже код копируется из шаблона проекта MVCApplication
по умолчанию.]
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Property, AllowMultiple = true, Inherited = true)]
public sealed class PropertiesMustMatchAttribute : ValidationAttribute
{
private const string _defaultErrorMessage = "'{0}' and '{1}' do not match.";
private readonly object _typeId = new object();
public PropertiesMustMatchAttribute(string originalProperty, string confirmProperty)
: base(_defaultErrorMessage)
{
OriginalProperty = originalProperty;
ConfirmProperty = confirmProperty;
}
public string ConfirmProperty { get; private set; }
public string OriginalProperty { get; private set; }
public override object TypeId
{
get
{
return _typeId;
}
}
public override string FormatErrorMessage(string name)
{
return String.Format(CultureInfo.CurrentUICulture, ErrorMessageString,
OriginalProperty, ConfirmProperty);
}
public override bool IsValid(object value)
{
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(value);
object originalValue = properties.Find(OriginalProperty, true /* ignoreCase */).GetValue(value);
object confirmValue = properties.Find(ConfirmProperty, true /* ignoreCase */).GetValue(value);
return Object.Equals(originalValue, confirmValue);
}
}
