Provides an abstract class for classes that implement a validation provider.
Assembly: System.Web.Mvc (in System.Web.Mvc.dll)
Thetype exposes the following members.
|Equals||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|GetTypeDescriptor||Gets a type descriptor for the specified type.|
|GetValidators(ModelMetadata, ControllerContext)||Gets the validators for the model using the metadata and controller context. (Overrides ModelValidatorProvider.GetValidators(ModelMetadata, ControllerContext).)|
|GetValidators(ModelMetadata, ControllerContext, IEnumerable<Attribute>)||Gets the validators for the model using the metadata, the controller context, and a list of attributes.|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
A validation provider provides validation logic for the data model. A validation provider must derive from ModelValidatorProvider. You can inherit from this class if you want to use a custom validator provider or a third-party validator that uses attribute-based metadata. This class performs most of the work that is required in order to implement the ModelValidatorProvider class.
When you implement this class, use the AssociatedMetadataProvider class to implement the metadata provider.
Model provider classes and validator provider classes are loosely coupled. Therefore, they work independently, and have no dependencies on each other.
However, the metadata provider exposes metadata that can be accessed and used by validation providers. For example, the MVC default metadata provider (the DataAnnotationsModelMetadataProvider class) reads the display name of an object, and the display name is used by the DataAnnotationsModelValidatorProvider validation provider when it creates a validation error message.
