Syntax

C++

[AttributeUsageAttribute(AttributeTargets::Parameter, Inherited = false, 
	AllowMultiple = false)]
public ref class FormAttribute sealed : ValueProviderSourceAttribute, 
	IUnvalidatedValueProviderSource, IValueProviderSource

Constructors

	Name	Description
	FormAttribute()	Initializes a new instance of the FormAttribute class.
	FormAttribute(String^)	Initializes a new instance of the FormAttribute class using the specified form field name.

Properties

	Name	Description
	FieldName	Gets the name of the form field.
	TypeId	When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)
	ValidateInput	Gets or sets a value that indicates whether the form data is validated.

Methods

	Name	Description
	Equals(Object^)	This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)
	GetHashCode()	Returns the hash code for this instance.(Inherited from Attribute.)
	GetModelName()	Gets the model name.(Overrides ValueProviderSourceAttribute::GetModelName().)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	GetValueProvider(ModelBindingExecutionContext^)	Gets the value provider.(Overrides ValueProviderSourceAttribute::GetValueProvider(ModelBindingExecutionContext^).)
	IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)
	Match(Object^)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Explicit Interface Implementations

	Name	Description
	_Attribute::GetIDsOfNames(Guid%, IntPtr, UInt32, UInt32, IntPtr)	Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)
	_Attribute::GetTypeInfo(UInt32, UInt32, IntPtr)	Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)
	_Attribute::GetTypeInfoCount(UInt32%)	Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)
	_Attribute::Invoke(UInt32, Guid%, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)	Provides access to properties and methods exposed by an object.(Inherited from Attribute.)
