FormAttribute 类
定义
表示属性,其指定模型绑定的值由表格字段提供。Represents an attribute that specifies that values for model binding are provided by a form field.
public ref class FormAttribute sealed : System::Web::ModelBinding::ValueProviderSourceAttribute, System::Web::ModelBinding::IUnvalidatedValueProviderSource
[System.AttributeUsage(System.AttributeTargets.Parameter, AllowMultiple=false, Inherited=false)]
public sealed class FormAttribute : System.Web.ModelBinding.ValueProviderSourceAttribute, System.Web.ModelBinding.IUnvalidatedValueProviderSource
[<System.AttributeUsage(System.AttributeTargets.Parameter, AllowMultiple=false, Inherited=false)>]
type FormAttribute = class
inherit ValueProviderSourceAttribute
interface IUnvalidatedValueProviderSource
interface IValueProviderSource
Public NotInheritable Class FormAttribute
Inherits ValueProviderSourceAttribute
Implements IUnvalidatedValueProviderSource

构造函数
| FormAttribute() |
初始化 FormAttribute 类的新实例。Initializes a new instance of the FormAttribute class. |
| FormAttribute(String) |
使用指定的形式字段名称初始化 FormAttribute 类的新实例。Initializes a new instance of the FormAttribute class using the specified form field name. |
属性
| FieldName |
获取窗体字段的名称。Gets the name of the form field. |
| TypeId |
在派生类中实现时,获取此 Attribute 的唯一标识符。When implemented in a derived class, gets a unique identifier for this Attribute. (继承自 Attribute) |
| ValidateInput |
获取或设置一个值,该值指示是否验证窗体数据。Gets or sets a value that indicates whether the form data is validated. |
方法
| Equals(Object) |
返回一个值,该值指示此实例是否与指定的对象相等。Returns a value that indicates whether this instance is equal to a specified object. (继承自 Attribute) |
| GetHashCode() |
返回此实例的哈希代码。Returns the hash code for this instance. (继承自 Attribute) |
| GetModelName() |
获取模型名称。Gets the model name. |
| GetType() |
获取当前实例的 Type。Gets the Type of the current instance. (继承自 Object) |
| GetValueProvider(ModelBindingExecutionContext) |
获取值提供程序。Gets the value provider. |
| IsDefaultAttribute() |
在派生类中重写时,指示此实例的值是否是派生类的默认值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (继承自 Attribute) |
| Match(Object) |
当在派生类中重写时,返回一个指示此实例是否等于指定对象的值。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (继承自 Attribute) |
| MemberwiseClone() |
创建当前 Object 的浅表副本。Creates a shallow copy of the current Object. (继承自 Object) |
| ToString() |
返回表示当前对象的字符串。Returns a string that represents the current object. (继承自 Object) |
显式接口实现
| _Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr) |
将一组名称映射为对应的一组调度标识符。Maps a set of names to a corresponding set of dispatch identifiers. (继承自 Attribute) |
| _Attribute.GetTypeInfo(UInt32, UInt32, IntPtr) |
检索对象的类型信息,然后可以使用该信息获取接口的类型信息。Retrieves the type information for an object, which can be used to get the type information for an interface. (继承自 Attribute) |
| _Attribute.GetTypeInfoCount(UInt32) |
检索对象提供的类型信息接口的数量(0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1). (继承自 Attribute) |
| _Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr) |
提供对某一对象公开的属性和方法的访问。Provides access to properties and methods exposed by an object. (继承自 Attribute) |
