SupportsEventValidationAttribute Class


定义元数据特性,Web 服务器控件使用它来表明支持事件验证。Defines the metadata attribute that Web server controls use to indicate support for event validation. 无法继承此类。This class cannot be inherited.

public ref class SupportsEventValidationAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Class, AllowMultiple=false)]
public sealed class SupportsEventValidationAttribute : Attribute
type SupportsEventValidationAttribute = class
    inherit Attribute
Public NotInheritable Class SupportsEventValidationAttribute
Inherits Attribute


事件验证可防止伪造的回发到 ASP.NET 网页,并可通过 EnableEventValidation page 指令启用。Event validation prevents forged postbacks to an ASP.NET Web page and can be enabled through the EnableEventValidation page directive.

Notes to Inheritors

如果未定义 SupportsEventValidationAttribute 属性,自定义控件不会自动参与事件验证。If you do not define the SupportsEventValidationAttribute attribute, your custom control does not automatically participate in event validation. 不过,控件可以显式调用 ValidateEvent(String)However, your control can explicitly call ValidateEvent(String). 如果处理事件注册和验证,请调用 ValidateEvent(String),然后不需要在控件上定义此特性。If you handle event registration and validation, call ValidateEvent(String), and then you do not need to define this attribute on the control.



初始化 SupportsEventValidationAttribute 类的新实例。Initializes a new instance of the SupportsEventValidationAttribute class.



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.

(Inherited from Attribute)



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.

(Inherited from Attribute)

返回此实例的哈希代码。Returns the hash code for this instance.

(Inherited from Attribute)

获取当前实例的 TypeGets the Type of the current instance.

(Inherited from Object)

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.

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.

Explicit Interface Implementations

_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.

(Inherited from 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.

(Inherited from Attribute)

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).

(Inherited from Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)
