EventDataAttribute 类

定义

指定要传递给 Write<T>(String, EventSourceOptions, T) 方法的类型。Specifies a type to be passed to the Write<T>(String, EventSourceOptions, T) method.

public ref class EventDataAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Struct, Inherited=false)]
public class EventDataAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Struct, Inherited=false)>]
type EventDataAttribute = class
    inherit Attribute

属性

注解

Write 要求 T 为匿名类型或使用特性进行标记 EventDataAttributeWrite requires T to be an anonymous type or marked with the EventDataAttribute attribute. 此外,的属性 T 必须是受支持的属性类型; 简单的框架类型(如、、、、 Int16 Int32 Int64 String Guid DateTimeDateTimeOffset )或基元类型的数组。In addition, the properties of T must be a supported property type; either a simple framework type such as Int16, Int32, Int64, String, Guid, DateTime or DateTimeOffset, or an array of primitive types.

构造函数

EventDataAttribute()

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

属性

Name

如果未显式命名事件类型或属性,则获取或设置要应用于事件的名称。Gets or sets the name to apply to an event if the event type or property is not explicitly named.

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)

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)
GetType()

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

(继承自 Object)
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.
