注解

接收器提供程序数据是元素 (模板) 配置节点中<provider>存储的配置信息的树结构。所有接收器提供程序必须具有一个构造函数， IDictionary 如果想要从配置文件使用属性和其中一个 ICollection 结构。

构造函数

SinkProviderData(String)

初始化 SinkProviderData 类的新实例。

属性

Children	获取一个子 SinkProviderData 节点的列表。
Name	获取与当前 SinkProviderData 对象中的数据关联的接收器提供程序的名称。
Properties	获取可以通过其访问接收器提供程序上属性的字典。

方法

Equals(Object)	确定指定对象是否等于当前对象。 (继承自 Object)
GetHashCode()	作为默认哈希函数。 (继承自 Object)
GetType()	获取当前实例的 Type。 (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ToString()	返回表示当前对象的字符串。 (继承自 Object)
