注解

BaseChannelObjectWithProperties 是 BaseChannelWithProperties 和 BaseChannelSinkWithProperties 的基类。

BaseChannelWithProperties 和 BaseChannelSinkWithProperties 可用作提供命名属性的通道和通道接收器的基类。

BaseChannelObjectWithProperties 处理询问通道对象属性的复杂任务。

此类在类级别发出链接需求和继承需求。 SecurityException当直接调用方或派生类没有基础结构权限时，将引发。有关安全要求的详细信息，请参阅链接需求和继承要求。

实施者说明

从 BaseChannelObjectWithProperties继承时，必须重写 Keys 属性和 Item[Object] 属性。

构造函数

BaseChannelObjectWithProperties()

初始化 BaseChannelObjectWithProperties 类的新实例。

属性

Count	获取与该信道对象关联的属性的数目。
IsFixedSize	获取一个值，该值指示可以输入到信道对象中的属性的数目是否是固定的。
IsReadOnly	获取一个值，该值指示信道对象中的属性集合是否是只读的。
IsSynchronized	获取一个值，该值指示信道对象属性的字典是否同步。
Item[Object]	在派生类中重写时，获取或设置与指定键关联的属性。
Keys	当在派生类中重写时，获取与信道对象属性关联的键的 ICollection。
Properties	获取与信道对象关联的信道属性的 IDictionary。
SyncRoot	获取一个对象，该对象用于同步对 BaseChannelObjectWithProperties 的访问。
Values	获取与信道对象关联的属性值的 ICollection。

方法

Add(Object, Object)	引发 NotSupportedException。
Clear()	引发 NotSupportedException。
Contains(Object)	返回一个值，该值指示信道对象是否包含与指定键关联的属性。
CopyTo(Array, Int32)	引发 NotSupportedException。
Equals(Object)	确定指定对象是否等于当前对象。 (继承自 Object)
GetEnumerator()	返回 IDictionaryEnumerator，它枚举与该信道对象关联的所有属性。
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)
Remove(Object)	引发 NotSupportedException。
ToString()	返回表示当前对象的字符串。 (继承自 Object)

显式接口实现

IEnumerable.GetEnumerator()

返回 IEnumerator，它枚举与信道对象关联的所有属性。

扩展方法

Cast<TResult>(IEnumerable)	将 IEnumerable 的元素强制转换为指定的类型。
OfType<TResult>(IEnumerable)	根据指定类型筛选 IEnumerable 的元素。
AsParallel(IEnumerable)	启用查询的并行化。
AsQueryable(IEnumerable)	将 IEnumerable 转换为 IQueryable。
