備註

BaseChannelObjectWithProperties是和BaseChannelSinkWithProperties的BaseChannelWithProperties基類。

BaseChannelWithProperties 和 BaseChannelSinkWithProperties 可用來作為通道和通道接收的基類，這些通道和通道接收會提供具名屬性。

BaseChannelObjectWithProperties 處理向通道物件要求其屬性的複雜工作。

這個類別會在類別層級建立連結需求和繼承需求。 SecurityException當立即呼叫端或衍生類別沒有基礎結構權限時，就會擲回。如需安全性需求的詳細資訊，請參閱連結需求和繼承需求。

給實施者的注意事項

當您繼承自 BaseChannelObjectWithProperties時，必須覆寫 Keys 屬性和 Item[Object] 屬性。

建構函式

BaseChannelObjectWithProperties()

初始化 BaseChannelObjectWithProperties 類別的新執行個體。

屬性

Count	取得與通道物件相關聯的屬性數目。
IsFixedSize	取得值，指出可輸入到通道物件的屬性數目是否為固定的。
IsReadOnly	取得值，指出通道物件中的屬性集合是否為唯讀。
IsSynchronized	取得值，指出通道物件屬性的字典是否已經同步 (Synchronize)。
Item[Object]	在衍生類別中覆寫時，取得或設定與指定之索引鍵相關聯的屬性。
Keys	在衍生類別中覆寫時，取得與通道物件屬性相關聯之索引鍵的 ICollection。
Properties	取得與通道物件相關聯之通道屬性的 IDictionary。
SyncRoot	取得可用來對 BaseChannelObjectWithProperties 同步存取的物件。
Values	取得與通道物件相關聯之屬性值的 ICollection。

方法

Add(Object, Object)	擲回 NotSupportedException。
Clear()	擲回 NotSupportedException。
Contains(Object)	傳回值，指出通道物件是否包含與指定之索引鍵相關聯的屬性。
CopyTo(Array, Int32)	擲回 NotSupportedException。
Equals(Object)	判斷指定的物件是否等於目前的物件。 (繼承來源 Object)
GetEnumerator()	傳回 IDictionaryEnumerator，其列舉與通道物件相關聯的所有屬性。
GetHashCode()	做為預設雜湊函式。 (繼承來源 Object)
GetType()	取得目前執行個體的 Type。 (繼承來源 Object)
MemberwiseClone()	建立目前 Object 的淺層複製。 (繼承來源 Object)
Remove(Object)	擲回 NotSupportedException。
ToString()	傳回代表目前物件的字串。 (繼承來源 Object)

明確介面實作

IEnumerable.GetEnumerator()

傳回 IEnumerator，其列舉與通道物件相關聯的所有屬性。

擴充方法

Cast<TResult>(IEnumerable)	將 IEnumerable 的項目轉換成指定的型別。
OfType<TResult>(IEnumerable)	根據指定的型別來篩選 IEnumerable 的項目。
AsParallel(IEnumerable)	啟用查詢的平行化作業。
AsQueryable(IEnumerable)	將 IEnumerable 轉換成 IQueryable。
