備註

此類別會實作 ICollection 介面。

建構函式

OidCollection()

初始化 OidCollection 類別的新執行個體。

屬性

Count	取得集合中的 Oid 物件數目。
IsSynchronized	取得值，這個值會表示 OidCollection 物件的存取是否為安全執行緒。
Item[Int32]	從 OidCollection 物件取得 Oid 物件。
Item[String]	取得第一個 Oid 物件，該物件包含的 Value 屬性值或 FriendlyName 屬性值與來自 OidCollection 物件的指定字串值相符。
SyncRoot	取得可用來同步處理對 OidCollection 物件之存取的物件。

方法

Add(Oid)	將 Oid 物件加入 OidCollection 物件。
CopyTo(Oid[], Int32)	將 OidCollection 物件複製到陣列中。
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 OidEnumerator 物件，此物件可以用來巡覽 OidCollection 物件。
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)
ToString()	傳回代表目前物件的字串。 (繼承來源 Object)

明確介面實作

ICollection.CopyTo(Array, Int32)	將 OidCollection 物件複製到陣列中。
IEnumerable.GetEnumerator()	傳回 OidEnumerator 物件，此物件可以用來巡覽 OidCollection 物件。

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。
