範例

下列程式碼範例示範數個成員ReadOnlyCollection<T>類別。The following code example demonstrates several members of the ReadOnlyCollection<T> class. 此程式碼範例會建立List<T>的字串,並將四個恐龍名稱加入至它。The code example creates a List<T> of strings and adds four dinosaur names to it. 在程式碼範例接著會包裝的清單中ReadOnlyCollection<T>The code example then wraps the list in a ReadOnlyCollection<T>.

之後示範CountContainsItem[Int32],和IList.IndexOf成員,在程式碼範例顯示ReadOnlyCollection<T>只是原始List<T>藉由新增新的項目至List<T>和顯示的內容ReadOnlyCollection<T>After demonstrating the Count, Contains, Item[Int32], and IList.IndexOf members, the code example shows that the ReadOnlyCollection<T> is just a wrapper for the original List<T> by adding a new item to the List<T> and displaying the contents of the ReadOnlyCollection<T>.

最後,程式碼範例會建立陣列大於集合,並使用CopyTo方法,將集合的項目插入陣列的中間。Finally, the code example creates an array larger than the collection and uses the CopyTo method to insert the elements of the collection into the middle of the array.

備註

執行個體ReadOnlyCollection<T>泛型類別永遠是唯讀的。An instance of the ReadOnlyCollection<T> generic class is always read-only. 是唯讀的集合是可防止修改集合的包裝函式集合因此,如果基礎集合進行變更,唯讀的集合會反映這些變更。A collection that is read-only is simply a collection with a wrapper that prevents modifying the collection; therefore, if changes are made to the underlying collection, the read-only collection reflects those changes. 請參閱Collection<T>這個類別的可修改版本。See Collection<T> for a modifiable version of this class.

執行緒安全性

公用靜態 (Shared Visual Basic 中) 的這種類型的成員都是安全執行緒。Public static (Shared in Visual Basic) members of this type are thread safe. 不保證任何執行個體成員是安全執行緒。Any instance members are not guaranteed to be thread safe.

AReadOnlyCollection<T>可支援多個讀取器同時,只要不修改集合。A ReadOnlyCollection<T> can support multiple readers concurrently, as long as the collection is not modified. 即便如此,透過集合列舉是本質上並非安全執行緒程序。Even so, enumerating through a collection is intrinsically not a thread-safe procedure. 若要確保列舉期間的執行緒安全性,您可以在整個列舉期間鎖定集合。To guarantee thread safety during enumeration, you can lock the collection during the entire enumeration. 若要讓多重執行緒能夠存取集合以便進行讀取和寫入,您必須實作自己的同步處理。To allow the collection to be accessed by multiple threads for reading and writing, you must implement your own synchronization.
