部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
若為小型集合，則使用 ListDictionary 實作 IDictionary，在它成為大型集合時，切換為 Hashtable。

備註
對於字典中的元素數目未知的情況，建議使用這個類別。 它利用具有小型集合的 ListDictionary 改善效能，並提供切換至 Hashtable 的彈性，以處理比 更好的 ListDictionary較大集合。
如果集合的初始大小大於 的最佳大小 ListDictionary，則集合會儲存在 中 Hashtable ，以避免將專案從 ListDictionaryHashtable複製到 的額外負荷。
建構函式接受 Boolean 參數，可讓使用者指定集合在比較字串時是否忽略大小寫。 如果集合區分大小寫，它會使用 和 Object.Equals的索引鍵實作Object.GetHashCode。 如果集合不區分大小寫，它會執行簡單的不區分大小寫比較，只遵守不變異文化特性的大小寫規則。 根據預設，集合會區分大小寫。 如需不變異文化特性的詳細資訊，請參閱 System.Globalization.CultureInfo。
索引鍵不能是 Null，但值可以。
foreach Visual Basic 中 C# 語言 (的 語句) For Each 會傳回集合中專案類型的 物件。 因為的每個 HybridDictionary 元素都是索引鍵/值組，所以項目類型不是索引鍵的類型或值的型別。 相反地，項目類型為 DictionaryEntry。 例如：
for each (DictionaryEntry^ de in myHybridDictionary)
{
//...
}
foreach (DictionaryEntry de in myHybridDictionary)
{
//...
}
For Each de In myHybridDictionary
'...
Next
foreach語句是列舉值周圍的包裝函式，它只允許讀取集合，而不是寫入集合。
建構函式
| HybridDictionary() |
建立空的、區分大小寫的 HybridDictionary。 |
| HybridDictionary(Boolean) |
建立具有指定大小寫區分的空 HybridDictionary。 |
| HybridDictionary(Int32) |
建立具有指定初始大小的大小寫區分之 HybridDictionary。 |
| HybridDictionary(Int32, Boolean) |
建立具有指定初始大小和大小寫區分的 HybridDictionary。 |
屬性
| Count |
取得 HybridDictionary 中所包含的索引鍵/值組數目。 |
| IsFixedSize |
取得值，指出 HybridDictionary 是否有固定的大小。 |
| IsReadOnly |
取得值，指出 HybridDictionary 是否唯讀。 |
| IsSynchronized |
取得值，指出 HybridDictionary 是否為同步 (安全執行緒)。 |
| Item[Object] |
取得或設定與指定之索引鍵相關聯的值。 |
| Keys |
取得含有 ICollection 中的索引鍵的 HybridDictionary。 |
| SyncRoot |
取得可用以同步存取 HybridDictionary 的物件。 |
| Values |
取得 ICollection，包含 HybridDictionary 中的值。 |
方法
| Add(Object, Object) |
將有指定索引鍵和數值項目加入 HybridDictionary 中。 |
| Clear() |
移除 HybridDictionary 的所有項目。 |
| Contains(Object) |
判斷 HybridDictionary 是否包含特定索引鍵。 |
| CopyTo(Array, Int32) |
將 HybridDictionary 項目複製到一維 Array 執行個體的指定索引處。 |
| Equals(Object) |
判斷指定的物件是否等於目前的物件。 (繼承來源 Object) |
| GetEnumerator() |
傳回透過 IDictionaryEnumerator 重複的 HybridDictionary。 |
| 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) |
將有指定索引鍵的項目從 HybridDictionary 移除。 |
| 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() |
傳回透過 IEnumerator 重複的 HybridDictionary。 |
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) |

執行緒安全性
Visual Basic 中的公用靜態 (Shared) 此類型的成員是安全線程。 並非所有的執行個體成員都是安全執行緒。
此實作不提供的同步處理 (線程安全) 包裝HybridDictionary函式，但衍生類別可以使用 屬性建立自己的同步版本HybridDictionarySyncRoot。
透過集合進行列舉在本質上並非安全執行緒程序。 即使集合經過同步化，其他的執行緒仍可修改該集合，使列舉值擲回例外狀況。 若要保證列舉過程的執行緒安全，您可以在整個列舉過程中鎖定集合，或攔截由其他執行緒的變更所造成的例外狀況。
