HybridDictionary コンストラクタ (Boolean)

大文字と小文字区別指定して、空の HybridDictionary作成します

名前空間: System.Collections.Specialized
アセンブリ: System (system.dll 内)
構文構文

Public Sub New ( _
    caseInsensitive As Boolean _
)
Dim caseInsensitive As Boolean

Dim instance As New HybridDictionary(caseInsensitive)
public HybridDictionary (
    bool caseInsensitive
)
public:
HybridDictionary (
    bool caseInsensitive
)
public HybridDictionary (
    boolean caseInsensitive
)
public function HybridDictionary (
    caseInsensitive : boolean
)

パラメータ

caseInsensitive

HybridDictionary で大文字小文字区別されるかどうか指定するブール値。

解説解説

caseInsensitivefalse である場合コレクションは、キーの Object.GetHashCode および Object.Equals の実装使用しますcaseInsensitivetrue である場合コレクションは、大文字と小文字区別しない単純な序数比較行います。この場合は、インバリアント カルチャについてだけ、大文字と小文字区別する規則従います。インバリアント カルチャの詳細については、System.Globalization.CultureInfo のトピック参照してください

このコンストラクタは O(1) 操作です。

caseInsensitive

HybridDictionary大文字小文字区別されるかどうか指定するブール値。

解説解説

コレクション初期サイズが ListDictionary の最適サイズより大きい場合ListDictionary から Hashtable要素コピーするオーバーヘッド避けるために、コレクションHashtable格納されます。

caseInsensitivefalse である場合コレクションは、キーの Object.GetHashCode および Object.Equals の実装使用しますcaseInsensitivetrue である場合コレクションは、大文字と小文字区別しない単純な序数比較行います。この場合は、インバリアント カルチャについてだけ、大文字と小文字区別する規則従います。インバリアント カルチャの詳細については、System.Globalization.CultureInfo のトピック参照してください

このコンストラクタは O(n) 操作です (ninitialSize)。
