CollectionBase.GetEnumerator メソッド

CollectionBase インスタンスを反復処理する列挙子を返します。

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

Visual Basic (宣言)

Public Function GetEnumerator As
 IEnumerator

Visual Basic (使用法)

Dim instance As CollectionBase
Dim returnValue As IEnumerator

returnValue = instance.GetEnumerator

public IEnumerator GetEnumerator ()

C++

public:
virtual IEnumerator^ GetEnumerator () sealed

public final IEnumerator GetEnumerator ()

JScript

public final function GetEnumerator () : IEnumerator

戻り値
CollectionBase インスタンスの IEnumerator。

解説

C# 言語の foreach ステートメント (Visual Basic の場合は for each) を使用することで列挙子の複雑さを回避できます。したがって、列挙子を直接操作するのではなく、foreach の使用をお勧めします。

列挙子を使用すると、コレクション内のデータを読み取ることができますが、基になるコレクションを変更することはできません。

初期状態では、列挙子はコレクションの最初の要素の前に位置しています。Reset を実行した場合も、列挙子はこの位置に戻されます。この位置で Current を呼び出すと、例外がスローされます。したがって、Current の値を読み取る前に、MoveNext を呼び出して、コレクションの最初の要素に列挙子を進める必要があります。

Current は、MoveNext または Reset が呼び出されるまでは同じオブジェクトを返します。MoveNext は、Current を次の要素に設定します。

MoveNext がコレクションの末尾を過ぎると、列挙子はコレクションの最後の要素の後ろに配置され、MoveNext は false を返します。列挙子がこの位置にある場合、以降、MoveNext を呼び出しても false が返されます。MoveNext への最後の呼び出しで false が返された場合に、Current を呼び出すと例外がスローされます。Current をコレクションの最初の要素に再び設定するには、Reset を呼び出してから、MoveNext を呼び出します。

列挙子は、コレクションが変更されない限り有効です。要素の追加、変更、削除などの変更がコレクションに対して実行されると、列挙子は回復不可能な無効状態になり、次に MoveNext または Reset を呼び出すと InvalidOperationException がスローされます。MoveNext と Current の間でコレクションを変更すると、列挙子が無効になっている場合でも、Current が設定先の要素を返します。

列挙子には、コレクションへの排他的なアクセスがありません。したがって、コレクションの列挙処理は、本質的にはスレッドセーフな処理ではありません。コレクションが同期されている場合でも、他のスレッドがそのコレクションを変更する可能性はあり、そのような状況が発生すると列挙子は例外をスローします。列挙処理を確実にスレッドセーフに行うには、列挙中にコレクションをロックするか、他のスレッドによって行われた変更によってスローされる例外をキャッチします。

GetEnumerator メソッドは、既定では COM クライアントから参照できませんが、CollectionBase クラスを継承することにより公開され、COM クライアントの不適切な動作の原因となる場合があります。

このメソッドは O(1) 操作です。
