String.GetEnumerator メソッド
アセンブリ: mscorlib (mscorlib.dll 内)

Dim instance As String Dim returnValue As CharEnumerator returnValue = instance.GetEnumerator
public CharEnumerator GetEnumerator ()
public: CharEnumerator^ GetEnumerator ()
public CharEnumerator GetEnumerator ()
public function GetEnumerator () : CharEnumerator
CharEnumerator オブジェクト。

IEnumerator インターフェイスでのコレクションのメンバの反復処理をサポートするプログラミング言語では、このメソッドが必要です。たとえば、Microsoft Visual Basic および C# プログラミング言語の foreach ステートメントでは、この String のインスタンス内の文字への読み取り専用アクセスを実現する CharEnumerator オブジェクトを返すために、このメソッドが呼び出されます。

GetEnumerator メソッドを使用して、入力文字列の各 System.Char を表示するコード例を次に示します。
