StackOverflowException クラス

保留状態のメソッド呼び出しが多くなりすぎ、実行スタックがオーバーフローした場合にスローされる例外。このクラスは継承できません。

スレッドセーフ

この型の public static (Visual Basicでは Shared) のすべてのメンバは、マルチスレッド操作で安全に使用できます。インスタンスのメンバの場合は、スレッドセーフであるとは限りません。

解説

StackOverflowException は、再帰の回数がかなり多い場合や無限に続く場合などに生じる、実行スタックのオーバーフローによるエラーに対してスローされます。

MSIL (Microsoft Intermediate Language) の Localloc 命令は、 StackOverflowException をスローします。

StackOverflowException は、値 0x800703E9 を保持する HRESULT COR_E_STACKOVERFLOW を使用します。

StackOverflowException のインスタンスの初期プロパティ値の一覧については、 StackOverflowException コンストラクタのトピックを参照してください。
