StackFrame クラス
現在のスレッドのコール スタック上での関数呼び出しを表す、 StackFrame に関する情報を提供します。

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
StackFrame は、スレッドの実行中に関数が呼び出されるたびに作成され、コール スタックにプッシュされます。スタック フレームには必ず MethodBase 情報が含まれ、オプションでファイル名、行番号、および列番号の情報も含まれます。 StackFrame 情報は、デバッグ ビルド構成と共に使用すると最も有益な情報となります。既定では、デバッグ ビルドにはデバッグ シンボルが含まれ、リリース ビルドには含まれません。デバッグ シンボルには、 StackFrame オブジェクトを構築するために使用されるファイル、メソッド名、行番号、および列情報のほとんどが含まれます。
使用例
