Exception.StackTrace プロパティ
アセンブリ: mscorlib (mscorlib.dll 内)

Public Overridable ReadOnly Property StackTrace As String
コールスタックの先頭にある最近のメソッド呼び出しの内容を説明する文字列。

実行スタックは、指定された時点で実行されているすべてのメソッドを追跡します。メソッド呼び出しのトレースは、スタック トレースと呼ばれます。スタック トレースが出力する一覧を使用して、例外が発生するメソッド内の行番号に対する呼び出しシーケンスを追跡できます。
最適化の実行中にインライン表示などのコード変換が発生するため、StackTrace は期待されるほど多くのメソッドをレポートしない場合があります。
継承時の注意 StackTrace プロパティは、スタック トレースの内容または書式に対する制御が必要なクラスではオーバーライドされます。 既定では、スタック トレースは、例外オブジェクトがスローされる直前に取り込まれます。例外がスローされていないときに、Environment.StackTrace を使用してスタック トレース情報を取得します。
Exception をスローしてキャッチし、StackTrace プロパティを使用してスタック トレースを表示するコード例を次に示します。

_Exception.StackTrace プロパティ
アセンブリ: mscorlib (mscorlib.dll 内)

string StackTrace { get; }
コールスタックの先頭にある最近のメソッド呼び出しの内容を説明する文字列。

このメソッドは、アンマネージ コードからマネージ クラスにアクセスするためのメソッドであるため、マネージ コードからは呼び出さないでください。
Exception.StackTrace プロパティは、現在の例外がスローされたときに呼び出し履歴にあったフレームの文字列形式を取得します。
