注釈

StackFrameは、スレッドの実行中に行われるすべての関数呼び出しについて、呼び出し履歴に作成され、プッシュされます。 スタック フレームには常に情報が含 MethodBase まれており、必要に応じてファイル名、行番号、列番号の情報が含まれます。

StackFrame 情報は、デバッグ ビルド構成で最も有益です。 既定では、デバッグ ビルドにはデバッグ シンボルが含まれますが、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、オブジェクトの構築に使用されるほとんどのファイル、メソッド名、行番号、列情報が StackFrame 含まれています。

コンストラクター

StackFrame()	StackFrame クラスの新しいインスタンスを初期化します。
StackFrame(Boolean)	StackFrame クラスの新しいインスタンスを初期化し、オプションでソース情報をキャプチャします。
StackFrame(Int32)	現在のスタック フレーム上のフレームに対応する StackFrame クラスの新しいインスタンスを初期化します。
StackFrame(Int32, Boolean)	現在のスタック フレーム上のフレームに対応する StackFrame クラスの新しいインスタンスを初期化し、オプションでソース情報をキャプチャします。
StackFrame(String, Int32)	指定されたファイル名および行番号だけを含む StackFrame クラスの新しいインスタンスを初期化します。
StackFrame(String, Int32, Int32)	指定されたファイル名、行番号、および列番号だけを含む StackFrame クラスの新しいインスタンスを初期化します。

フィールド

OFFSET_UNKNOWN

ネイティブまたは MSIL (Microsoft Intermediate Language) オフセットが不明の場合に、GetNativeOffset() メソッドまたは GetILOffset() メソッドから返される値を定義します。 このフィールドは定数です。

メソッド

Equals(Object)	指定されたオブジェクトが現在のオブジェクトと等しいかどうかを判断します。 (継承元 Object)
GetFileColumnNumber()	実行しているコードを格納しているファイルの列番号を取得します。 通常、この情報は実行可能ファイルのデバッグ シンボルから抽出されます。
GetFileLineNumber()	実行しているコードを格納しているファイルの行番号を取得します。 通常、この情報は実行可能ファイルのデバッグ シンボルから抽出されます。
GetFileName()	実行中のコードを格納しているファイル名を取得します。 通常、この情報は実行可能ファイルのデバッグ シンボルから抽出されます。
GetHashCode()	既定のハッシュ関数として機能します。 (継承元 Object)
GetILOffset()	実行中のメソッドの MSIL (Microsoft Intermediate Language) コードの先頭からのオフセットを取得します。 このオフセットは Just-In-Time (JIT) コンパイラがデバッグするコードを生成しているかどうかに依存する近似値になることがあります。 このデバッグ情報の生成は、DebuggableAttribute により制御されます。
GetMethod()	フレームを実行しているメソッドを取得します。
GetNativeOffset()	実行中のメソッドのネイティブ JIT コンパイル コードの先頭からのオフセットを取得します。 このデバッグ情報の生成は、DebuggableAttribute クラスにより制御されます。
GetType()	現在のインスタンスの Type を取得します。 (継承元 Object)
MemberwiseClone()	現在の Object の簡易コピーを作成します。 (継承元 Object)
ToString()	スタック トレースの読み取り可能な形式を構築します。

拡張メソッド

GetNativeImageBase(StackFrame)	このスタック フレームが実行しているネイティブ イメージのベース アドレスへのポインターを返します。
GetNativeIP(StackFrame)	実行されているメソッドのネイティブ コードの先頭へのインターフェイス ポインターを取得します。
HasILOffset(StackFrame)	実行中のメソッドのための IL コードの先頭からのオフセットを使用できるどうかを示します。
HasMethod(StackFrame)	指定したフレームを実行しているメソッドに関する情報があるかどうかを示します。
HasNativeImage(StackFrame)	指定したスタック フレームでネイティブ イメージが使用可能かどうかを示します。
HasSource(StackFrame)	指定したスタック フレームが実行されているコードを格納しているファイルを使用できるかどうかを示します。
