注釈

StackFrame は、スレッドの実行中に行われたすべての関数呼び出しに対して作成され、呼び出し履歴にプッシュされます。A StackFrame is created and pushed on the call stack for every function call made during the execution of a thread. スタックフレームには常に MethodBase 情報が含まれており、必要に応じてファイル名、行番号、および列番号の情報を含めることができます。The stack frame always includes MethodBase information, and optionally includes file name, line number, and column number information.

StackFrame 情報は、デバッグビルド構成で最も有益です。StackFrame information will be most informative with Debug build configurations. 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。By default, Debug builds include debug symbols, while Release builds do not. デバッグシンボルには、StackFrame オブジェクトの構築に使用されるファイル、メソッド名、行番号、および列情報の大部分が含まれています。The debug symbols contain most of the file, method name, line number, and column information used in constructing StackFrame objects.

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。Initializes a new instance of the StackFrame class.

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。Initializes a new instance of the StackFrame class, optionally capturing source information.

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。Initializes a new instance of the StackFrame class that corresponds to a frame above the current stack frame.

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。Initializes a new instance of the StackFrame class that corresponds to a frame above the current stack frame, optionally capturing source information.

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。Initializes a new instance of the StackFrame class that contains only the given file name and line number.

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。Initializes a new instance of the StackFrame class that contains only the given file name, line number, and column number.

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。Defines the value that is returned from the GetNativeOffset() or GetILOffset() method when the native or Microsoft intermediate language (MSIL) offset is unknown. このフィールドは定数です。This field is constant.

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定します。Determines whether the specified object is equal to the current object.

(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。Gets the column number in the file that contains the code that is executing. 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。This information is typically extracted from the debugging symbols for the executable.

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。Gets the line number in the file that contains the code that is executing. 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。This information is typically extracted from the debugging symbols for the executable.

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。Gets the file name that contains the code that is executing. 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。This information is typically extracted from the debugging symbols for the executable.

GetHashCode()

既定のハッシュ関数として機能します。Serves as the default hash function.

(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。Gets the offset from the start of the Microsoft intermediate language (MSIL) code for the method that is executing. 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。This offset might be an approximation depending on whether or not the just-in-time (JIT) compiler is generating debugging code. このデバッグ情報の生成は、DebuggableAttribute により制御されます。The generation of this debugging information is controlled by the DebuggableAttribute.

GetMethod()

フレームを実行しているメソッドを取得します。Gets the method in which the frame is executing.

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。Gets the offset from the start of the native just-in-time (JIT)-compiled code for the method that is being executed. 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。The generation of this debugging information is controlled by the DebuggableAttribute class.

GetType()

現在のインスタンスの Type を取得します。Gets the Type of the current instance.

(継承元 Object)
MemberwiseClone()

現在の Object の簡易コピーを作成します。Creates a shallow copy of the current Object.

(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。Builds a readable representation of the stack trace.

拡張メソッド

GetNativeImageBase(StackFrame)
