Комментарии

StackFrame Создается и помещается в стек вызовов для каждого вызова функции, сделанного во время выполнения потока.A StackFrame is created and pushed on the call stack for every function call made during the execution of a thread. Кадр стека всегда содержит MethodBase сведения и при необходимости включает в себя имя файла, номер строки и сведения о номере столбца.The stack frame always includes MethodBase information, and optionally includes file name, line number, and column number information.

StackFrameинформация будет наиболее информативной с отладочными конфигурациями сборки.StackFrame information will be most informative with Debug build configurations. По умолчанию отладочные сборки содержат отладочные символы, а сборки выпуска — нет.By default, Debug builds include debug symbols, while Release builds do not. Отладочные символы содержат большую часть сведений о файле, имени метода, номере строки и столбцах, используемых при построении StackFrame объектов.The debug symbols contain most of the file, method name, line number, and column information used in constructing StackFrame objects.

Поля

OFFSET_UNKNOWN OFFSET_UNKNOWN OFFSET_UNKNOWN OFFSET_UNKNOWN

Определяет значение, возвращаемое методом GetNativeOffset(), или GetILOffset(), если смещение в исходном коде или коде на языке MSIL неизвестно.Defines the value that is returned from the GetNativeOffset() or GetILOffset() method when the native or Microsoft intermediate language (MSIL) offset is unknown. Это поле является константой.This field is constant.

Методы

Equals(Object) Equals(Object) Equals(Object) Equals(Object)

Определяет, равен ли заданный объект текущему объекту.Determines whether the specified object is equal to the current object.

(Inherited from Object)
GetFileColumnNumber() GetFileColumnNumber() GetFileColumnNumber() GetFileColumnNumber()

Получает номер столбца в файле, содержащем выполняемый код.Gets the column number in the file that contains the code that is executing. Эти сведения обычно извлекаются из символов отладки для исполняемого файла.This information is typically extracted from the debugging symbols for the executable.

GetFileLineNumber() GetFileLineNumber() GetFileLineNumber() GetFileLineNumber()

Получает номер строки в файле, содержащем выполняемый код.Gets the line number in the file that contains the code that is executing. Эти сведения обычно извлекаются из символов отладки для исполняемого файла.This information is typically extracted from the debugging symbols for the executable.

GetFileName() GetFileName() GetFileName() GetFileName()

Получает имя файла, содержащего выполняемый код.Gets the file name that contains the code that is executing. Эти сведения обычно извлекаются из символов отладки для исполняемого файла.This information is typically extracted from the debugging symbols for the executable.

GetHashCode() GetHashCode() GetHashCode() GetHashCode()

Служит хэш-функцией по умолчанию.Serves as the default hash function.

(Inherited from Object)
GetILOffset() GetILOffset() GetILOffset() GetILOffset()

Получает смещение от начала кода на языке MSIL для выполняемого метода.Gets the offset from the start of the Microsoft intermediate language (MSIL) code for the method that is executing. Это смещение может быть приблизительным, в зависимости от того, создает ли JIT-компилятор код отладки.This offset might be an approximation depending on whether or not the just-in-time (JIT) compiler is generating debugging code. Управление созданием этих сведений отладки осуществляется классом DebuggableAttribute.The generation of this debugging information is controlled by the DebuggableAttribute.

GetMethod() GetMethod() GetMethod() GetMethod()

Получает метод, в котором выполняется кадр.Gets the method in which the frame is executing.

GetNativeOffset() GetNativeOffset() GetNativeOffset() GetNativeOffset()

Получает смещение от начала исходного, скомпилированного JIT-компилятором кода для исполняемого метода.Gets the offset from the start of the native just-in-time (JIT)-compiled code for the method that is being executed. Управление созданием этих сведений отладки осуществляется классом DebuggableAttribute.The generation of this debugging information is controlled by the DebuggableAttribute class.

GetType() GetType() GetType() GetType()

Возвращает объект Type для текущего экземпляра.Gets the Type of the current instance.

(Inherited from Object)
MemberwiseClone() MemberwiseClone() MemberwiseClone() MemberwiseClone()
