StackFrame Clase

Definición

Proporciona información sobre un StackFrame, que representa una llamada de función en la pila de llamadas del subproceso actual.Provides information about a StackFrame, which represents a function call on the call stack for the current thread.

Comentarios

Se crea un StackFrame y se inserta en la pila de llamadas para cada llamada de función realizada durante la ejecución de un subproceso.A StackFrame is created and pushed on the call stack for every function call made during the execution of a thread. El marco de pila siempre incluye información de MethodBase y, opcionalmente, incluye información sobre el nombre de archivo, el número de línea y el número de columna.The stack frame always includes MethodBase information, and optionally includes file name, line number, and column number information.

StackFrame información será más informativa con las configuraciones de compilación de depuración.StackFrame information will be most informative with Debug build configurations. De forma predeterminada, las compilaciones de depuración incluyen símbolos de depuración, mientras que las de versión no.By default, Debug builds include debug symbols, while Release builds do not. Los símbolos de depuración contienen la mayor parte de la información del archivo, el nombre del método, el número de línea y la columna que se usa para construir objetos StackFrame.The debug symbols contain most of the file, method name, line number, and column information used in constructing StackFrame objects.

Constructores

StackFrame()

StackFrame(Boolean)

Inicializa una nueva instancia de la clase StackFrame, mientras se inicializa la propiedad, y opcionalmente captura información de origen.Initializes a new instance of the StackFrame class, optionally capturing source information.

StackFrame(Int32)

Inicializa una nueva instancia de la clase StackFrame que corresponde a un marco situado encima del marco de pila actual.Initializes a new instance of the StackFrame class that corresponds to a frame above the current stack frame.

StackFrame(Int32, Boolean)

Inicializa una nueva instancia de la clase StackFrame que corresponde a un marco situado encima del marco de pila actual, y opcionalmente captura información de origen.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)

Inicializa una nueva instancia de la clase StackFrame que contiene únicamente el nombre de archivo y el número de línea especificados.Initializes a new instance of the StackFrame class that contains only the given file name and line number.

Campos

OFFSET_UNKNOWN

Define el valor que se devuelve desde el método GetNativeOffset() o GetILOffset() cuando se desconoce el desplazamiento nativo o de Lenguaje Intermedio de Microsoft (MSIL).Defines the value that is returned from the GetNativeOffset() or GetILOffset() method when the native or Microsoft intermediate language (MSIL) offset is unknown. Este campo es constante.This field is constant.

GetFileColumnNumber()

Obtiene el número de columna del archivo que contiene el código que se está ejecutando.Gets the column number in the file that contains the code that is executing. Esta información se extrae normalmente de los símbolos de depuración del ejecutable.This information is typically extracted from the debugging symbols for the executable.

GetFileLineNumber()

Obtiene el número de línea del archivo que contiene el código que se está ejecutando.Gets the line number in the file that contains the code that is executing. Esta información se extrae normalmente de los símbolos de depuración del ejecutable.This information is typically extracted from the debugging symbols for the executable.

GetFileName()

Obtiene el nombre de archivo que contiene el código que se está ejecutando.Gets the file name that contains the code that is executing.

GetILOffset()

Obtiene el desplazamiento desde el inicio del código del Lenguaje intermedio de Microsoft (MSIL) del método que se está ejecutando.Gets the offset from the start of the Microsoft intermediate language (MSIL) code for the method that is executing. Este desplazamiento puede ser aproximado en función de si el compilador Just-In-Time (JIT) está generando código de depuración.This offset might be an approximation depending on whether or not the just-in-time (JIT) compiler is generating debugging code. La generación de esta información de depuración está controlada por DebuggableAttribute.The generation of this debugging information is controlled by the DebuggableAttribute.

GetMethod()

Obtiene el método en el que se está ejecutando el marco.Gets the method in which the frame is executing.

GetNativeOffset()

Obtiene el desplazamiento desde el inicio del código nativo de compilación Just-In-Time (JIT) del método que se está ejecutando.Gets the offset from the start of the native just-in-time (JIT)-compiled code for the method that is being executed. La generación de esta información de depuración está controlada por la clase DebuggableAttribute.The generation of this debugging information is controlled by the DebuggableAttribute class.

GetType()

Obtiene el Type de la instancia actual.Gets the Type of the current instance.

(Heredado de Object)
MemberwiseClone()

Crea una copia superficial del Object actual.Creates a shallow copy of the current Object.

(Heredado de Object)
ToString()
