StackFrame (Clase)

Proporciona información sobre StackFrame, que representa una llamada a una función en la pila de llamadas del subproceso actual.

public class StackFrame

StackFrame se crea y se inserta en la pila de llamadas de todas las llamadas a funciones realizadas durante la ejecución de un subproceso. El marco de pila siempre incluye información sobre MethodBase y también puede incluir información sobre el nombre de archivo, el número de línea y el número de columna.

La información de StackFrame será más descriptiva con configuraciones de versiones de depuración. Las versiones de depuración incluyen símbolos de depuración de forma predeterminada; sin embargo, las versiones de lanzamiento no incluyen estos símbolos. Los símbolos de depuración contienen la mayor parte de la información de archivo, nombre de método, número de línea y columna que se utiliza para construir objetos StackFrame.

En el siguiente ejemplo de código se muestra la forma de crear y utilizar StackFrame.
