Comentarios

CompilerError representa un error del compilador o una advertencia devuelta por el compilador.

Nota

Esta clase contiene una demanda de herencia en el nivel de clase que se aplica a todos los miembros. Se SecurityException produce una excepción cuando la clase derivada no tiene permiso de plena confianza. Para más información sobre las demandas de herencia, consulte Demandas de herencia.

Constructores

CompilerError()	Inicializa una nueva instancia de la clase CompilerError.
CompilerError(String, Int32, Int32, String, String)	Inicializa una nueva instancia de la clase CompilerError que utiliza el nombre de archivo, línea, columna, número de error y texto de error especificados.

Propiedades

Column	Obtiene o establece el número de columna donde se produce el origen del error.
ErrorNumber	Obtiene o establece el número de error.
ErrorText	Obtiene o establece el texto del mensaje de error.
FileName	Obtiene o establece el nombre del archivo de código fuente que contiene el código que provocó el error.
IsWarning	Obtiene o establece un valor que indica si el error es una advertencia.
Line	Obtiene o establece el número de línea donde se produce el origen del error.

Métodos

Equals(Object)	Determina si el objeto especificado es igual que el objeto actual. (Heredado de Object)
GetHashCode()	Sirve como la función hash predeterminada. (Heredado de Object)
GetType()	Obtiene el Type de la instancia actual. (Heredado de Object)
MemberwiseClone()	Crea una copia superficial del Object actual. (Heredado de Object)
ToString()	Proporciona una implementación del método ToString() de Object.
