Comentarios

Use la Environment clase para recuperar información como argumentos de línea de comandos, el código de salida, la configuración de variables de entorno, el contenido de la pila de llamadas, la hora desde el último arranque del sistema y la versión de Common Language Runtime.

Propiedades

CommandLine	Obtiene la línea de comandos para este proceso.
CpuUsage	Proporciona información acerca del entorno y la plataforma actuales, y la forma de manipularlos. Esta clase no puede heredarse.
CurrentDirectory	Obtiene o establece la ruta de acceso completa del directorio de trabajo actual.
CurrentManagedThreadId	Obtiene un identificador único para el actual subproceso administrado.
ExitCode	Obtiene o establece el código de salida del proceso.
HasShutdownStarted	Obtiene un valor que indica si el dominio de aplicación actual se está descargando o si Common Language Runtime (CLR) se está cerrando.
Is64BitOperatingSystem	Permite obtener un valor que indica si el sistema operativo actual es de 64 bits.
Is64BitProcess	Permite obtener un valor que indica si el proceso actual es de 64 bits.
IsPrivilegedProcess	Obtiene un valor que indica si el proceso actual está autorizado para realizar funciones relevantes para la seguridad.
MachineName	Obtiene el nombre NetBIOS del equipo local.
NewLine	Obtiene la cadena de nueva línea definida para este entorno.
OSVersion	Permite obtener el identificador y el número de versión de la plataforma actual.
ProcessId	Obtiene el identificador único del proceso actual.
ProcessorCount	Obtiene el número de procesadores disponibles para el proceso actual.
ProcessPath	Devuelve la ruta de acceso del archivo ejecutable que inició el proceso que se está ejecutando actualmente. Devuelve `null` cuando la ruta de acceso no está disponible.
StackTrace	Obtiene información de seguimiento de la pila actual.
SystemDirectory	Obtiene la ruta de acceso completa del directorio del sistema.
SystemPageSize	Obtiene el número de bytes de la página de memoria del sistema operativo.
TickCount	Obtiene el número de milisegundos transcurridos desde que se inició el sistema.
TickCount64	Obtiene el número de milisegundos transcurridos desde que se inició el sistema.
UserDomainName	Obtiene el nombre de dominio de red asociado al usuario actual.
UserInteractive	Obtiene un valor que indica si el proceso actual se ejecuta en modo de interacción con el usuario.
UserName	Obtiene el nombre de la persona asociada al subproceso actual.
Version	Permite obtener una versión que consiste en los números principal, secundario, de compilación y de revisión de Common Language Runtime.
WorkingSet	Obtiene la cantidad de memoria física asignada al contexto del proceso.

Métodos

Exit(Int32)	Termina este proceso y devuelve un código de salida al sistema operativo.
ExpandEnvironmentVariables(String)	Reemplaza el nombre de cada variable de entorno incluida en la cadena especificada por la cadena equivalente del valor de la variable y devuelve la cadena resultante.
FailFast(String)	Finaliza inmediatamente el proceso antes de notificar un mensaje de error. Para Windows, el mensaje de error se escribe en el registro de eventos de aplicación de Windows y el mensaje se incluye en la notificación de errores a Microsoft. En el caso de los sistemas similares a Unix, el mensaje, junto con el seguimiento de la pila, se escribe en el flujo de error estándar.
FailFast(String, Exception)	Finaliza inmediatamente el proceso antes de notificar un mensaje de error. Para Windows, el mensaje de error se escribe en el registro de eventos de aplicación de Windows y la información de mensaje y excepción se incluye en los informes de errores a Microsoft. En el caso de los sistemas similares a Unix, el mensaje junto con el seguimiento de la pila se escribe en el flujo de error estándar.
GetCommandLineArgs()	Devuelve una matriz de cadena que contiene los argumentos de la línea de comandos del proceso actual.
GetEnvironmentVariable(String)	Recupera el valor de una variable de entorno del proceso actual.
GetEnvironmentVariable(String, EnvironmentVariableTarget)	Recupera el valor de una variable de entorno del proceso actual o de la clave del Registro del sistema operativo Windows para la máquina local o el usuario actual.
GetEnvironmentVariables()	Recupera todos los nombres de las variables de entorno y sus valores del proceso actual.
GetEnvironmentVariables(EnvironmentVariableTarget)	Recupera todos los nombres de las variables de entorno y sus valores del proceso actual o de la clave del Registro del sistema operativo Windows para la máquina local o el usuario actual.
GetFolderPath(Environment+SpecialFolder)	Obtiene la ruta de acceso a la carpeta especial del sistema especificada.
GetFolderPath(Environment+SpecialFolder, Environment+SpecialFolderOption)	Obtiene la ruta de acceso a la carpeta especial del sistema especificada mediante una opción especificada para acceder a carpetas especiales.
GetLogicalDrives()	Devuelve una matriz de cadena que contiene los nombres de las unidades lógicas del equipo actual.
SetEnvironmentVariable(String, String)	Crea, modifica o elimina una variable de entorno almacenada en el proceso actual.
SetEnvironmentVariable(String, String, EnvironmentVariableTarget)	Crea, modifica o elimina una variable de entorno almacenada en el proceso actual o en la clave del Registro del sistema operativo Windows reservada para la máquina local o el usuario actual.
