Utilice este método para crear un Process componente nuevo y asociarlo a un recurso de proceso en el equipo local.Use this method to create a new Process component and associate it with a process resource on the local computer. El recurso de proceso ya debe existir en el equipo, ya que no GetProcessById(Int32) crea un recurso del sistema, sino que asocia un recurso a un componente generado por la aplicación Process .The process resource must already exist on the computer, because GetProcessById(Int32) does not create a system resource, but rather associates a resource with an application-generated Process component. Un proceso Id solo se puede recuperar para un proceso que se está ejecutando actualmente en el equipo.A process Id can be retrieved only for a process that is currently running on the computer. Una vez finalizado el proceso, GetProcessById(Int32) se produce una excepción si se pasa un identificador expirado.After the process terminates, GetProcessById(Int32) throws an exception if you pass it an expired identifier.

En un equipo determinado, el identificador de un proceso es único.On any particular computer, the identifier of a process is unique. GetProcessById(Int32) Devuelve un proceso como máximo.GetProcessById(Int32) returns one process at most. Si desea obtener todos los procesos que ejecutan una aplicación determinada, use GetProcessesByName(String) .If you want to get all the processes running a particular application, use GetProcessesByName(String). Si existen varios procesos en el equipo que ejecuta la aplicación especificada, GetProcessesByName(String) devuelve una matriz que contiene todos los procesos asociados.If multiple processes exist on the computer running the specified application, GetProcessesByName(String) returns an array containing all the associated processes. Puede consultar cada uno de estos procesos a su vez para su identificador.You can query each of these processes in turn for its identifier. El identificador de proceso se puede ver en el Processes panel del administrador de tareas de Windows.The process identifier can be viewed in the Processes panel of the Windows Task Manager. La PID columna muestra el identificador de proceso que se asigna a un proceso.The PID column displays the process identifier that is assigned to a process.

El processId parámetro es Int32 (un entero con signo de 32 bits), aunque la API de Windows subyacente usa un DWORD (un entero de 32 bits sin signo) para API similares.The processId parameter is an Int32 (a 32-bit signed integer), although the underlying Windows API uses a DWORD (an unsigned 32-bit integer) for similar APIs. Esto es así por motivos históricos.This is for historical reasons.
