Publicado: octubre de 2016

Crea un nuevo componente Process para cada recurso de proceso del equipo local.

Espacio de nombres:   System.Diagnostics
Ensamblado:  System (en System.dll)

public static Process[] GetProcesses()

Valor devuelto

Type: System.Diagnostics.Process[]

Matriz de tipo Process que representa todos los recursos del proceso que se ejecutan en el equipo local.

Use this method to create an array of new T:System.Diagnostics.Process components and associate them with all the process resources on the local computer. The process resources must already exist on the local computer, because M:System.Diagnostics.Process.GetProcesses does not create system resources but rather associates resources with application-generated T:System.Diagnostics.Process components. Because the operating system itself is running background processes, this array is never empty.

If you do not want to retrieve all the processes running on the computer, you can restrict their number by using the M:System.Diagnostics.Process.GetProcessById(System.Int32,System.String) or M:System.Diagnostics.Process.GetProcessesByName(System.String) method. M:System.Diagnostics.Process.GetProcessById(System.Int32,System.String) creates a T:System.Diagnostics.Process component that is associated with the process identified on the system by the process identifier that you pass to the method. M:System.Diagnostics.Process.GetProcessesByName(System.String) creates an array of T:System.Diagnostics.Process components whose associated process resources share the executable file you pass to the method.

System_CAPS_noteNota

Multiple Windows services can be loaded within the same instance of the Service Host process (svchost.exe). GetProcesses does not identify those individual services; for that, see M:System.ServiceProcess.ServiceController.GetServices.

The following example retrieves information of the current process, processes running on the local computer, all instances of Notepad running on the local computer, and a specific process on the local computer. It then retrieves information for the same processes on a remote computer.

namespace MyProcessSample
{
    class MyProcess
    {
        void BindToRunningProcesses()
        {
            // Get the current process.
            Process currentProcess = Process.GetCurrentProcess();

            // Get all processes running on the local computer.
            Process[] localAll = Process.GetProcesses();

            // Get all instances of Notepad running on the local computer.
            // This will return an empty array if notepad isn't running.
            Process[] localByName = Process.GetProcessesByName("notepad");

            // Get a process on the local computer, using the process id.
            // This will throw an exception if there is no such process.
            Process localById = Process.GetProcessById(1234);


            // Get processes running on a remote computer. Note that this
            // and all the following calls will timeout and throw an exception
            // if "myComputer" and 169.0.0.0 do not exist on your local network.

            // Get all processes on a remote computer.
            Process[] remoteAll = Process.GetProcesses("myComputer");

            // Get all instances of Notepad running on the specific computer, using machine name.
            Process[] remoteByName = Process.GetProcessesByName("notepad", "myComputer");

            // Get all instances of Notepad running on the specific computer, using IP address.
            Process[] ipByName = Process.GetProcessesByName("notepad", "169.0.0.0");

            // Get a process on a remote computer, using the process id and machine name.
            Process remoteById = Process.GetProcessById(2345, "myComputer");
        }

        static void Main()
        {
            MyProcess myProcess = new MyProcess();
            myProcess.BindToRunningProcesses();
        }
    }
}
