Process.GetProcesses Method ()

 

Creates a new Process component for each process resource on the local computer.

Namespace:   System.Diagnostics
Assembly:  System (in System.dll)

Public Shared Function GetProcesses As Process()

Return Value

Type: System.Diagnostics.Process()

An array of type Process that represents all the process resources running on the local computer.

Use this method to create an array of new 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 GetProcesses does not create system resources but rather associates resources with application-generated 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 GetProcessById or GetProcessesByName method. GetProcessById creates a Process component that is associated with the process identified on the system by the process identifier that you pass to the method. GetProcessesByName creates an array of Process components whose associated process resources share the executable file you pass to the method.

System_CAPS_noteNote

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 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.
