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 static Process[] GetProcesses()

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.

The following example retrieves information of the current process, all instances of Notepad running on the local computer, all instances of Notepad running on a specific computer using the computer alias and an IP address, all processes running on the local computer and a remote computer, a specific process on the local computer or a remote computer using the process id.

using System;
using System.Diagnostics;
using System.ComponentModel;

namespace MyProcessSample
{
	/// <summary> 
	/// Shell for the sample. 
	/// </summary> 
	class MyProcess
	{
		
	   
		
		void BindToRunningProcesses()
		{
			// Get the current process.
			Process currentProcess = Process.GetCurrentProcess();

			
			// Get all instances of Notepad running on the local 
			// computer.
			Process [] localByName = Process.GetProcessesByName("notepad");

			
			// Get all instances of Notepad running on the specifiec 
			// computer. 
			// 1. Using the computer alias (do not precede with "\\").
			Process [] remoteByName = Process.GetProcessesByName("notepad", "myComputer");
			
			// 2. Using an IP address to specify the machineName parameter. 
			Process [] ipByName = Process.GetProcessesByName("notepad", "169.0.0.0");
			
			
			// Get all processes running on the local computer.
			Process [] localAll = Process.GetProcesses();

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

			
			// Get a process on the local computer, using the process id.
			Process localById = Process.GetProcessById(1234);

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