How to make task manager in c#. Net.

You can use the System.Diagnostics.Process classes for getting the information about processes running in the computer system. To start new process you can use System.Diagnostics.Process.Start(ProcessnameOrFilename); and to end a process you can Process.Kill()  use  function.

 Codes:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.Diagnostics;

namespace WindowsFormsApplication1

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

//to start new process

        private void button1_Click(object sender, EventArgs e)

        {

            openFileDialog1.ShowDialog();

            try

            {

                                           System.Diagnostics.Process.Start(openFileDialog1.FileName); Form1_Load(sender, e);

            }

            catch

            {

            }         

        }

//to end a process

        private void button2_Click(object sender, EventArgs e)

        {

         

            foreach (Process p in System.Diagnostics.Process.GetProcesses())

            {

                try

                {

                    if (p.ProcessName.ToString() == listBox1.SelectedItem.ToString())

                    {

                        p.Kill();

                    }

                }

                catch

                {

                }

            }

        }

//to add process in listbox control

        private void Form1_Load(object sender, EventArgs e)

        {

            foreach (Process p in System.Diagnostics.Process.GetProcesses())

            {

                listBox1.Items.Add(p.ProcessName);

            }

          

        }

   //timer for refreshing current process

        private void timer1_Tick(object sender, EventArgs e)

        {

        listBox1.Items.Clear();

            foreach (Process p in                        System.Diagnostics.Process.GetProcesses())

            {

                listBox1.Items.Add(p.ProcessName);

            }

        }

    }

}
