C Implementation Process Management Start and Stop Instances

This paper describes the starting and stopping methods of C # to realize process management. Share it for your reference. The specific implementation method is as follows:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO;
// Reference namespace 
using System.Diagnostics;
using System.Threading;
namespace StartStopProcess
{
  public partial class Form1 : Form
  {
    int fileIndex;
    string fileName = "Notepad.exe";
    Process process1 = new Process();
    public Form1()
    {
      InitializeComponent();
      // Display as a detailed list 
      listView1.View = View.Details;
      // Parameter meaning: column name, width (pixels), horizontal alignment 
      listView1.Columns.Add(" Process ID", 70, HorizontalAlignment.Left);
      listView1.Columns.Add(" Process name ", 70, HorizontalAlignment.Left);
      listView1.Columns.Add(" Occupy memory ", 70, HorizontalAlignment.Left);
      listView1.Columns.Add(" Startup time ", 70, HorizontalAlignment.Left);
      listView1.Columns.Add(" Filename ", 280, HorizontalAlignment.Left);
    }
    private void buttonStart_Click(object sender, EventArgs e)
    {
      string argument = Application.StartupPath + "\\myfile" + fileIndex + ".txt";
      if (File.Exists(argument)==false)
      {
        File.CreateText(argument);
      }
      // Set the name and parameters of the application to start 
      ProcessStartInfo ps = new ProcessStartInfo(fileName, argument);
      ps.WindowStyle = ProcessWindowStyle.Normal;
      fileIndex++;
      Process p = new Process();
      p.StartInfo = ps;
      p.Start();
      // Wait for startup to complete, otherwise getting process information may fail 
      p.WaitForInputIdle();
      RefreshListView();
    }
    private void buttonStop_Click(object sender, EventArgs e)
    {
      this.Cursor = Cursors.WaitCursor;
      // Create a new Process Array of components , And associate them with the specified process name ( Notepad ) is associated with all process resources of the .
      Process[] myprocesses;
      myprocesses = Process.GetProcessesByName(Path.GetFileNameWithoutExtension(fileName));
      foreach (Process p in myprocesses)
      {
        // The process is closed by sending a closing message to the main window of the process 
        p.CloseMainWindow();
        // Wait 1000 Milliseconds 
        Thread.Sleep(1000);
        // Release all resources associated with this component 
        p.Close();
      }
      fileIndex = 0;
      RefreshListView();
      this.Cursor = Cursors.Default;
    }
    private void RefreshListView()
    {
      listView1.Items.Clear();
      // Create Process Array of type , And associate them with all processes in the system 
      Process[] processes;
      processes = Process.GetProcessesByName(Path.GetFileNameWithoutExtension(fileName));
      foreach (Process p in processes)
      {
        // Add the process name, physical memory occupied and process start time of each process listView Medium 
        ListViewItem item = new ListViewItem(
          new string[]{
            p.Id.ToString(),
            p.ProcessName,
            string.Format("{0} KB", p.PrivateMemorySize64/1024.0f),
            string.Format("{0}",p.StartTime),
            p.MainModule.FileName
          });
        listView1.Items.Add(item);
      }
    }
    private void buttonRefresh_Click(object sender, EventArgs e)
    {
      RefreshListView();
    }
    private void Form1_Load(object sender, EventArgs e)
    {

    }
  }
}

I hope this article is helpful to everyone's C # programming.
