C# Process类_进程管理器Demo

Process用于管理计算机的进程，下面给出一个C#进程管理器的DEMO。

namespace ProcessManager
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            listView1.FullRowSelect = true;
            GetProcess();
        }

        private void GetProcess()
        {
            listView1.Items.Clear();

            Process[] proList = Process.GetProcesses(".");//获得本机的进程
            lblNumber.Text = proList.Length.ToString(); //当前进程数量
            foreach (Process p in proList)
            {
                ListViewItem lvi = new ListViewItem();
                lvi.Text = p.ProcessName;
                lvi.SubItems.AddRange(new string[] { p.Id.ToString(), p.PrivateMemorySize64.ToString() }); //进程ID  使用内存
                listView1.Items.Add(lvi);
            }
        }

        private void btnStop_Click(object sender, EventArgs e)
        {
            if (listView1.SelectedItems.Count > 0)
            {
                try
                {
                    string proName = listView1.SelectedItems[0].Text;
                    Process[] p = Process.GetProcessesByName(proName); //根据进程命获得指定的进程
                    p[0].Kill(); //杀死该进程
                    MessageBox.Show("进程关闭成功！");
                    GetProcess();
                }
                catch
                {
                    MessageBox.Show("无法关闭此进程！");
                }
            }
            else
            {
                MessageBox.Show("请选择要终止的进程!");
            }
        }

        private void btnStart_Click(object sender, EventArgs e)
        {
            if (txtProcess.Text != string.Empty)
            {
                Process.Start(txtProcess.Text); //启动一个进程
            }
            else
            {
                MessageBox.Show("请输入启动项");
                txtProcess.Focus();
            }
        }
    }
}

显示如下：
