C#实现winform软件开机自动启动并最小化到系统托盘

一、开机自动启动：

拖一个CheckBox

1、软件启动时给CheckBox重置状态：

RegistryKey R_local = Registry.LocalMachine;
            RegistryKey R_run = R_local.CreateSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run");
            if (R_run.GetValue("BirthdayTipF") == null)
            {
                checkBox1.Checked = false;
            }
            else
            {
                checkBox1.Checked = true;
            }
            R_run.Close();
            R_local.Close();

2、CheckChanged事件：

private void checkBox1_CheckedChanged(object sender, EventArgs e)
        {
            string R_startPath = Application.ExecutablePath;
            if (checkBox1.Checked == true)
            {
                RegistryKey R_local = Registry.LocalMachine;
                RegistryKey R_run = R_local.CreateSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run");
                R_run.SetValue("BirthdayTipF", R_startPath);
                R_run.Close();
                R_local.Close();
            }
            else
            {
                try
                {
                    RegistryKey R_local = Registry.LocalMachine;
                    RegistryKey R_run = R_local.CreateSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run");
                    R_run.DeleteValue("BirthdayTipF", false);
                    R_run.Close();
                    R_local.Close();
                }
                catch (Exception ex)
                {
                    MessageBox.Show("您需要管理员权限修改", "提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
                    throw;
                }
               
            }
        }

二、最小化到系统托盘

拖一个NotifyIcon

设置form的showInTastbar属性为false

this.SizeChanged += new System.EventHandler(this.Form1_SizeChanged);

private void Form1_SizeChanged(object sender, EventArgs e)
        {
            if (this.WindowState == FormWindowState.Minimized)
            {
                this.Hide();
                this.notifyIcon1.Visible = true;
            }
        }
        private void notifyIcon1_Click(object sender, EventArgs e)
        {
            this.Visible = true;
            this.WindowState = FormWindowState.Normal;
            this.notifyIcon1.Visible = false;
        }
