Winform开机启动与托盘显示

近段时间忙于写一个winform小程序，对于擅长写web程序的我谈不上是在分享，这里所写的相当于我的备忘录，呵呵。。
1)开机启动

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("MT128Stock", 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("MT128Stock", false);
R_run.Close();
R_local.Close();
}
catch (Exception ex)
{
MessageBox.Show("您需要管理員權權限修改", "提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
throw;
}

}

2)托盘显示
向winfom中插入NotifyIcon控件notifyIcon1

protected override void OnSizeChanged(EventArgs e)
{

if (this.WindowState == FormWindowState.Normal)
{
this.Width = 920;
this.Height = 530;
}

base.OnSizeChanged(e);
}
protected override void OnClosing(CancelEventArgs e)
{
//base.OnClosing(e);
e.Cancel = true;

HideMainForm();

}
private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{
if (this.Visible)
{
HideMainForm();
}
else
{
ShowMainForm();
}

}
private void HideMainForm()
{
this.Hide();
}

private void ShowMainForm()
{
this.WindowState = FormWindowState.Normal;
this.Show();
this.Activate();
}

private void ExitMainForm()
{
if (MessageBox.Show("您確認要退出股票接收程序嗎？", "確認退出", MessageBoxButtons.OKCancel, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2) == DialogResult.OK)
{
this.notifyIcon1.Visible = false;
this.Close();
this.Dispose();
Application.Exit();
}
}

3)托盘显示的右击菜单
向winfom中插入ContextMenuStrip控件contextMenuStrip1，再将notifyIcon1的ContextMenuStrip属性值设为contextMenuStrip1,并添加多项相关Items

#region 右键菜单处理，显示　隐藏　退出
private void MinShowItem_Click(object sender, EventArgs e)
{
HideMainForm();

}

private void ShowItem_Click(object sender, EventArgs e)
{
ShowMainForm();
}

private void ExitItem_Click(object sender, EventArgs e)
{
ExitMainForm();
}

#endregion
