【C#】C#+Winform 實現切換用戶功能

方法一和方法二均爲退出主進程後，重新開啓新進程。方法三爲不退出主進程，將窗體隱藏，切換用戶時，重新新建一個窗體。被隱藏的窗體與新建的窗體同在一個線程下。

方法一：

 

#region 登錄部分
private void RtnLoginOK_Click(object sender, EventArgs e)	//登錄按鈕單擊事件
{
	this.Hide();
	FrmRoutineMain formRtnLoginOK = new FrmRoutineMain();	//新建主窗體
	formRtnLoginOK.ShowDialog();
}
#endregion

#region 切換用戶
private void RtnMainSwitchUser_Click(object sender, EventArgs e)	//切換用戶按鈕單擊事件
{
	if (DialogResult.Yes == MessageBox.Show("您確定要退出登陸嗎？", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question))
	{
		System.Diagnostics.Process.Start(System.Reflection.Assembly.GetExecutingAssembly().Location, "+自己程序設置的啓動參數，沒有則省略");
		Process.GetCurrentProcess().Kill();
	}
}
#endregion	//登錄按鈕單擊事件
{
	this.Hide();
	FrmRoutineMain formRtnLoginOK = new FrmRoutineMain();	//新建主窗體
	formRtnLoginOK.ShowDialog();
}
#endregion

#region 切換用戶
private void RtnMainSwitchUser_Click(object sender, EventArgs e)	//切換用戶按鈕單擊事件
{
	if (DialogResult.Yes == MessageBox.Show("您確定要退出登陸嗎？", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question))
