c/s项目记住账号密码功能

 
1.login.cs中的一开始加载页面
//从注册表中读取 是否保存了用户名密码 自动启动配置
            string RegeditKey = "PMSApp";
            RegistryKey location = Registry.LocalMachine;
            RegistryKey soft = location.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall", false);//可写 
            RegistryKey myPass = soft.OpenSubKey(RegeditKey, false);
            try
            {
                string banben = myPass.GetValue("DisplayVersion").ToString();
                lbbanben.Text = "版本号 : " + banben;
            }
            catch (Exception ex)
            {
                //MessageBox.Show(ex.Message);
            }
            try
            {
                string s1 = myPass.GetValue("s1").ToString();//s1账号
                string s2 = myPass.GetValue("s2").ToString();//s2密码

                bool ifSave = Convert.ToBoolean(myPass.GetValue("s3"));//s3判断状态，是否需要启动改功能
                checkBox1.IsChecked = ifSave;


                if (ifSave)
                {
                    txtAdminPassword.Password = "";//我只需要记住账号所以这个地方可以忽略
                    txtAdminName.Text = s1;
                }
                else
                {
                    txtAdminPassword.Password = "";
                    txtAdminName.Text = "";
                }
                //    ifFistIn = false;       //程序已启动完毕，可以执行注册表相关动作
            }
            catch (Exception ex)
            {
                //MessageBox.Show(ex.Message);
            }


2.记住账号按钮
   //记住账号
        private void checkBox1_Click(object sender, RoutedEventArgs e)
        {
            if ((sender as CheckBox).IsChecked == true)
            {
                string RegeditKey = "PMSApp";
                RegistryKey location = Registry.LocalMachine;
                RegistryKey soft = location.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall", true);//可写 
                RegistryKey myPass = soft.CreateSubKey(RegeditKey);
                myPass.SetValue("s1", txtAdminName.Text);
                myPass.SetValue("s2", txtAdminPassword.Password);
                myPass.SetValue("s3", checkBox1.IsChecked);
                soft.Close();
                location.Close();
            }
            else
            {
                string RegeditKey = "PMSApp";
                RegistryKey location = Registry.LocalMachine;
                RegistryKey soft = location.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall", true);//可写 
                RegistryKey myPass = soft.CreateSubKey(RegeditKey);
                myPass.SetValue("s1", txtAdminName.Text);
                myPass.SetValue("s2", txtAdminPassword.Password);
                myPass.SetValue("s3", checkBox1.IsChecked);
                soft.Close();
                location.Close();
            }
        }
3.更换账户时，改变记住账号的状态
 private void txtAdminName_TextChanged(object sender, TextChangedEventArgs e)
        {
            string s1 = "";
            try
            {
                string RegeditKey = "PMSApp";
                RegistryKey location = Registry.LocalMachine;
                RegistryKey soft = location.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall", false);//可写 
                RegistryKey myPass = soft.OpenSubKey(RegeditKey, false);
                s1 = myPass.GetValue("s1").ToString();
                if (txtAdminName.Text == s1)
                {
                    checkBox1.IsChecked = true;
                }
                else
                {
                    checkBox1.IsChecked = false;
                }
            }
            catch
            { }
        }
