前言

因 为数据库在做MVC版的养老保险系统时就已经做好了,所以这里直接用以前的,就不再重新做数据库了

言归正传,
因为MVC版的养老系统配色风格过于古老,所以这里我大胆的使用紫色为主的冷色调主题

首先是登入界面的前端实现好的样式

思路

使用的Grid布局,将这个窗体一分为二
然后再在Grid布局分割的两个区域内分别嵌套了一个border容器
这个容器主要的作用是为了实现窗体的圆角
因为退出登入的按钮位置已经放置了两个单选框
所以我就把左边整个紫色部分做成了退出登入按钮

注意: 要想让窗体没有窗体自带的哪些边框之类的
记得设置

WindowStyle=“None”
WindowStartupLocation=“CenterScreen”
Background=“Transparent”
AllowsTransparency=“True”

下面是XAML视图代码,
因为后台代码已经写了完整的注释了,所以这里就不在累述了

        public Login()
        {
            InitializeComponent();
            JiaZai();
            //左边紫色页面鼠标左键键摁下事件
            border_ZiSe.MouseLeftButtonDown += MyPublicLibrary.UtilityRelated.UtilityOff;

        }

        private void Hello()
        {
           
        }

        private void Button_DengRu_Click(object sender, RoutedEventArgs e)
        {
            var loginTime = DateTime.Now;
            var jobNumberId = textBox_JobNumber.Text.Trim();
            var yuanGongMm = passwordBox_Password.Password.Trim();
            //FangJianZhuangTaiData();
            //byte intUserType = Convert.ToByte(comboBoxZhuangTaiChaXun.SelectedIndex);//输出索引
            //string intUserTypes =Convert.ToString( comboBoxZhuangTaiChaXun.SelectedItem);//输出一个object.里面包含绑定的list

             此时的 myComboxBox.SelectedValue = System.Windows.Controls.ComboBoxItem: 选项的内容
             所以如果用SelectedValue这种方法获取选中的值，还需要切割字符串

                        int comboBoxAreaId = ((dynamic)comboBox_AreaID.SelectedItem).id;
                        try
                        {
                            //查询员工号是否输入正确,当员工号输入正确时,返回该员工数据,
                            var tbUser = (from dbUser in myModels.S_User
