简答的登录模块：

        private void signIn_Click(object sender, RoutedEventArgs e)
        {
            int i = 0;
            string str = signIn.Content.ToString();
            if (textBox1.Text.ToString() == "" && str == "登陆")
            {
                System.Windows.Forms.MessageBox.Show("登陆错误");
                i = 0;
            }
            else
            {
                i =1;
                if (str == "登陆" && i == 1)
                {
                    textBox1.Visibility = Visibility.Hidden;
                    passwordBox1.Visibility = Visibility.Hidden;
                    textBlock2.Visibility = Visibility.Visible;
                    textBlock2.Text = "欢迎用户  "+textBox1.Text;
                    textBox1.Text = null;
                    signIn.Content = "退出";
                }
                else
                {
                    textBlock2.Text = null;
                    passwordBox1.Password = null;
                    textBox1.Visibility = Visibility.Visible;
                    passwordBox1.Visibility = Visibility.Visible;
                    textBlock2.Visibility = Visibility.Hidden;
                    textBlock2.Text = textBox1.Text;
                    signIn.Content = "登陆";

                }
