一、了解WPF的框架结构

（第一小节随便看下就可以，简单练习就行）

1、新建WPF项目

xmlns：XML的命名空间

Margin外边距：左上右下

HorizontalAlignment：水平位置

VerticalAlignment：垂直位置

2、Border的使用

效果：

3、LoginWindow窗口

在Wpf中不是所有的标签都有Name属性，但是一定有x:Name，x:Name为了保证所有标签的唯一性

PasswordBox是密码框

winform中窗体的加载事件：Load，WPF中窗体的加载事件是Loaded

代码：

LoginWindow.xaml的代码

<Window x:Class="WpfApp1.LoginWindow"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"xmlns:local="clr-namespace:WpfApp1"mc:Ignorable="d"Title="LoginWindow" Height="450" Width="800" Loaded="Window_Loaded"><Border BorderBrush="Green" BorderThickness="3" CornerRadius="10"><!--BorderBrush:边框的颜色  BorderThickness:边框的厚度/粗细  CornerRadius:边框四个角的半径--><Grid><TextBlock HorizontalAlignment="Left" Margin="213,150,0,0" TextWrapping="Wrap" Text="账号" VerticalAlignment="Top"/><TextBlock HorizontalAlignment="Left" Margin="213,200,0,0" TextWrapping="Wrap" Text="密码" VerticalAlignment="Top" RenderTransformOrigin="-0.067,-2.57"/><TextBox Name="txtUserCount" HorizontalAlignment="Left" Height="23" Margin="306,149,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="208"/><Button  Name="btnLogin" Content="登录" HorizontalAlignment="Left" Margin="230,268,0,0" VerticalAlignment="Top" Width="75" Click="BtnLogin_Click"/><Button Name="btnClose" Content="关闭" HorizontalAlignment="Left" Margin="351,267,0,0" VerticalAlignment="Top" Width="75"/><PasswordBox x:Name="txtUserPwd" HorizontalAlignment="Left" Margin="306,200,0,0" VerticalAlignment="Top" Width="208" Height="23"/><DataGrid HorizontalAlignment="Left" Height="100" Margin="372,430,0,-115.6" VerticalAlignment="Top" Width="100"/><!--在Wpf中不是所有的标签都有Name属性，但是一定有x:Name，x:Name为了保证所有标签的唯一性--></Grid></Border>
</Window>

LoginWindow.xaml.cs的代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;namespace WpfApp1
{/// <summary>/// LoginWindow.xaml 的交互逻辑/// </summary>public partial class LoginWindow : Window{public LoginWindow(){InitializeComponent();}private void BtnLogin_Click(object sender, RoutedEventArgs e){string userAccount = txtUserCount.Text;string userPwd = txtUserPwd.Password;//this.txtUserPwd.SecurePassword;//加密字符串，保存成内存地址MainWindow mainWindow = new MainWindow();mainWindow.Show();this.Close();}/// <summary>/// 窗体加载事件/// </summary>/// <param name="sender"></param>/// <param name="e"></param>private void Window_Loaded(object sender, RoutedEventArgs e){}}
}

效果图：

4、文本框旋转

选中文本框，鼠标放到文本框的四个角的任意一个边上，然后旋转即可

默认的文本框有如下属性：

旋转后的文本框：

5、关闭主窗体，其他窗体不关

MainWindow界面:
