<Window x:Class="WpfApplication1.MainWindow"        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        Title="MainWindow" Height="350" Width="525">    <Grid>        <DockPanel>            <Menu DockPanel.Dock="Top">                <MenuItem Header="文件">                    <MenuItem Header="打开" Name="miOpen" Click="miOpen_Click"></MenuItem>                </MenuItem>                <MenuItem Header="编辑">                    <MenuItem Header="复制"></MenuItem>                </MenuItem>            </Menu>            <TextBox DockPanel.Dock="Bottom"></TextBox>        </DockPanel>    </Grid></Window>

<Window x:Class="WpfApplication2.MainWindow"        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        WindowState="Maximized"        Title="主程序" Height="350" Width="525">    <Grid>        <DockPanel>                        <Menu DockPanel.Dock="Top">                <MenuItem Header="打开"></MenuItem>                <MenuItem Header="编辑"></MenuItem>            </Menu>            <ToolBar DockPanel.Dock="Top" Height="30">                <Button Name="btnDelete" Click="btnDelete_Click">                    <Image Source="Images/delete.ico"></Image>                </Button>                <Button>                    <Button.Content>                        <Image Source="Images/clipboard.ico"></Image>                    </Button.Content>                </Button>                <CheckBox Content="自动保存"></CheckBox>                <TextBox></TextBox>            </ToolBar>            <TextBox Name="txtName" DockPanel.Dock="Bottom"></TextBox>        </DockPanel>            </Grid></Window>

在APP.xaml里StartupUri="MainWindow.xaml"是指定主窗口的属性

<Window x:Class="WpfApplication2.AboutWindow"        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        Title="关于" Height="500" Width="800" ResizeMode="NoResize"        WindowStartupLocation="CenterScreen" Loaded="Window_Loaded" Closed="Window_Closed">    <Grid>        <TextBox Name="txtTest" Height="23" HorizontalAlignment="Left" Margin="58,91,0,0" VerticalAlignment="Top" Width="120" Text="我的对话框" />        <PasswordBox Height="23" HorizontalAlignment="Left" Margin="69,126,0,0" Name="pwdBox1" VerticalAlignment="Top" Width="120" />    </Grid></Window>

ResizeMode="NoResize"<span style="white-space:pre"></span>使其无法修改大小

WindowStartupLocation="CenterScreen" <span style="white-space:pre"></span>窗口打开的位置在正中央

WindowState="maxsize" <span style="white-space:pre"></span>让窗口打开时最大化

相互传值：

<span style="white-space:pre">        private void btnChoosePic_Click(object sender, RoutedEventArgs e)        {            OpenFileDialog ofd = new OpenFileDialog();            ofd.Filter = "JPEG图片|*.jpg|PNG图片|*.png|BMP图片|*.bmp";            if (ofd.ShowDialog() == true)            {                string picFileName = ofd.FileName;                image1.Source = new BitmapImage(new Uri(picFileName));            }        }</span>
