wpf应用程序打印标签

新建一个wpf应用程序，Xaml如下：

<Window x:Class="CreateBarCodeDemo.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>

        <StackPanel>

            <Button Height="40" Width="80" Margin="20" Content="打印" Click="btnPrint_Click"/>

        </StackPanel>

    </Grid>

</Window>

项目引用BarcodeLib.dll(用来生成条码)。

两个窗体界面效果如下：

主窗体：

打印窗体：

主窗体的后置代码如下：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

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.Navigation;

using System.Windows.Shapes;

namespace CreateBarCodeDemo

{

    /// <summary>

    /// MainWindow.xaml 的交互逻辑

    /// </summary>

    public partial class MainWindow : Window

    {

        public MainWindow()

        {

            InitializeComponent();

        }

        private void btnPrint_Click(object sender, RoutedEventArgs e)

        {

            PrintWindow pw = new PrintWindow("路飞", "男", , "海贼", "橡胶果实", "船长", "500000000$");

            pw.ShowDialog();

        }

    }

}

点击打印时，ShoW出打印窗体；

通过打印窗体的构造函数，传入要打印的信息；

打印窗体呈现完后，执行了Window_ContentRendered事件，进行打印标签；

打印方法里通过调用BarcodeLib.Barcode生成一个条码；

最后将整个打印窗体的布局打印出来。
