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>

新建打印窗体(wpf)，Xaml如下：

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", 19, "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。
