打印功能

- PrintDocument对象

- 调用PrintDocument.Print()方法

xaml:

<UserControl x:Class="PrintDemo.MainPage"    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"    mc:Ignorable="d"    d:DesignHeight="300" d:DesignWidth="400">    <Grid x:Name="LayoutRoot" Background="White">        <Canvas x:Name="cnvContainer">            <Border Height="120" Width="380" HorizontalAlignment="Left" Name="border1" VerticalAlignment="Top"                    Background="AliceBlue"/>            <TextBlock Text="Silverlight打印Demo"                       FontWeight="Bold" FontSize="20"/>            <ProgressBar Height="18" HorizontalAlignment="Right" Margin="0,50" x:Name="progressBar1"                         Value="75" VerticalAlignment="Top" Width="350"/>        </Canvas>        <Button Content="Print" Height="23"                HorizontalAlignment="Left" Margin="200"                x:Name="btnPrint" VerticalAlignment="Top"                Width="75" Click="btnPrint_Click"/>    </Grid></UserControl>

xaml.cs:

using System;using System.Collections.Generic;using System.Linq;using System.Net;using System.Windows;using System.Windows.Controls;using System.Windows.Documents;using System.Windows.Input;using System.Windows.Media;using System.Windows.Media.Animation;using System.Windows.Shapes;using System.Windows.Printing;namespace PrintDemo{    public partial class MainPage : UserControl    {        public MainPage()        {            InitializeComponent();        }        private void btnPrint_Click(object sender, RoutedEventArgs e)        {            PrintDocument document = new PrintDocument();            document.PrintPage += new EventHandler<PrintPageEventArgs>(document_PrintPage);            //上面那行代码及事件触发方法可以写成,这事一个匿名函数的写法            //document.PrintPage += (s, args) => { args.PageVisual = this.cnvContainer; };            //开始打印，并且显示打印机状态挂起打印时候显示的字符串            document.Print("开始打印。。。");                    }        void document_PrintPage(object sender, PrintPageEventArgs e)        {            e.PageVisual = this.cnvContainer;                    }    }}
