搭建Wpf框架(3) —— Wpf实现打印报表
Wpf流文档自带打印功能，那么使用MVVM轻松可以实现打印功能。
1.新建一个窗体，放置流文档的父容器
<Window x:Class="AIStudio.Wpf.BasePage.Views.PrintPreviewWindow"
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:AIStudio.Wpf.BasePage.Views"
mc:Ignorable="d"
Title="打印预览窗口" Height="736" Width="882">
<Grid>
<DocumentViewer Name="docViewer"></DocumentViewer>
</Grid>
</Window>
2.DocumentViewer加载FlowDocument的方法
public static void LoadXps(FlowDocument m_doc, DocumentViewer docViewer)
{
//构造一个基于内存的xps document
MemoryStream ms = new MemoryStream();
Package package = Package.Open(ms, FileMode.Create, FileAccess.ReadWrite);
Uri DocumentUri = new Uri("pack://InMemoryDocument.xps");
PackageStore.RemovePackage(DocumentUri);
PackageStore.AddPackage(DocumentUri, package);
XpsDocument xpsDocument = new XpsDocument(package, CompressionOption.Fast, DocumentUri.AbsoluteUri);
//将flow document写入基于内存的xps document中去
XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter(xpsDocument);
writer.Write(((IDocumentPaginatorSource)m_doc).DocumentPaginator);
//获取这个基于内存的xps document的fixed document
docViewer.Document = xpsDocument.GetFixedDocumentSequence();
//关闭基于内存的xps document
xpsDocument.Close();
}
3.绘制自己要打印的页面MVVM模式。
<FlowDocument xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
ColumnWidth="400" FontSize="14" FontFamily="宋体"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
TextOptions.TextFormattingMode="Display">
<Paragraph TextAlignment="Center" FontSize="16" FontWeight="Bold">
<Run Text="{Binding DefFormName}"></Run>
</Paragraph>
<Paragraph>
<Run Text="因"></Run>
<Run Text="{Binding Text}" TextDecorations="Underline"></Run>
<Run Text="，本人想"></Run>
<Run Text="{Binding SubType}"></Run>
<Run Text="{Binding Flag}" TextDecorations="Underline"></Run>
<Run Text="{Binding Unit}"></Run>
<Run Text="，望领导批准！"></Run>
</Paragraph>
<Paragraph TextAlignment="Right">
<Run Text="谢谢!"></Run>
</Paragraph>
<Paragraph TextAlignment="Right">
<Run Text="申请人:"></Run>
<Run Text="{Binding ApplicantUserId}" TextDecorations="Underline"></Run>
</Paragraph>
</FlowDocument>
4.如果需要打印表格，那么xaml如下：
<FlowDocument xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:local="clr-namespace:AIStudio.Wpf.Base_Manage.Views"
ColumnWidth="400" FontSize="14" FontFamily="宋体"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
TextOptions.TextFormattingMode="Display">
<FlowDocument.Resources>
<Style TargetType="Table" x:Key="BorderedTable">
<Setter Property="CellSpacing" Value="0"></Setter>
<Setter Property="BorderThickness" Value="1"></Setter>
<Setter Property="BorderBrush" Value="#000"></Setter>
</Style>
<Style TargetType="TableCell" x:Key="BorderedCell">
<Setter Property="BorderThickness" Value="0.5"></Setter>
<Setter Property="BorderBrush" Value="#000"></Setter>
<Setter Property="Padding" Value="3"></Setter>
</Style>
</FlowDocument.Resources>
<Table Style="{StaticResource BorderedTable}">
<Table.Columns>
<TableColumn Width="*"></TableColumn>
<TableColumn Width="*"></TableColumn>
<TableColumn Width="*"></TableColumn>
<TableColumn Width="*"></TableColumn>
<TableColumn Width="*"></TableColumn>
<TableColumn Width="*"></TableColumn>
</Table.Columns>
<TableRowGroup Name="rowsDetails">
<TableRow FontWeight="Bold" >
<TableCell Style="{StaticResource BorderedCell}">
<Paragraph>用户名</Paragraph>
</TableCell>
<TableCell Style="{StaticResource BorderedCell}">
<Paragraph>姓名</Paragraph>
</TableCell>
<TableCell Style="{StaticResource BorderedCell}">
<Paragraph>性别</Paragraph>
</TableCell>
<TableCell Style="{StaticResource BorderedCell}">
<Paragraph>出生日期</Paragraph>
</TableCell>
<TableCell Style="{StaticResource BorderedCell}">
<Paragraph>所属部门</Paragraph>
</TableCell>
<TableCell Style="{StaticResource BorderedCell}">
<Paragraph>所属角色</Paragraph>
</TableCell>
</TableRow>
</TableRowGroup>
</Table>
</FlowDocument>
这个时候还需要在cs代码中添加数据行
class Base_UserDocumentRenderer : IDocumentRenderer
{
public void Render(FlowDocument doc, object data)
{
if (data is ObservableCollection<Base_UserDTO> items)
{
TableRowGroup groupDetails = doc.FindName("rowsDetails") as TableRowGroup;
Style styleCell = doc.Resources["BorderedCell"] as Style;
foreach (var item in items)
{
TableRow row = new TableRow();
TableCell cell = new TableCell(new Paragraph(new Run(item.UserName)));
cell.Style = styleCell;
row.Cells.Add(cell);
cell = new TableCell(new Paragraph(new Run(item.RealName)));
cell.Style = styleCell;
row.Cells.Add(cell);
cell = new TableCell(new Paragraph(new Run(item.SexText)));
cell.Style = styleCell;
row.Cells.Add(cell);
cell = new TableCell(new Paragraph(new Run(item.Birthday?.ToString("yyyy-MM-dd"))));
cell.Style = styleCell;
row.Cells.Add(cell);
cell = new TableCell(new Paragraph(new Run(item.DepartmentName)));
cell.Style = styleCell;
row.Cells.Add(cell);
cell = new TableCell(new Paragraph(new Run(item.RoleNames)));
cell.Style = styleCell;
row.Cells.Add(cell);
groupDetails.Rows.Add(row);
}
}
}
}
最后整理一下：

6.使用的地方
PrintPreviewWindow previewWnd = new PrintPreviewWindow("/AIStudio.Wpf.Base_Manage;component/Views/Base_UserFlowDocument.xaml", Data, new Base_UserDocumentRenderer()); previewWnd.ShowDialog();
最后打印以更新到源码中，欢迎大家下载。
