1.如何在WPF应用程序中使用FastReport.Net控件？

您应该为此使用WindowsFormsHost控件：

0）在FastReport.dll上添加引用；

1）如果要使用PreviewControl，则将属性添加到Window（Page）标记中：xmlns：fr =“ clr-namespace：FastReport.Preview; assembly = FastReport”，xmlns：fr1 =“ clr-namespace：FastReport.Design; assembly = FastReport”-if DesignerControl;

2）将WindowsFormsHost标记添加到您的XAML标记中：

<WindowsFormsHost HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Grid.Column="0" Grid.ColumnSpan="3"> </WindowsFormsHost> 3）将子级添加到WindowsFormsHost中：<fr：PreviewControl> </ fr：PreviewControl>或<fr1：Designer> </ fr1：Designer>。完整的标记应如下所示：

<Window 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" x:Class="WpfApplication1.MainWindow" Title="MainWindow" Height="375.977" Width="939.258" xmlns:fr="clr-namespace:FastReport.Preview;assembly=FastReport"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width=""/> <ColumnDefinition Width=""/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <WindowsFormsHost HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Grid.Column="0" Grid.ColumnSpan="3"> fr:PreviewControl</fr:PreviewControl> </WindowsFormsHost> </Grid> </Window> 2.如何以编程方式设置Format的值？

您可以使用以下代码在脚本或项目中执行此操作：

FastReport.Format.NumberFormat format = new FastReport.Format.NumberFormat(); format.UseLocale = false; format.DecimalDigits = 2; format.DecimalSeparator = "."; format.GroupSeparator = ","; 然后：

textObject.Formats.Clear(); textObject.Formats.Add(format); 3.如何在MSChartObject中创建带有间隙的行？

您应该创建基本的System.Windows.Forms.DataVisualization.Charting.Series对象，并在此处创建行。之后，应为MSChartObject基本图表分配创建的系列（MSChart1.Chart.Series.Add（series）;）不要忘记在“报表”->“脚本”菜单和命名空间System.Windows.Forms中添加 System.Windows.Forms.DataVisualization.dll。 .DataVisualization.Charting。

带有间隙的线的示例：

. . using System.Windows.Forms.DataVisualization.Charting;

namespace FastReport { public class ReportScript { private void MSChart1_BeforePrint(object sender, EventArgs e) { Series series = new Series("sample"); series.ChartType = SeriesChartType.Line; series.BorderWidth = 2; series.MarkerSize = 5;

series.Points.Add(new DataPoint(0, 1)); series.Points.Add(new DataPoint(1, 2)); DataPoint dp = new DataPoint(2, double.NaN); dp.IsEmpty = true; series.Points.Add(dp); series.Points.Add(new DataPoint(3, 5)); series.Points.Add(new DataPoint(4, 8));

MSChart1.Chart.Series.Add(series);

} } } 结果：

4.如何从代码创建MSChartObject？

1.创建新的MSChart对象，设置宽度，高度和图例：

MSChartObject MSChart1 = new MSChartObject(); MSChart1.Width = 300; MSChart1.Height = 300; MSChart1.Chart.Legends.Add(new Legend() { Name = "Legend1", Title="Legend title"}); 2.创建ChartArea对象，设置名称，轴标题，并将创建的ChartArea分配给MSChart： ChartArea chartArea1 = new ChartArea(); chartArea1.Name = "ChartArea1"; chartArea1.Axes[0].Title = "X name"; chartArea1.Axes[1].Title = "Y name"; MSChart1.Chart.ChartAreas.Add(chartArea1); 3.创建系列对象，设置图表类型，边框宽度，添加点并将系列分配给图表： Series series = new Series("sample"); series.ChartType = SeriesChartType.Line; series.BorderWidth = 2; series.Points.Add(new DataPoint(0, 1)); series.Points.Add(new DataPoint(1, 2)); series.Points.Add(new DataPoint(3, 5)); series.Points.Add(new DataPoint(4, 8));

MSChart1.Chart.Series.Add(series); 4.将创建的MSChart分配给DataBand： Report report = new Report(); report.Load("ok.frx"); DataBand db = report.FindObject("Data1") as DataBand;

MSChart1.Parent = db; 完整的代码段： MSChartObject MSChart1 = new MSChartObject(); MSChart1.Width = 300; MSChart1.Height = 300; MSChart1.Chart.Legends.Add(new Legend() { Name = "Legend1", Title="Legend title"});

ChartArea chartArea1 = new ChartArea(); chartArea1.Name = "ChartArea1"; chartArea1.Axes[0].Title = "X name"; chartArea1.Axes[1].Title = "Y name"; MSChart1.Chart.ChartAreas.Add(chartArea1);

Series series = new Series("sample"); series.ChartType = SeriesChartType.Line; series.BorderWidth = 2; series.Points.Add(new DataPoint(0, 1)); series.Points.Add(new DataPoint(1, 2)); series.Points.Add(new DataPoint(3, 5)); series.Points.Add(new DataPoint(4, 8));

MSChart1.Chart.Series.Add(series);

Report report = new Report(); report.Load("ok.frx"); DataBand db = report.FindObject("Data1") as DataBand; MSChart1.Parent = db; 结果：
