FastReport 是功能齐全的报表控件，可以帮助开发者可以快速并高效地为.NET，VCL，COM，ActiveX应用程序添加报表支持，由于其独特的编程原则，现在已经成为了Delphi平台最优秀的报表控件，支持将编程开发中的报表信息输出为TXT、PDF等多种文件格式，是编程开发人员必备的报表工具。

FastReport .Net是一款全功能的Windows Forms、ASP.NET和MVC报表分析解决方案，使用FastReport .Net可以创建独立于应用程序的.NET报表。

在上篇文章中，我们学习了如何使用FastReport .NET在Ubuntu 22.04.1 LTS系统中的.JetBrains Rider上创建PDF文档。本次将分享FastReport .NET 在 JetBrains Rider 中工作的最简单方法——使用 Fast Reports 中的私有 NuGet 服务器。

因此，本文主要描述在购买FastReport .NET后如何添加NuGet包，从而在Ubuntu 22.04.1 LTS系统中的.NET IDE上创建、构建和导出PDF报告/文档的过程。

单击IDE底部的NuGet选项卡，然后单击Sources选项卡。

现在通过点击“+”来添加一个新的存储库，并输入必要的数据:

- Name—不带空格的源名称(例如FastReport);
- URL—https://nuget.fast-report.com/api/v3/index.json;
- User—来自Fast Reports帐户的电子邮箱;
- Password—来自Fast Reports帐户的密码。

您将看到存储库:

现在我们将安装FastReport Core 包。为此，请转到“Packages”选项卡并通过FastReport存储库过滤包。然后，安装找到的包。

安装成功，您将收到通知。

接下来，从代码中创建一个模板，为此我们将执行以下操作：添加到Program.cs:

using System.Drawing;
using FastReport;
using FastReport.Export.Pdf;
using FastReport.Utils;

接下来，将 CreateDataSet 添加到下面的 Program.cs 中：

Report report = new Report();
CreateReportTemplate();
ExportToPDF();

然后，添加创建报表模板函数CreateReportTemplate：

void CreateReportTemplate()
{
// adding a report page
ReportPage page = new ReportPage();// creating a date band
DataBand data = new DataBand();
PageHeaderBand dataText = new PageHeaderBand();//creating a header
ReportTitleBand titleBand = new ReportTitleBand();
TextObject employeeIdText = new TextObject();
TextObject employeeNameText = new TextObject();
TextObject idText = new TextObject();
TextObject nameText = new TextObject();
TextObject titleText = new TextObject();
//registering the data source
report.RegisterData(dataSet);
//enabling on the data table
report.GetDataSource("Employees").Enabled = true;
//adding a page to the template
report.Pages.Add(page);
// add to the page: data,data Text, titleBand
// and set the unique name of the page
page.AddChild(data);
page.AddChild(dataText);
page.AddChild(titleBand);
page.CreateUniqueName();
// set the unique name titleBand
// and set the band settings
titleBand.CreateUniqueName();
titleBand.Height = Units.Centimeters * 1.5f;
titleText.Bounds = new RectangleF(300, 0, Units.Centimeters * 10, Units.Centimeters * 0.5f);
titleText.Text = "Employees";
titleText.Font = new Font("Arial", 14, FontStyle.Bold);
titleText.VertAlign = VertAlign.Center;// set the unique name data
// and set the data settings
data.CreateUniqueName();
data.DataSource = report.GetDataSource("Employees");
data.Height = Units.Centimeters * 0.5f;// set a unique dataText name
// and set the dataText settings
dataText.CreateUniqueName();
dataText.Height = Units.Centimeters * 0.8f;// setting the unique name employeeIdText
// and set the employeeIdText, idText settings
employeeIdText.Parent = data;
employeeIdText.CreateUniqueName();
employeeIdText.Bounds = new RectangleF(0, 0, Units.Centimeters * 10, Units.Centimeters * 0.5f);
idText.Bounds = new RectangleF(0, 0, Units.Centimeters * 10, Units.Centimeters * 0.5f);
idText.Text = "ID";
employeeIdText.Text = "[Employees.ID]";// set the unique name employeeNameText
// and set the employeeNameText, nameText settings
employeeNameText.Parent = data;
employeeNameText.CreateUniqueName();
employeeNameText.Bounds = new RectangleF(50, 0, Units.Centimeters * 10, Units.Centimeters * 0.5f);
nameText.Bounds = new RectangleF(50, 0, Units.Centimeters * 10, Units.Centimeters * 0.5f);
nameText.Text = "Name";
employeeNameText.Text = "[Employees.Name]";// add on data band: employeeIdText, employeeNameText
data.AddChild(employeeIdText);
data.AddChild(employeeNameText);// add on dataText band: idText, nameText
dataText.AddChild(idText);
dataText.AddChild(nameText);// add on titleBand band: itleText
titleBand.AddChild(titleText);
}

接下来，添加创建ExportToPDF报表模板的功能，并将报表导出命名为“Report.pdf”:

void ExportToPDF()
{
// running the report
report.Prepare();
// creating an export instance
PDFExport export = new PDFExport();
report.Export(export, "test.pdf");
// disposing the resources used by the report
report.Dispose();
}

最后，启动控制台应用程序。如果您收到响应 Process finished with exit code 0，那么您之前做的每一步，打开报告，在我们的例子中，它是路径:

/home/alex/RiderProjects/ReportPDF_Core_ConsoleApp/ReportPDF_Core_ConsoleApp/bin/Debug/net6.0/test .pdf:

由此，我们得到了一个从数据集构建的简单报表/PDF文档。

在本文中，我们讨论了绑定JetBrains Rider (C#) + .NET Core + Console Application + FastReport .NET Core + Linux (Ubuntu 22.04.1 LTS) ，并从PDF数据集构建了一个报告。当然，我们确保.NET平台可以在没有Microsoft Visual Studio的情况下轻松使用，因为Linux根本没有它。
