FastReport 是功能齊全的報表控件，可以幫助開發(fā)者可以快速并高效地為.NET，VCL，COM，ActiveX應(yīng)用程序添加報表支持，由于其獨特的編程原則，現(xiàn)在已經(jīng)成為了Delphi平臺最優(yōu)秀的報表控件，支持將編程開發(fā)中的報表信息輸出為TXT、PDF等多種文件格式，是編程開發(fā)人員必備的報表工具。

FastReport .Net是一款全功能的Windows Forms、ASP.NET和MVC報表分析解決方案，使用FastReport .Net可以創(chuàng)建獨立于應(yīng)用程序的.NET報表。

FastReport.NET官方版下載

在上篇文章中，我們學(xué)習(xí)了如何使用FastReport .NET在Ubuntu 22.04.1 LTS系統(tǒng)中的.JetBrains Rider上創(chuàng)建PDF文檔。本次將分享FastReport .NET 在 JetBrains Rider 中工作的最簡單方法——使用 Fast Reports 中的私有 NuGet 服務(wù)器。

因此，本文主要描述在購買FastReport .NET后如何添加NuGet包，從而在Ubuntu 22.04.1 LTS系統(tǒng)中的.NET IDE上創(chuàng)建、構(gòu)建和導(dǎo)出PDF報告/文檔的過程。

單擊IDE底部的NuGet選項卡，然后單擊Sources選項卡。

現(xiàn)在通過點擊“+”來添加一個新的存儲庫，并輸入必要的數(shù)據(jù):

- Name—不帶空格的源名稱(例如FastReport);
- URL—//nuget.fast-report.com/api/v3/index.json;
- User—來自Fast Reports帳戶的電子郵箱;
- Password—來自Fast Reports帳戶的密碼。

您將看到存儲庫:

現(xiàn)在我們將安裝FastReport Core 包。為此，請轉(zhuǎn)到“Packages”選項卡并通過FastReport存儲庫過濾包。然后，安裝找到的包。

安裝成功，您將收到通知。

接下來，從代碼中創(chuàng)建一個模板，為此我們將執(zhí)行以下操作：添加到Program.cs:

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

接下來，將 CreateDataSet 添加到下面的 Program.cs 中：

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

然后，添加創(chuàng)建報表模板函數(shù)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);
}

接下來，添加創(chuàng)建ExportToPDF報表模板的功能，并將報表導(dǎo)出命名為“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，啟動控制臺應(yīng)用程序。如果您收到響應(yīng) Process finished with exit code 0，那么您之前做的每一步，打開報告，在我們的例子中，它是路徑:

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

由此，我們得到了一個從數(shù)據(jù)集構(gòu)建的簡單報表/PDF文檔。

在本文中，我們討論了綁定JetBrains Rider (C#) + .NET Core + Console Application + FastReport .NET Core + Linux (Ubuntu 22.04.1 LTS) ，并從PDF數(shù)據(jù)集構(gòu)建了一個報告。當(dāng)然，我們確保 .NET 平臺可以在沒有Microsoft Visual Studio的情況下輕松使用，因為Linux根本沒有它。
