本文小编为大家详细介绍".NET中如何使用FastReport实现打印功能"，内容详细，步骤清晰，细节处理妥当，希望这篇".NET中如何使用FastReport实现打印功能"文章能帮助大家解决疑惑，下面跟着小编的思路慢慢深入，一起来学习新知识吧。

一、新建一个窗体程序，窗体上面有设计界面和预览界面两个按钮，分别对应FastReport的设计和预览功能，其实现代码如下：using FastReport;using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Data.SqlClient;using System.Drawing;using System.IO;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;using Dapper;namespace FastReportDemo{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void btn_Design_Click(object sender, EventArgs e) { // 显示设计界面 CreateReport(true); } private void CreateReport(bool tfDesigin) { // 获得当前程序的运行路径 string path = Application.StartupPath; // 定义报表 Report report = new Report(); string strDirectory = path + "\\ReportFiles"; // 判断文件路径是否存在，不存在则创建文件夹 if (!Directory.Exists(strDirectory)) { // 不存在就创建目录 Directory.CreateDirectory(strDirectory); } // 判断文件是否存在 if (!File.Exists(strDirectory + "\\产品明细.frx")) { report.FileName = strDirectory + "\\产品明细.frx"; } else { report.Load(strDirectory + "\\产品明细.frx"); } // 创建报表文件的数据源 DataSet ds = new DataSet(); DataTable dt = GetDataSource(); DataTable dtSource = dt.Copy(); dtSource.TableName = "ProductDetail"; ds.Tables.Add(dtSource); report.RegisterData(ds); if (tfDesigin) { // 打开设计界面 report.Design(); } else { // 打开预览界面 report.Show(); } } private DataTable GetDataSource() { DataTable dt = new DataTable(); // 数据库连接 string strCon = @"Initial Catalog=StudentSystem; Integrated Security=False;User Id=sa;Password=1qaz@WSX;Data Source=127.0.0.1;Failover Partner=127.0.0.1;Application Name=TransForCCT"; SqlConnection conn = new SqlConnection(strCon); string strSql = @"SELECT p.ProductId,p.ProductName,p.Price,c.CategoryName FROM ProductDetail p INNER JOIN Category c ON p.CategoryId=c.CategoryId"; // 使用Dapper获取数据 IDataReader reader = conn.ExecuteReader(strSql); dt.Load(reader); return dt; } private void btn_Show_Click(object sender, EventArgs e) { // 显示预览界面 CreateReport(false); } }}二、运行程序，点击设计界面，打开FastReport的设计界面：

三、选择数据源

在设计之前要先选择数据源，只有选择了数据源，报表文件才会有数据。

1、在Data文件夹下面选择"Choose Report Data"选项：

2. Select the data source to be used in the Choose Report Data interface:

3. After clicking the "OK" button, the selected data source will be displayed on the right side of the design interface:

IV. Overall structure of the report:

V. Design report title 1. Design report title to use "A" control:

2. Drag the "A" control on the left to the report title area:

3. Set the title:

Double-click the A control in the report title area to open the interface for inputting titles:

4. Enter the report title and click the "OK" button:

The report title area displays the designed title and allows you to set the alignment of the title.

VI: Design report data area 1. Design report data, to use table controls, table controls are shown in the following figure:

2. Drag the table to the data area and design the number of rows and columns to be displayed in the table:

3. Contents displayed in the table:

4. Form interface:

VII. Setting Table Events

Add data binding events to tables:

After setting the event, double-click the event to enter the code editing interface. The code for binding the event is as follows:

using System;using System.Collections;using System.Collections.Generic;using System.ComponentModel;using System.Windows.Forms;using System.Drawing;using System.Data;using FastReport;using FastReport.Data;using FastReport.Dialog;using FastReport.Barcode;using FastReport.Table;using FastReport.Utils;namespace FastReport{ public class ReportScript { private void Table1_ManualBuild(object sender, EventArgs e) { //Set data source DataSourceBase rowData = Report.GetDataSource("ProductDetail"); rowData.Init(); Table1.PrintRow(0); Table1.PrintColumns(); bool tfvar = false; while (rowData.HasMoreRows) { tfvar = true; Table1.PrintRow(1); Table1.PrintColumns(); rowData.Next(); } if (! tfvar) { Table1.PrintRow(2); Table1.PrintColumns(); } {}} VIII. Print time displayed in footer:

IX. Save Report Format

After designing the report format, remember to save:

X. Effect

Because the interface is too large, it is divided into two screenshots:
