All C# Crystal Reports Tutorial in this website is based on the following database - crystaldb. So before you begin this section , please take a look at the database structure of crystaldb - Click Here C# crystaldb
If you are new to Crystal Reports and do not know how to create Crystal Reports from C# , please take a look at the section step by step tutorial for creating a Crystal Reports from C#.
In this section we are using our earlier program step by step tutorial for creating a Crystal Reports from C# for pull data from database to Crystal Reports . Before we start this section take a look at the step by step tutorial for creating a Crystal Reports from C# .
Here we are generating a Crystal Report from Product table and export the report content to an Excel format file.
Select the default form (Form1.cs) you created in C# and drag two buttons (Button1, Button2 ) and a CrystalReportViewer control to your form.
You have to include CrystalDecisions.CrystalReports.Engine in your C# Source Code.
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;



using System;
using System.Windows.Forms;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;

namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        ReportDocument cryRpt;

        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            cryRpt = new ReportDocument();
            cryRpt.Load(PUT CRYSTAL REPORT PATH HERE\\CrystalReport1.rpt");
            crystalReportViewer1.ReportSource = cryRpt;
            crystalReportViewer1.Refresh(); 
        }

        private void button2_Click(object sender, EventArgs e)
        {
            try
            {
                ExportOptions CrExportOptions ;
                  
                DiskFileDestinationOptions CrDiskFileDestinationOptions = new DiskFileDestinationOptions();
                ExcelFormatOptions CrFormatTypeOptions = new ExcelFormatOptions();
                CrDiskFileDestinationOptions.DiskFileName = "c:\\csharp.net-informations.xls";
                CrExportOptions = cryRpt.ExportOptions;
                CrExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;
                CrExportOptions.ExportFormatType = ExportFormatType.Excel;
                CrExportOptions.DestinationOptions = CrDiskFileDestinationOptions;
                CrExportOptions.FormatOptions = CrFormatTypeOptions;
                cryRpt.Export();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }
        }
    }
}

cryRpt.Load(PUT CRYSTAL REPORT PATH HERE\\CrystalReport1.rpt");
The Crystal Reports file path in your project files location, there you can see CrystalReport1.rpt . So give the full path name of Crystal Reports file like c:\projects\crystalreports\CrystalReport1.rpt

When you run this program you will get the Excel file (csharp.net-informations.xls) in your computer's C:
