In Any Web API project and  Web Application, the most common requirement is to generate a report in PDF format. In this article, we will learn, How to Export Data from a Database to PDF Document using Asp.net Core MVC C#.

We are going to use the DinkToPDF library.  In this library, we can easily generate PDF documents while working on the .Net Core Web API and Web Application.

Prerequisites

  • Download and install .Net Core 6.0 SDK from here
  • Download and Install Microsoft Visual Studio 2022 from here
  • Sql-Server

Generate PDF From Database

Create an Asp.Net Core Web App

  • Open Visual Studio and click the Create New Project Option
  • Select the Template
Export Data into PDF Document using Asp.net Core MVC C#
  • Enter the name of the Application
Export Data into PDF Document using Asp.net Core MVC C#

Install NuGet Packages

  • Microsoft Entity Framework Core Sql Server.
  • Microsoft Entity Framework Core Tools
  • DinkToPdf Library

After Installation, we need to import the native library file to the project root Path.

Configure appsettings.json

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "ConnectionStrings": {
    "sqlconnection": "Server=(local)\\MSSQL;Database=Inventory;Trusted_Connection=True;MultipleActiveResultSets=true",
    

  },
  "AllowedHosts": "*"
}

Create Model

Create Model class and DbContext Class

Customer.cs

using System.ComponentModel.DataAnnotations;
namespace Asp.netcore_Tutorials.Models
{
    public class Customer
    {
        [Key]
        public int id { get; set; }
        public string firstName { get; set; }
        public string lastName { get; set; }
        public string job { get; set; }
        public float amount { get; set; }
        public DateTime tdate { get; set; }
    }
}

CustDbcontext.cs

using Microsoft.EntityFrameworkCore;

namespace Asp.netcore_Tutorials.Models
{
    public class CustDbcontext :DbContext 
    {

        public CustDbcontext(DbContextOptions<CustDbcontext> options):base(options)
        {
        }
        public virtual DbSet<Customer> Customers { get; set; } 
    }
}

Create Interface and Concrete Class

ICustomer.cs

using Asp.netcore_Tutorials.Models;
using Microsoft.AspNetCore.Mvc.Rendering;
using System.Collections;
using System.Data;

namespace Asp.netcore_Tutorials.Repository
{
    public interface ICustomer
    { 
        Task<IEnumerable<Customer>> GetCustomer(); 
    } 
}

Concrete Class CustomerDetail.cs

using Microsoft.AspNetCore.Http;
using System.Data;
using System.Data.OleDb;
using System.Data.SqlClient;
using System.IO;
using ClosedXML.Excel;
using Microsoft.AspNetCore.Mvc;
using System.Collections;
using Asp.netcore_Tutorials.Models;
using Microsoft.EntityFrameworkCore;
using DocumentFormat.OpenXml.Wordprocessing;
using Microsoft.AspNetCore.Mvc.Rendering;

namespace Asp.netcore_Tutorials.Repository
{
    public class CustomerDetail : ICustomer
    {       
        private readonly CustDbcontext _custDbcontext;
        public CustomerDetail(CustDbcontext custDbcontext)
        {   
            _custDbcontext = custDbcontext;
        }      

        public async Task<IEnumerable<Customer>> GetCustomer()
        {
            return  await _custDbcontext.Customers.ToListAsync();
        } 
    }
}

Configure Program.cs

using Asp.netcore_Tutorials.Models;
using Asp.netcore_Tutorials.Repository;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.DependencyInjection;
using System.Configuration;
using Microsoft.AspNetCore.Session;
using DinkToPdf;
using DinkToPdf.Contracts;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container. 
builder.Services.AddDbContext<CustDbcontext>(conn => conn.UseSqlServer(builder.Configuration.GetConnectionString("sqlconnection"))); 

builder.Services.AddSingleton(typeof(IConverter), new SynchronizedConverter(new PdfTools()));

builder.Services.AddControllersWithViews();

builder.Services.AddSession();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Home/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();

app.UseStaticFiles();

app.UseRouting();

app.UseAuthorization();

app.UseSession();

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");

app.Run();

Migration

Add-Migration 'Initial-Create'
Update-Database

Create View Model

using Asp.netcore_Tutorials.Models;

namespace Asp.netcore_Tutorials.ViewModel
{
    public class menuViewModel
    { 
        public IEnumerable<Customer> CustomerList { get; set; }
    }
}

Create Controller

ExportToPDFController.cs

using Asp.netcore_Tutorials.Repository;
using Asp.netcore_Tutorials.ViewModel;
using DinkToPdf;
using DinkToPdf.Contracts;
using DocumentFormat.OpenXml.ExtendedProperties;
using Microsoft.AspNetCore.Mvc;
using System.Text;

namespace Asp.netcore_Tutorials.Controllers
{
    public class ExportToPDFController : Controller
    {
        private readonly ICustomer _customer;
        private IWebHostEnvironment _environment;
        private readonly IConverter _converter;
        public ExportToPDFController(ICustomer customer, IWebHostEnvironment environment,IConverter converter)
        {
            _customer = customer;
            _environment = environment;
            _converter = converter;
        }

        public IActionResult Index()
        {
            menuViewModel menuViewModel = new menuViewModel();

            menuViewModel.CustomerList = _customer.GetCustomer().Result;

            return View(menuViewModel);
        }

        [HttpPost]
        [AutoValidateAntiforgeryToken]
        public IActionResult ExporttoPDF()
        {
            string uploadpath = _environment.WebRootPath;
            string dest_path = Path.Combine(uploadpath, "PDF");

            if (!Directory.Exists(dest_path))
            {

                Directory.CreateDirectory(dest_path);
            }           

            var globalSettings = new GlobalSettings
            {
                Orientation = Orientation.Portrait,
                PaperSize = PaperKind.A4,
                ColorMode = ColorMode.Color,
                Margins = new MarginSettings { Top = 20, Bottom = 10 },
                DocumentTitle = "Export to PDF",
                Out  = dest_path + @"\Document.pdf"
            };            
            var objects = new ObjectSettings()
            {
                HtmlContent = GetTablecontextHtml()
            };

            var PdfDoc = new HtmlToPdfDocument
            {
                GlobalSettings= globalSettings,
                Objects = { objects }

            };

            _converter.Convert(PdfDoc);

            return View();
        }

        public  string GetTablecontextHtml()
        {
            var customer = _customer.GetCustomer().Result;

            var customerdata = new StringBuilder();

            customerdata.Append(@"<html>
                                  <head>

Customize View

 
@model  Asp.netcore_Tutorials.ViewModel.menuViewModel

    <div class="row">   
    <form method="post" enctype="multipart/form-data" asp-controller="ExportToPDF" asp-action="ExportToPDF">

            <td>Salary</td>
            </tr>
        </thead>
        <tbody

        @foreach (var item in Model.CustomerList)
        {
            <tr>
