 how to edit or update pdf file using c#

first we need to install plugin of nuget

"Spire.Pdf"

1).Create Model Classes

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

namespace EncriptionDecription.Models

{

    public class PDFModel

    {

        public HttpPostedFileBase ImageFile { set; get; }

        public int CompanyID { set; get; }

    }

    public class Company{

        public int ID { set; get; }

        public string Name { set; get; }

        public string Url { set; get; }

        public string Logo { set; get; }

    }

}

2).Create Controller 

using EncriptionDecription.Models;

using Spire.Pdf;

using Spire.Pdf.General.Find;

using Spire.Pdf.Graphics;

using System;

using System.Collections.Generic;

using System.Drawing;

using System.Web.Mvc;

namespace EncriptionDecription.Controllers

{

    public class PDFController : Controller

    {

        public List<Company> Companies = new List<Company>();

        public  PDFController()

        {

            Companies.Add(new Company

            {

                ID=1,Name="Tritex",Url="Tritexsolutions.com",Logo="LogoTritex"

            });

            Companies.Add(new Company

            {

                ID = 2,

                Name = "Nextgen",

                Url = "Nextgen.com",

                Logo = "LogoNextgen"

            });

        }

        public ActionResult Index()

        {

            ViewBag.myfile = "";

            TempData["Companies"] = this.Companies;

            return View();

        }

        [HttpPost]

        public ActionResult Index(PDFModel pdfmodel)

        {

            TempData["Companies"] = this.Companies;

            string rootpath= @"C:\Users\rituraj.vaishanav\source\repos\EncriptionDecription\EncriptionDecription\Files\";

            Spire.Pdf.PdfDocument pdfDoc = new Spire.Pdf.PdfDocument();

            pdfDoc.LoadFromFile(rootpath + pdfmodel.ImageFile.FileName);

            var pages = pdfDoc.Pages;

            foreach (PdfPageBase page in pages)

            {

                PdfTextFindCollection CompanyLogo = page.FindText("<CompanyLogo></CompanyLogo>", TextFindParameter.IgnoreCase);

                PdfTextFindCollection CompanyName = page.FindText("<CompanyName></CompanyName>", TextFindParameter.IgnoreCase);

                PdfTextFindCollection pdfsharptext = page.FindText("Evaluation Warning : The document was created with Spire.PDF for .NET.", TextFindParameter.IgnoreCase);

                var company = this.Companies.Find(x => x.ID == pdfmodel.CompanyID);

                String logoText = company.Logo;

                String nameText = company.Url;

                //Creates a brush

                PdfBrush brush = new PdfSolidBrush(Color.DarkBlue);

                //Defines a font

                PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", 12f, FontStyle.Regular));

                RectangleF rec;

                foreach (PdfTextFind find in CompanyLogo.Finds)

                {

                    rec = find.Bounds;

                    page.Canvas.DrawRectangle(PdfBrushes.White, rec);

                    page.Canvas.DrawString(logoText, font, brush, rec);

                }

                foreach (PdfTextFind find in CompanyName.Finds)

                {

                    rec = find.Bounds;

                    page.Canvas.DrawRectangle(PdfBrushes.White, rec);

                    page.Canvas.DrawString(nameText, font, brush, rec);

                }

                foreach (PdfTextFind find in pdfsharptext.Finds)

                {

                    rec = find.Bounds;

                    page.Canvas.DrawRectangle(PdfBrushes.White, rec);

                    page.Canvas.DrawString("", font, brush, rec);

                }

                //

            }

            var filename = rootpath + "new" + Guid.NewGuid() + ".pdf";

            pdfDoc.SaveToFile(filename);

            ViewBag.myfile = filename;

            return View();

        }

}

3).Create HTML

@using EncriptionDecription.Models;

@{

    ViewBag.Title = "Index";

}

<div class="row">

    <div class="col-md-8 col-md-offset-2">

        @using (Html.BeginForm("Index", "PDF", FormMethod.Post, new { enctype = "multipart/form-data" }))

        {

            <div class="row">

                <div class="col-md-6">

                    <input type="file" name="ImageFile" required />

                </div>

                <div class="col-md-6">

                    <select name="CompanyID">

                        @foreach (var company in (List<Company>)TempData["Companies"])

                        {

                        <option value="@company.ID">@company.Name</option>

                        }

                    </select>

                    <input type="submit" value="Create" class="btn btn-default" />

                </div>

            </div>

            if (ViewBag.myfile != "")

            {

                <a href="@ViewBag.myfile">download file</a>;

            }

        }

    </div>

</div>
