2.  using iTextSharp.text.pdf;

3.  using System;

5.  using System.Threading;

6.   using System.Windows.Forms;

About controls used:-

1.       TextBox Control (txtInput, txtOutput)

2.       Button Control (btnSelect, btnCreatePDF)  

Here I’m implementing to convert text document into pdf file use iTextSharp dll.

Button1:

  privatevoid button1_Click(object sender, EventArgs e)
        {
            var t = newThread((ThreadStart)(() =>
            {
                OpenFileDialog op = newOpenFileDialog();
                if (op.ShowDialog() == System.Windows.Forms.DialogResult.OK)
                {
                    txtInput.Text = op.FileName;
                    txtOutput.Text = (txtInput.Text).Replace(".txt", ".pdf");
                }
            }));
            t.SetApartmentState(ApartmentState.STA);
            t.Start();
        }

Button2:

  privatevoid button2_Click(object sender, EventArgs e)
        {
            StreamReader rdr = newStreamReader(txtInput.Text);
            Document doc = newDocument();
           
            PdfWriter.GetInstance(doc, newFileStream(txtOutput.Text, FileMode.Create));
            doc.Open();
            doc.Add(newParagraph(rdr.ReadToEnd()));
            doc.Close();
            MessageBox.Show("Conversion Successful....");
            System.Diagnostics.Process.Start(txtOutput.Text);
        }

Form_Load:

  privatevoid Form1_Load(object sender, EventArgs e)
        {
            Form1.CheckForIllegalCrossThreadCalls = false;
        }

Output:

in my next post i'll explain about Substring methods in C#
