2.
Button Control (btnSelect, btnCreatePDF)
Here I implemented the Code for converting
Text Document into PDF Document using iTextSharp Tool.
The Code:
1. Select the Text File (code for “Select File” Button).
using (OpenFileDialog file = new OpenFileDialog()){ //Show the Dialog Box & Select the File file.ShowDialog(); //Assign Input FileName to TextBox txtInput.Text = file.FileName;}
//Assign Output FileName to TextBox
txtOutput.Text = (txtInput.Text).Replace(".txt", ".pdf");
Listing 1
2.
Convert
Text File into a PDF File (code for “Create
PDF” Button).
//Read the Data from Input File
StreamReader rdr = new StreamReader(txtInput.Text);
//Create a New instance on Document Class
Document doc = new Document();
//Create a New instance of PDFWriter Class for Output File
PdfWriter.GetInstance(doc, new FileStream(txtOutput.Text,FileMode.Create));
//Open the Document
doc.Open();
//Add the content of Text File to PDF File
doc.Add(new Paragraph(rdr.ReadToEnd()));
//Close the Document
doc.Close();
MessageBox.Show("Conversion
Successful....");
//Open the Converted PDF File
System.Diagnostics.Process.Start(txtOutput.Text);
