Creation of PDF Document in 5 easy steps

Step 1: First create an instance of document object

Document myDocument= new Document(PageSize.A4.Rotate());


Step 2: Now create a writer that listens to this doucment and writes the document to desired Stream.

PdfWriter.GetInstance(myDocument, new FileStream("Salman.pdf", FileMode.Create));


Step 3: Open the document now using

myDocument.Open();

Step 4: Now add some contents to the document

myDocument.add( new Paragraph ( "First Pdf File made by Salman using iText"));

Step 5: Remember to close the documnet

myDocument.close();



// Code

using System;
using System.IO;
using System.Diagnostics;

using iTextSharp.text;
using iTextSharp.text.pdf;

public class iTextDemo
{
public static void Main()
{
Console.WriteLine("iText Demo");

// step 1: creation of a document-object
Document myDocument = new Document(PageSize.A4.Rotate());

try
{

// step 2:
// Now create a writer that listens to this doucment and writes the document to desired Stream.

PdfWriter.GetInstance(myDocument, new FileStream("Salman.pdf", FileMode.Create));

// step 3: Open the document now using
myDocument.Open();

// step 4: Now add some contents to the document
myDocument.Add(new Paragraph("First Pdf File made by Salman using iText"));

}
catch(DocumentException de)
{
Console.Error.WriteLine(de.Message);
}
catch(IOException ioe)
{
Console.Error.WriteLine(ioe.Message);
}

// step 5: Remember to close the documnet

myDocument.Close();
}
}

tag:- Create PDF Files on fly in C#

If you've got a Stream in .NET - whether its fetched from a HttpWebRequest or read from another file - you can easily save this stream to another file using the following code.

// readStream is the stream you need to read
// writeStream is the stream you want to write to
private void ReadWriteStream(Stream readStream, Stream writeStream)
{
int Length = 256;
Byte [] buffer = new Byte[Length];
int bytesRead = readStream.Read(buffer,0,Length);
// write the required bytes
while( bytesRead > 0 )
{
writeStream.Write(buffer,0,bytesRead);
bytesRead = readStream.Read(buffer,0,Length);
}
readStream.Close();
writeStream.Close();
}
To call this method, just do something like this:

string saveTo = "some path to save"
// create a write stream
FileStream writeStream = new FileStream(saveTo, FileMode.Create, FileAccess.Write);
// write to the stream
ReadWriteStream(readStream,writeStream);
