ASP.NET - problem with iTextSharp on IIS...

Hi,

I am working in ASP.Net 2008 using C# and somewhere in my project I need to extract text from a PDF file and store it into a text file.

I use the folowing code by adding a reference of iTextsharp dll.

This code works fine in dot net, but not working on IIS. Can any one tell me what is wrong here. Please I m in need indee

protected void Button1_Click(object sender, EventArgs e)

String file = @"D:\Munendra\Personal\Stevens CVAT.pdf";

if (!File.Exists(file))

file = Path.GetFullPath(file);

if (!File.Exists(file))

Console.WriteLine("Please give in the path to the PDF file.");

ExtractText(file, "C:\\" + Path.GetFileNameWithoutExtension(file) + ".txt");

public bool ExtractText(string inFileName, string outFileName)

arrCheck = new ArrayList();

StreamWriter outFile = null;

try

// Create a reader for the given PDF file

PdfReader reader = new PdfReader(inFileName);

outFile = new StreamWriter(outFileName, false, System.Text.Encoding.UTF8);

for (int page = 1; page <= reader.NumberOfPages; page++)

String Text = "";

Text = ExtractTextFromPDFBytes(reader.GetPageContent(page)) + " ";

Text = Text.Replace("\r", "");

String[] split = Text.Split('\n');

for (int iCount = 0; iCount < split.Length; iCount++)

Response.Write("Success");

return true;

catch

{ return false; }

finally

{ if (outFile != null) outFile.Close(); }

private string ExtractTextFromPDFBytes(byte[] input)

if (input == null || input.Length == 0) return "";

try

string resultString = "";

bool inTextObject = false;

bool nextLiteral = false;

int bracketDepth = 0;

char[] previousCharacters = new char[_numberOfCharsToKeep];

for (int j = 0; j < _numberOfCharsToKeep; j++) previousCharacters[j] = ' ';

for (int i = 0; i < input.Length; i++)

char c = (char)input[i];

if (inTextObject)

if (bracketDepth == 0)

if (CheckToken(new string[] { "TD", "Td" }, previousCharacters))

resultString += "\n\r";

else

if (CheckToken(new string[] { "'", "T*", "\"" }, previousCharacters))

resultString += "\n";

else

if (CheckToken(new string[] { "Tj" }, previousCharacters))

resultString += " ";

// End of a text object, also go to a new line.

if (bracketDepth == 0 && CheckToken(new string[] { "ET" }, previousCharacters))

inTextObject = false;

resultString += " ";

else

{// Start outputting text

if ((c == '(') && (bracketDepth == 0) && (!nextLiteral))

else

{// Stop outputting text

if ((c == ')') && (bracketDepth == 1) && (!nextLiteral))

else

{// Just a normal text character:

if (bracketDepth == 1)

if (c == '\\' && !nextLiteral)

nextLiteral = true;

else

if (((c >= ' ') && (c <= '~')) || ((c >= 128) && (c < 255)))

nextLiteral = false;

for (int j = 0; j < _numberOfCharsToKeep - 1; j++)

// Start of a text object

if (!inTextObject && CheckToken(new string[] { "BT" }, previousCharacters))

inTextObject = true;

return resultString;

catch

{ return ""; }

private bool CheckToken(string[] tokens, char[] recent)

foreach (string token in tokens)

if ((recent[_numberOfCharsToKeep - 3] == token[0]) &&

((recent[_numberOfCharsToKeep - 1] == ' ') ||

((recent[_numberOfCharsToKeep - 4] == ' ') ||

return true;

return false;
