1. Make you changes like below while building your html via StringBuilder like

   StringBuilder sb = new StringBuilder(); sb.Append(""); sb.Append("");

   foreach (DataColumn column in dt.Columns) { sb.Append(""); sb.Append(column.ColumnName); sb.Append(""); } sb.Append(""); foreach (DataRow row in dt.Rows) { sb.Append(""); foreach (DataColumn column in dt.Columns) { sb.Append(""); sb.Append(row[column]); sb.Append(""); } sb.Append(""); } sb.Append("");

2. Use XMLWorkerHelper instead of HTMLWorker because now HTMLWorker is deprecated. ans not more support by iTextSharp. like

   PdfWriter writer = PdfWriter.GetInstance(pdfDoc, memoryStream); pdfDoc.Open(); XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr); pdfDoc.Close(); byte[] bytes = memoryStream.ToArray(); memoryStream.Close();
