 dynamicDotNetTwainThum.IfShowCancelDialogWhenBarcodeOrOCR = < span class =code-keyword> true ; 
 dynamicDotNetTwainThum.OCRResultFormat = Dynamsoft.DotNet.TWAIN.OCR.ResultFormat.Text; 
 dynamicDotNetTwainThum.OCRLanguage =   eng; 
  byte  [] bytes = dynamicDotNetTwainThum.OCR（dynamicDotNetTwainThum.CurrentSelectedImageIndicesInBuffer）;  //  识别缓冲图像 
 如果（bytes！=  null ）
 {
 SaveFileDialog dlg =  new  SaveFileDialog（）; 
 dlg.Filter =  文本文件（* .txt）| * .txt; 
  if （dlg.ShowDialog（）。Value）
 {
 System.IO.File.WriteAllBytes（dlg.FileName，bytes） ）;  //  将已识别的文字写入文本文件 
} 
} 

I am trying to implement the OCR Software using the C#; I'm new in this field;
Can any body tell me how to make use of Tesseract OCR Engine in C#?

This post introduces an easy way to write OCR program in C#.
http://www.codepool.biz/ocr-barcode-twain/twain-sdk/have-fun-with-the-wpf-demo-of-net-twain-5-0.html[^]

dynamicDotNetTwainThum.IfShowCancelDialogWhenBarcodeOrOCR = true;
dynamicDotNetTwainThum.OCRResultFormat = Dynamsoft.DotNet.TWAIN.OCR.ResultFormat.Text;
dynamicDotNetTwainThum.OCRLanguage = "eng";
byte[] bytes = dynamicDotNetTwainThum.OCR(dynamicDotNetTwainThum.CurrentSelectedImageIndicesInBuffer); // recognize the buffered image
if (bytes != null)
{
   SaveFileDialog dlg = new SaveFileDialog();
   dlg.Filter = "Text File(*.txt)|*.txt";
   if (dlg.ShowDialog().Value)
   {
      System.IO.File.WriteAllBytes(dlg.FileName, bytes); // write recognized text to text file
   }
}
