从官网上下了资源文件，从上面的提示来看，程序运行时未找到"data.xml"，那么，"data.xml"应该放在哪呢？

一下是识别代码：
string resourceFilePath = Path.GetFullPath(Server.MapPath("./Lib/CharMap-Digits.zip"));
         // Source file: the file on which OCR will be performed.
         string imageFile = "20140407114743.jpg";

         // Initialize OcrEngine.
         OcrEngine ocr = new OcrEngine();
         // Set the image.
         ocr.Image = ImageStream.FromFile(filename);
         // Add language.
         ocr.Languages.AddLanguage(Language.Load("english"));
         // Load the resource file.
         using (ocr.Resource = new FileStream(resourceFilePath, FileMode.Open))
         {
            try
            {
                  // Process the whole image
                  if (ocr.Process())
                  {
                     // Get the complete recognized text found from the image
                     TextBox1.Text = ocr.Text.ToString();
                  }
            }
            catch (Exception ex)
            {
                  TextBox1.Text = "Exception: " + ex.ToString();
            }

         }
