由tesseract创建时File.Exists为false

Question

I use tesseract to get text from captcha image. I use this code

Process p = new Process();
p.StartInfo.FileName = Server.MapPath("~/app/tesseract.exe");
p.StartInfo.Arguments = imgSavePath + " " + txtSavePath;
p.Start();
p.WaitForExit();
bool exist = File.Exists(txtSavePath);

The txtSavePath is created in windows explorer, i can open it and can read the text in it. But the exist variable is false . It is so strange. Can anybody tell me why? How can i use StreamReader to read text in created file?

Tesseract appends a ".txt" extension to the output text file; so in your case, it should be:

bool exist = File.Exists(txtSavePath + ".txt");
