Unable to replace string

[bhaavan (bhaavan kishore)]

Hello Team,
Actually I am trying to automate captcha. Everything is going good,but when I am taking text from web application instead of “1” , I am getting character “I” .
I used mentioned regular expression for replacing
“System.Text.RegularExpressions.Regex.Replace(value,“I”, “1”)”
but no luck it is only working at times.
Please help me to solve this issue

@bhaavan

“System.Text.RegularExpressions.Regex.Replace(value,“I”, “1”)”

this should work actually
kindly try with this expression
value.ToString.Replace(“|”,“1”)

Cheers @bhaavan

OCR activities are unreliable specially in case of captcha code…
I will recommend you to fine tune your OCR activity to give correct result instead of replacing text in result.
For example… for number “1”, an unreliable OCR can give you 1 or l (lower case L) or I (upper case i ) or even | (pipe)…
