Hi,

First browse the resume next click on scan button then that uploaded file data is came into the text box, now from that text box data i want to scan the first name ,middle name and last name.
I am using the following code to split the input after splitting using validation to identify the fields in the input text like email,phone number..... .In the same way how can i identify the first name, middle name and last name from uploaded resume text.    

Plz send me the appropriate code as early as possible in asp.net using C#.
