Hello Everyone,

I have used following code to validate my password

C#

@"^[A-Z]{1}[a-z]+$"

Can anyone suggest changes ,I wish to include @ in my passwords

For name validation I have used

C#

"^[A-Z][a-zA-Z]*$")

I want to restrict entries like hsgetgsbs bhbahabb @hahaaj and so on.Can this be achieved with Regular expressions?.I want to achieve the same in fields like First Name Last Name and Username

For a 10 digit mobile number I used following

C#

@"^[1-9]\d{2}-[1-9]\d{2}-\d{4}$"

but didn't work.Can anyone suggest changes?

Thanks

Solution 1

Password including "@":

@"^[A-Z]{1}[a-z@]+$"

The others we can't help with as we have no idea what restrictions you are tying to apply, and absolutely no idea what "didn't work" is supposed to mean...

Thanks for replying Original Griff

I mean for Name Validation I used "^[A-Z][a-zA-Z]*$").Here I want to restrict entries like agavvsgsb or any other junk entry in Name Field.Is that possible to achieve?

In case of Phone Validation I used Regex @"^[1-9]\d{2}-[1-9]\d{2}-\d{4}$".I tried adding 10 digit mobile number but its not working.Please suggest changes to the regex so that I can add 10 digit Mobile number

Thanks

The problem is that "entries like agavvsgsb or any other junk entry" is not anything a regrex can check. Is "Lloyd" meaningful? It's a valid name, as is "Vivek", or "Griff".
You can't check meaning with regexes - just text sequences.

And "it's not working" could mean anything!
