"fantancistics" sounds like a fantastic STD.

Solution 1

That's trivial:

\d{10}

If you are going to play with Regexes, then get a copy of Expresso[^] - it's free, and it examines and generates Regular expressions.

Dim text As String = " Hey guys, I recently brought this bike from jaipur cutomer 8547582496 honda showroom.after documentation process, I drove my home that is approximately 8 km away from that store and engine and silencer get heated terribly.I thought it may be due to first drive.Next day after a ride of 8 km it "
Dim pattern As String = "/^\d{10}$/"
If Regex.IsMatch(review, pattern) Then
Return False
End If

Not working

Of course it isn't working.
You added "start of line or string" and "end of line or string" to the match I gave you, which means that the requirement becomes "the whole string must be just ten digits and nothing else". Since there is other stuff in there, it doesn't match ...

Seriously, get a copy of Expresso - it would have explained that to you ...

And?
What have you tried?
Where are you stuck?
What help do you need?

above validation failed when i 78459&*#$@$$<><85 this number , i want this also be cheked and also it failed in "1656646646 avsnns absbs abss", i want both condition to be cheked

At the risk of repeating myself:
"And?
What have you tried?
Where are you stuck?
What help do you need?"

You want to try answering some - or preferably all - of those questions?

i want this validation 78459&*#$@$$<><85 this number , i want this also be cheked and also it failed in "1656646646 avsnns absbs abss", i want both condition to be cheked

i tired \d{10}

this validate only 10 number from string e.g 5695748596

i want expression that validate number and special charater between them e.g 25564@$55464

"I want", "I want", "I want" ...
What have *you* tried, other than a regex to solve a different problem?

You've asked 32 questions now, and they are all the same: "I want" with little or no sign of effort or willingness to learn coming from you. That's characteristic of a "Help Vampire" rather than somebody who is trying to improve. Honestly? You will get a faster result by learning some of this stuff yourself instead of expecting others to do it for you.

So I repeat myself again:
"And?
What have you tried?
Where are you stuck?
What help do you need?"
And this time, try to solve it first - and then ask for help.

As OG already answered: \d{10}

Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:
perlre - perldoc.perl.org[^]
Here is links to tools to help build RegEx and debug them:
.NET Regex Tester - Regex Storm[^]
Expresso Regular Expression Tool[^]
RegExr: Learn, Build, & Test RegEx[^]
Online regex tester and debugger: PHP, PCRE, Python, Golang and JavaScript[^]
This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx: Debuggex: Online visual regex tester. JavaScript, Python, and PCRE.[^]
This site also show the Regex in a nice graph but can't test what match the RegEx: Regexper[^]

[Update]
If you read carefully the RegExs, you will see that /^\d{10}$/ and \d{10} are different and thus match different strings. Read documentation to understand what is the difference.
