This post does not even define the problem. What is one number is 10 digit, and another one is not?
More importantly, What have you tried so far?
What is the problem you face here?

No, you need something different: using your own brain, thinking. You go correct answer, now think how to apply it to validation.
Otherwise no solutions could ever help you.

Hi Sergey Alexandrovich Kryukov,i just want to know how to do this in another way.sorry,i didn't get another idea.If you know then please explain the logic how to do this.It will help me in future to do this in different way. Thanks and sorry if i said anything wrong.

Sergey Alexandrovich Kryukov 22-Feb-14 0:27am

The logic: you split the string by ',' (or any other array of delimiters). It will give you array of string, each representing a slice of your source string. In a loop, for each string of this array, check string.Length == 10.
Is it all clear?

Really thanks for the quick reply.but if we get value in string instead of string array then how can we do this.if i understood wrong please explain bit more or post some links regarding this.Sorry i don't know how to ask in english clearly to ask my doubts

Sergey Alexandrovich Kryukov 22-Feb-14 0:54am

I don't understand what is your concern. I cannot imagine anything simpler than that. Perhaps, just write it in code; and you will see how it works out.

Tom Marvolo Riddle 22-Feb-14 0:52am

but in this way we have to split the string.am i right?

Sergey Alexandrovich Kryukov 22-Feb-14 0:55am

Yes. Why not?

Tom Marvolo Riddle 22-Feb-14 0:59am

Now i understand clearly.Thanks a lot for spending time to clear my doubts.I don't know english well.For me, it takes time to understand what said in engish.once again thanks a lot

Sergey Alexandrovich Kryukov 22-Feb-14 1:15am

I must admit your writing English is clear enough and nearly correct.
(Please also take care of your punctuation and capitalization, which is not related to English: not "english well.For me...", but "English well. For me...", not important blank space after '.'. Otherwise it's hard to read.
Good luck.

Solution 3

Try this:

C#

TextBox1.Text = "9856321470,123564780,9847562155,956325698,8452136547"

Dim text As String() = TextBox1.Text.Split(","C)

For i As Integer = 0 To text.Length - 1

	If text(i).Length = 10 Then
			
	ElseIf text(i).Length <> 10 Then
        //error message here
	End If
Next
