Question

I am attempting to write a MVC model validation that verifies that there is 10 or more words in a string. The string is being populated correctly, so I did not include the HTML. I have done a fair bit of research, and it seems that something along the lines of what I have tries should work, but, for whatever reason, mine always seem to fail. Any ideas as to what I am doing wrong here?

(using System.ComponentModel.DataAnnotations, in a mvc 4 vb.net environment)

Have tried ([\w]+){10,}, ((\\S+)\s?){10,}, [\b]{20,}, [\w+\w?]{10,}, (\b(\w+?)\b){10,}, ([\w]+?\s){10}, ([\w]+?\s){9}[\w], ([\S]+\s){9}[\S], ([a-zA-Z0-9,.'":;$-]+\s+){10,} and several more varaiations on the same basic idea.

<Required(ErrorMessage:="The Description of Operations field is required"), RegularExpression("([\w]+){20,}", ErrorMessage:="ERROZ")>
Public Property DescOfOperations As String = String.Empty

Correct Solution was ([\S]+\s+){9}[\S\s]+

Answer 1

EDIT Moved accepted version to the top, removing unused versions. Unless I am wrong and the whole sequence needs to match, then something like (also accounting for double spaces):

([\S]+\s+){9}[\S\s]+

Or:

([\w]+?\s+){9}[\w]+
