Question

A requirement for an ASP.Net 2.0 project I’m working on limits a certain field to a max of 10 words (not characters). I’m currently using a CustomValidator control with the following ServerValidate method:

Protected Sub TenWordsTextBoxValidator_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles TenWordsTextBoxValidator.ServerValidate     '' 10 words     args.IsValid = args.Value.Split(' ').Length <= 10 End Sub 

Does anyone have a more thorough/accurate method of getting a word count?

Answer 1

This regex seems to be working great:

'^(\b\S+\b\s*){0,10}$' 

Update: the above had a few flaws so I ended up using this RegEx:

[\s\x21-\x2F\x3A-\x40\x5B-\x60\x7B-\xBF]+ 

I split() the string on that regex and use the length of the resulting array to get the correct word count.
