10 Oct

Here is a quick Extension Method that you can use to generate a friendly string for use in a URL.

Function ToFriendlyUrl(txt As String, Optional maxLength As Integer = 45) As String
If String.IsNullOrWhiteSpace(txt) Then

Return String.Empty
Dim str As String = RemoveAccent(txt).ToLower()

str = RegularExpressions.Regex.Replace(str, "[^a-z0-9\s-]", String.Empty)
str = RegularExpressions.Regex.Replace(str, "\s+", " ").Trim()
str = str.Substring(0, If(str.Length str = RegularExpressions.Regex.Replace(str, "\s", "-")

Return str

End If

End Function
