Simple regex example in VB.NET:

Imports System
Imports System.Text.RegularExpressions

Namespace DF1
     Public Class Program
         Public Shared Sub Main(args As String())
             Dim s As String = "bla bla bla 11-DEC-2018 bla bla bla 
12-DEC-2018 bla bla bla 13-DEC-2018 bla bla bla"
             For Each m As Match In Regex.Matches(s, 
"[0-9]{2}-[A-Z]{3}-[0-9]{4}")
                 Console.WriteLine(m.Value)
             Next
         End Sub
     End Class
End Namespace

Output:

11-DEC-2018
12-DEC-2018
13-DEC-2018
