I'm trying to build a LINQ expression that will use a dynamic construction
of a LIKE statement in the WHERE clause, it would look something like this
in SQL:

WHERE TaskGroup Like "*00*" OR TaskGroup Like "*20*"

It would be many variations on the above.

I know how use the LIKE clause in LINQ but not in this context, here is an
attempt that did not work, I also tried building it into a variable that
looked like the LINQ LIKE clause if I were to type it out (WHERE filterExp)
but it did not work either.

Thanks for any input

filterExp = ""

       i = InStr(1, strFilter, ":")

       Do Until i = 0

           filterExp = filterExp & """Like *" & Mid(strFilter, i - 2, 2) &
"*"""

           i = InStr(i + 1, strFilter, ":")

           If i <> 0 Then

               filterExp = filterExp + ", "

           End If

       Loop

       Dim grp As String() = {filterExp}

       Dim dbTask As New DataTaskDataContext

       Dim taskTbl = From tas In dbTask.tblTasks _

                     Where grp.Contains(tas.TaskGroup) _

                     Select tas
