vb.net utilizing ValueOption attributes

[tbayne]

I am having trouble utilizing a "ValueOption" attribute for a string: I am sure it is something simple I have failed to grasp.

Friend Class Options

    <[ValueOption(0)](Required:=True, HelpText:="File to process")>
    Public Property filename As String
    ......
End Class

This won't compile, and I ma not sure why. .Net 3.5.

I don't know VB.Net but the way you're defining your attribute is different from what I see here and here (see last example).

Here is an example of VB.Net code that should work.

Public Class Options
    <[Option]("exam-server", HelpText:="Exam server where exam being taken")>
    Public Property SpecifiedExamServer As Integer

    <[Option]("userid", HelpText:="UserID of Person Taking Exam", MutuallyExclusiveSet:="")>
    Public Property UserID As String

    <[Option]("examid", HelpText:="ID of exam to be taken", MutuallyExclusiveSet:="")>
    Public Property ExamID As String
End Class
