Question

I have to create a class in Visual Basic called StringWork.

Public Class StringWork

Now i wrote a shared function in the class called Working that can take a string or a string and Boolean.

Public Shared Function Working(ByVal SingleString as string, optional BValu  as Boolean = true)as string
    if(working(SingleString))then
    'The handling of the string
    else if (working(SingleValue, BValue) then
    'do something else with string 
    end if
end function

The function I wrote is returning a string.
Can I access the string passed and edit characters in the string or change the position of characters?

Answer 1

You use that optional parameter to determine how you handle that string:

Public Shared Function Working(ByVal singleString as string, _
                               Optional bValue as Boolean = True) As String
  If bValue Then
    'Handle the true part manipulating the result string
  Else
    'Handle the false part manipulating the result string
  End If

End Function

If you call this function like this:

Dim test As String = StringWork.Working("I am Spartacus")

it will call that Working function with bValue = true.

What bValue is suppose to represent isn’t very clear from the code nor the post.
