How to tell if field in file is boolean

[DangerMouse9]

I'm processing a file for input and need to verify that all fields are of the correct type. One of the types is boolean.
I've taken the input line and broke it down into a string array. From here I am checking whether the inputted value from the file is numeric and so on.
My problem is how can I check to see if the field that is suppose to be boolean really is boolean?

In the web controls there is a BaseCompareValidator that tests strings to see if they can convert to different types. You could either use that or I believe the you can get a TypeConverter object to check also.

You can also use error checking if you want but it will be slow the first time.

'syntax
        Dim obj As String = "2"
        MsgBox(CanConvertToBoolean(obj))
 
    Private Function CanConvertToBoolean(ByVal text As String) As Boolean
        Dim bln As Boolean
        Try
            bln = Boolean.Parse(text)
        Catch ex As Exception
            Return False
        End Try
        Return True
    End Function
