Form to SQL Helper Class?

Hi does anyone have a helper class for converting Request.Form values to a suitable SQL value or system value? I'm posting a a function in a seperate thread I find useful in the interest of code sharing.

Right now I have a simple information class and I am using reflection to get all it's properties. Then I am looping thru the form keys, and setting any matches. I am getting an error because drop downs are listed in the form keys array even if no value was selected. So I want some kind of function that accepts (object, system.type) and makes sure the object value in an acceptable value for the given type. i.e. "" goes to "0" for an integer, "on" goes to "true" for a checkbox boolean.

VB Code:

Public Sub LoadInfoFromRequest(ByRef myInfo As MyInfoBase)
 
 
        Dim f As System.Reflection.FieldInfo
        Dim x As Integer
        Dim o As Object
        Dim n, t As String
        Dim FormKeys() As String
 
        'Use reflection to get the fields
        Dim myFieldInfo() As System.Reflection.FieldInfo
        myFieldInfo = myInfo.GetType().GetFields()
 
        'Load the object from the datarow.
        FormKeys = HttpContext.Current.Request.Form.AllKeys
        For Each f In myFieldInfo
            x = FormKeys.IndexOf(FormKeys, f.Name)
            If x >= 0 Then
                n = f.Name
                t = f.GetType().ToString
                o = HttpContext.Current.Request.Form(f.Name)
                'I need some function here like ConvertObjectValue( object, system.type)
                f.SetValue(myInfo, o)
            End If
        Next
 
    End Sub

Thanks,
