Generic Dictionary Mapper for Critiques

Posted 06 December 2012 - 12:23 PM

Submitting this for review to try to weed out *obvious* or sneaky errors I don't address or even just to see if the whole thing is redundant and already exists in the framework.

Otherwise, if you need to use it: enjoy.

    Public Class DictionaryMapper(Of T As {Class, New})
        Public Shared Function MapDictionaryToObject(ByVal entity As T, ByVal dictionary As IDictionary) As T
            Dim properties = entity.GetType().GetProperties()

            For Each pInfo As System.Reflection.PropertyInfo In properties
                If dictionary.Contains(pInfo.Name) Then
                    Dim infoType = pInfo.PropertyType
                    Dim nullableType = Nullable.GetUnderlyingType(pInfo.PropertyType)

                    If Not nullableType Is Nothing Then
                        infoType = nullableType
                    End If

                    Dim conversion = Convert.ChangeType(dictionary(pInfo.Name), infoType)

                    pInfo.SetValue(entity, conversion, Nothing)
                End If
            Next

            Return entity
        End Function
    End Class
