ParameterCollection.GetValues Method (HttpContext, Control)
Gets an ordered collection of Parameter object names and their corresponding values currently contained by the collection.
Assembly: System.Web (in System.Web.dll)
Because the IOrderedDictionary object must have uniquely named entries but the ParameterCollection collection does not require or guarantee unique Parameter object names, the implementation of this method appends a number to the end of each Name property to ensure uniqueness in the returned collection.
