Prefix and postfix are used to additional explanation for error messages, like "About the uploaded excel file, ".

Type Parameters:

Parameters:

object - object to validate

addsItemNameToMessage - you'll get message with itemName when true is specified. It may be null, which is equal to false.

messagePrefix - Used when you want to put an additional message before the original message. It may be null, which means no messages added.

messagePostfix - Used when you want to put an additional message after the original message. It may be null, which means no messages added.

Returns:

MultipleAppException, may be null when no validation errors exist.
