Approach and example of serialization functions limitations

Approach to serialization LimitFunction

Class Function implements the interface ISerializable. Therefore, for functions of limited available as SOAP and binary serialization.

It is recommended to use library tools ICSSoft.STORMNET.Tools.XmlTools instead of a direct appeal to System.Runtime.Serialization.Formatters.Soap.SoapFormatter or System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.

In the specified library classes available:

• ToolXML - allows to serialize means SoapFormatter,
• ToolBinarySerializer - allows to serialize means BinaryFormatter.

Example comparing binary and SOAP serialization LimitFunction

Binary form serialization is more productive and the rows get shorter.
