How to Remoting Formatters

In .NET remoting, formatters are responsible for serializing and deserializing objects that are transmitted between the client and server. They facilitate the conversion of objects into a format that can be transmitted over the network and reconstructed back into objects at the receiving end.

There are two main types of formatters used in .NET remoting:

  1. Binary Formatter
  2. SOAP Formatter

Binary Formatter

The Binary Formatter is the default formatter used in .NET remoting. It serializes objects into a binary format that is compact and efficient for transmission over the network. The binary format is suitable for scenarios where performance and efficiency are critical. It preserves the internal structure of objects, including fields, properties, and type information.

SOAP Formatter

The SOAP (Simple Object Access Protocol) Formatter serializes objects into XML-based SOAP messages. This format is suitable for interoperability with other platforms and technologies that support SOAP. SOAP formatters generate XML representations of objects, which can be easily understood and processed by various systems. The SOAP format includes not only the object data but also additional metadata and type information.

The choice of formatter depends on the specific requirements of the application. Binary Formatter is often preferred for performance-critical scenarios within a homogeneous .NET environment, while SOAP Formatter is used when interoperability with other platforms or systems is essential.

Formatters can be configured at both the client and server sides using configuration files or programmatically. The appropriate formatter is selected based on the communication channel and the configuration settings specified in the application.


Remoting formatters play a crucial role in enabling the serialization and deserialization of objects, ensuring the seamless transmission and reconstruction of data between the client and server in a .NET remoting environment.
