The DataContractSerializer sample demonstrates the DataContractSerializerwhich performs general serialization and deserialization services for the data contract classes. The sample creates a Record object, serializes it to a memory stream and deserializes the memory stream back to another Record object to demonstrate the use datacontractserializer binary writer the DataContractSerializer.

The sample then serializes the Record object using a binary writer to demonstrate how the writer affects serialization. The setup procedure and build instructions for this sample are located at the end of this topic.

The sample code creates a Record object named record1 then displays the object. The sample then uses the DataContractSerializer datacontractserializer binary writer serialize record1 into datacontractserializer binary writer memory stream. Next, the sample uses the DataContractSerializer to deserialize the memory stream back into a new Record object and displays it. However, you can influence the encoding of the XML by passing in a different writer.

The sample creates a binary writer by calling CreateBinaryWriter. It then passes the writer and the record object to the serializer when it calls WriteObjectContent. Finally, datacontractserializer binary writer sample flushes the writer and reports on the length of the streams.

When you run the sample, the original record and the deserialized record are displayed, followed by the comparison between the length of the text datacontractserializer binary writer and the binary encoding. To build the C or Visual Basic. The samples may already be installed on your machine. Check for the following default directory before continuing. This sample is located in the following directory.
