MessageContractMemberAttribute MessageContractMemberAttribute MessageContractMemberAttribute MessageContractMemberAttribute Class

Examples

The following code examples demonstrate a custom message contract that uses the MessageContractAttribute, MessageHeaderAttribute, and MessageBodyMemberAttribute attributes (which all inherit from MessageContractMemberAttribute) to create custom typed messages to use in operations. In this case, there are three members that are serialized into the body element of the SOAP message: sourceAccount, targetAccount, and the amount value, (which is serialized into an element with the name transactionAmount). In addition, the IsAudited SOAP header element resides in the http://schemas.contosobank.com/auditing/2005 namespace, and sourceAccount is encrypted and digitally signed.

Note

The Operation and Account types must have a data contract.

[MessageContract]  
public class BankingTransaction  
{  
  [MessageHeader]   
  public Operation operation;  
  [MessageHeader(Namespace="http://schemas.contosobank.com/auditing/2005")]   
  public bool IsAudited;  
  [MessageBody(ProtectionLevel=ProtectionLevel.EncryptAndSign)]   
  public Account sourceAccount;  
  [MessageBody]   
  public Account targetAccount;  
  [MessageBody(Name="transactionAmount")]   
  public int amount;  

Remarks

This class contains properties common to all parts of a SOAP message. For example, all parts have a name and a namespace, and potentially a level of security applied.

For information on controlling the serialization of the contents of a SOAP body without modifying the default SOAP envelope itself, see System.Runtime.Serialization.DataContractAttribute, Specifying Data Transfer in Service Contracts, and Using Data Contracts.

For more information about creating message contracts, see Using Message Contracts.
