Assembly: System.ServiceModel (in System.ServiceModel.dll)
The MessageContractMemberAttribute type exposes the following members.
| Name | Description | |
|---|---|---|
|
MessageContractMemberAttribute | Initializes a new instance of the MessageContractMemberAttribute class. |
| Name | Description | |
|---|---|---|
|
HasProtectionLevel | When overridden in a derived class, gets a value that indicates whether the member has a protection level assigned. |
|
|
Name | Specifies the name of the element that corresponds to this member. |
|
|
Namespace | Specifies the namespace of the element that corresponds to this member. |
|
|
ProtectionLevel | Specifies whether the member is to be transmitted as-is, signed, or signed and encrypted. |
|
|
TypeId | When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.) |
| Name | Description | |
|---|---|---|
|
Equals | Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.) |
|
|
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|
|
GetHashCode | Returns the hash code for this instance. (Inherited from Attribute.) |
|
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
|
IsDefaultAttribute | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.) |
|
|
Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
|
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
|
ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
|
_Attribute.GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
|
|
_Attribute.GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
|
|
_Attribute.GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |
|
|
_Attribute.Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |
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 Data Contracts Overview.
For more information about creating message contracts, see Using Message Contracts.
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.

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;
