/** @property */ public ProtectionLevel get_ProtectionLevel () /** @property */ public void set_ProtectionLevel (ProtectionLevel value)
public function get ProtectionLevel () : ProtectionLevel public function set ProtectionLevel (value : ProtectionLevel)
Property ValueOne of the ProtectionLevel values. The default is None.
The value is not one of the ProtectionLevel values.
Use the ProtectionLevel property to control whether the messages of an operation must be encrypted, signed, or both. The value set here is the default value for all messages specified for this operation unless a narrower scope overrides this value.
It is important to remember that the protection behavior at runtime is the combination of the protection-level values set on the following properties. These properties have a hierarchical structure. Setting the outermost value establishes the default setting for all narrower scopes unless a different value for a narrower scope is explicitly set. In this case, the outer value remains the default for all narrower scopes with the exception of that specifically set.
For example, if ServiceContractAttribute.ProtectionLevel is set to System.Net.Security.ProtectionLevel.EncryptAndSign and no other narrower scopes have protection level settings, all messages in an operation contract are encrypted and signed. If, however, one of those operations has the ProtectionLevel set to System.Net.Security.ProtectionLevel.Sign, then the messages for that operation are signed but all other messages in the contract are encrypted and signed.
For details about protection levels and their assumptions and scopes, see Understanding Protection Level.
The scopes at which these values are set are:
The MessageContractMemberAttribute.ProtectionLevel property on System.ServiceModel.MessageBodyMemberAttribute.
When there is no protection level explicitly specified on the contract and the underlying binding supports security (whether at the transport or message level), the effective protection level for the whole contract is System.Net.Security.ProtectionLevel.EncryptAndSign. If the binding does not support security (such as BasicHttpBinding), the effective System.Net.Security.ProtectionLevel is System.Net.Security.ProtectionLevel.None for the whole contract. The result is that depending upon the endpoint binding, clients can require different message or transport level security protection even when the contract specifies System.Net.Security.ProtectionLevel.None.
