IContractBehaviorAttribute.TargetContract IContractBehaviorAttribute.TargetContract IContractBehaviorAttribute.TargetContract IContractBehaviorAttribute.TargetContract Property

Definition

Gets the type of the contract to which the contract behavior is applicable.

public:
 property Type ^ TargetContract { Type ^ get(); };
public Type TargetContract { get; }
member this.TargetContract : Type
Public ReadOnly Property TargetContract As Type
Property Value

The contract to which the contract behavior is applicable.

Examples

The following code example assumes a custom System.ServiceModel.Dispatcher.IInstanceProvider implementation called ObjectProviderBehavior that provides a "singleton" behavior; it always returns the same service instance and does not recycle it.

To insert the instance provider customization, the example shows how to implement a custom attribute (SingletonBehaviorAttribute) that implements System.ServiceModel.Description.IContractBehavior to insert the custom service instance provider. It also implements IContractBehaviorAttribute, which binds its application to the ISampleService contract.

public class SingletonBehaviorAttribute : Attribute, IContractBehaviorAttribute, IContractBehavior
{

  #region IContractBehaviorAttribute Members

  public Type TargetContract
  {
    get { return typeof(ISampleService); }
  }

  #endregion

  #region IContractBehavior Members

  public void AddBindingParameters(ContractDescription description, ServiceEndpoint endpoint, System.ServiceModel.Channels.BindingParameterCollection parameters)
  {
    return;
  }

  public void ApplyClientBehavior(ContractDescription description, ServiceEndpoint endpoint, ClientRuntime clientRuntime)
  {
    return;
  }

  public void ApplyDispatchBehavior(ContractDescription description, ServiceEndpoint endpoint, DispatchRuntime dispatch)
  {
    dispatch.InstanceProvider = new ObjectProviderBehavior("Custom ObjectProviderBehavior constructor.");
  }

  public void Validate(ContractDescription description, ServiceEndpoint endpoint)
  {
    return;
  }

  #endregion
}
 Public Class SingletonBehaviorAttribute
  Inherits Attribute
  Implements IContractBehaviorAttribute, IContractBehavior

#Region "IContractBehaviorAttribute Members"

Public ReadOnly Property TargetContract() As Type Implements IContractBehaviorAttribute.TargetContract
  Get
	  Return GetType(ISampleService)
  End Get
End Property

#End Region

#Region "IContractBehavior Members"

Public Sub AddBindingParameters(ByVal description As ContractDescription, ByVal endpoint As ServiceEndpoint, ByVal parameters As System.ServiceModel.Channels.BindingParameterCollection) Implements IContractBehavior.AddBindingParameters
  Return
End Sub

Public Sub ApplyClientBehavior(ByVal description As ContractDescription, ByVal endpoint As ServiceEndpoint, ByVal clientRuntime As ClientRuntime) Implements IContractBehavior.ApplyClientBehavior
  Return
End Sub

Public Sub ApplyDispatchBehavior(ByVal description As ContractDescription, ByVal endpoint As ServiceEndpoint, ByVal dispatch As DispatchRuntime) Implements IContractBehavior.ApplyDispatchBehavior
  dispatch.InstanceProvider = New ObjectProviderBehavior("Custom ObjectProviderBehavior constructor.")
End Sub

Public Sub Validate(ByVal description As ContractDescription, ByVal endpoint As ServiceEndpoint) Implements IContractBehavior.Validate
  Return
End Sub

#End Region
 End Class

Remarks

Implement the TargetContract property to specify the contract to which the contract behavior is applied when the implementing System.ServiceModel.Description.IContractBehavior attribute is applied to a service class.
