ReceiveReply Class
An activity that receives a message as part of a request/reply message exchange pattern.
Namespace: System.ServiceModel.Activities
Assembly: System.ServiceModel.Activities (in System.ServiceModel.Activities.dll)
The ReceiveReply type exposes the following members.
| Name | Description | |
|---|---|---|
 | Action | Gets or sets the value of the action header of the message. |
| CacheId | Gets the identifier of the cache that is unique within the scope of the workflow definition. (Inherited from Activity.) |
| Content | Gets or sets the content received by the ReceiveReply activity |
| CorrelationInitializers | Gets a collection of correlation initializers. |
| DisplayName | Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking. (Inherited from Activity.) |
| Id | Gets an identifier that is unique in the scope of the workflow definition. (Inherited from Activity.) |
| ImplementationVersion | Gets or sets the version of the implementation used. (Inherited from Activity.) |
| Request | Gets or sets a reference to the Send activity paired with this ReceiveReply activity. |
| Name | Description | |
|---|---|---|
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| ShouldSerializeDisplayName | Indicates whether the DisplayName property should be serialized. (Inherited from Activity.) |
| ToString | Returns a String that contains the Id and DisplayName of the Activity. (Inherited from Activity.) |
The following example shows how to use a ReceiveReply activity. A Send activity is created and added to a Sequence. A ReceiveReply activity is then added to the Sequence to receive the reply from the Send activity.
static void CreateClientWorkflow()
{
Variable<string> message = new Variable<string>("message", "Hello!");
Variable<string> result = new Variable<string> { Name = "result" };
Endpoint endpoint = new Endpoint
{
AddressUri = new Uri(Microsoft.Samples.WorkflowServicesSamples.Common.Constants.ServiceBaseAddress), Binding = new BasicHttpBinding(),
};
Send requestEcho = new Send
{
ServiceContractName = XName.Get("Echo", "http://tempuri.org/"),
Endpoint = endpoint,
OperationName = "Echo",
//parameters for send
Content = new SendParametersContent
{
Parameters =
{
{ "message", new InArgument<string>(message) }
}
}
};
workflow = new CorrelationScope
{
Body = new Sequence
{
Variables = { message, result },
Activities =
{
new WriteLine {
Text = new InArgument<string>("Client is ready!")
},
requestEcho,
new WriteLine {
Text = new InArgument<string>("Message sent: Hello!")
},
new ReceiveReply
{
Request = requestEcho,
//parameters for the reply
Content = new ReceiveParametersContent
{
Parameters =
{
{ "echo", new OutArgument<string>(result) }
}
}
},
new WriteLine {
Text = new InArgument<string>(env => "Message received: "+result.Get(env))
}
}
}
};
}
