Examples
The following code example demonstrates how to use a CorrelationParameterAttribute for an ExternalDataExchange interface. This code example is from the CorrelatedLocalService SDK sample. For more information, see Correlated Local Service Sample.
[ExternalDataExchange]
[CorrelationParameter("taskId")]
public interface ITaskService
{
[CorrelationInitializer]
void CreateTask(string taskId, string assignee, string text);
[CorrelationAlias("taskId", "e.Id")]
event EventHandler<TaskEventArgs> TaskCompleted;
}

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.
Default setting; can be overridden by the CorrelationAliasAttribute.
Constructors
CorrelationParameterAttribute(String) |
Initializes a new instance of the CorrelationParameterAttribute where the name of the parameter is used for correlation. |
Properties
Name |
Gets the name of the parameter used for correlation. |
TypeId |
When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute) |
Methods
Equals(Object) |
Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute) |
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(Object) |
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) |
Explicit Interface Implementations
_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr) |
Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute) |
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr) |
Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute) |
_Attribute.GetTypeInfoCount(UInt32) |
Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute) |
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr) |
Provides access to properties and methods exposed by an object. (Inherited from Attribute) |
