Constructors

VariableReference<T>()	Initializes a new instance of the VariableReference<T> class.
VariableReference<T>(Variable)	Initializes a new instance of the VariableReference<T> class using the specified variable.

Properties

CacheId	Gets the identifier of the cache that is unique within the scope of the workflow definition. (Inherited from Activity)
Constraints	Gets a collection of Constraint activities that can be configured to provide validation for the Activity. (Inherited from Activity)
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)
Implementation	Not supported. (Inherited from CodeActivity<TResult>)
ImplementationVersion	Gets or sets the implementation version of the activity. (Inherited from CodeActivity<TResult>)
LocationReference	Gets the variable reference of VariableReference<T>.
Result	Gets or sets the result argument for the Activity<TResult>. (Inherited from Activity<TResult>)
ResultType	When implemented in a derived class, gets the type of an activity OutArgument. (Inherited from ActivityWithResult)
Variable	Gets or sets the Variable represented by the VariableReference<T>.

Methods

CacheMetadata(ActivityMetadata)	Not implemented. Use CacheMetadata(CodeActivityMetadata) instead. (Inherited from CodeActivity<TResult>)
CacheMetadata(CodeActivityMetadata)	Creates and validates a description of the activity's arguments, variables, child activities, and activity delegates. (Inherited from EnvironmentLocationReference<T>)
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
Execute(CodeActivityContext)	Performs the execution of the activity. (Inherited from EnvironmentLocationReference<T>)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
OnCreateDynamicUpdateMap(UpdateMapMetadata, Activity)	Raises an event when creating a map for the dynamic update. (Inherited from CodeActivity<TResult>)
ShouldSerializeDisplayName()	Indicates whether the DisplayName property should be serialized. (Inherited from Activity)
ToString()	Returns a String representation of the VariableReference<T>.
