Handle Class

.NET Framework (current version)
 

Represents a type that has its lifetime controlled by the workflow runtime.

Namespace:   System.Activities
Assembly:  System.Activities (in System.Activities.dll)


[DataContractAttribute]
public abstract class Handle

NameDescription
System_CAPS_protmethodHandle()

Initializes a new instance of the Handle class.

NameDescription
System_CAPS_pubpropertyExecutionPropertyName

Gets the name to be used by this Handle when added to an activity’s execution properties.

System_CAPS_pubpropertyOwner

Gets the ActivityInstance that contains the Variable that contains the Handle.

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_protmethodOnInitialize(HandleInitializationContext)

Called by the workflow runtime when the environment that contains the Handle is initialized.

System_CAPS_protmethodOnUninitialize(HandleInitializationContext)

Called by the workflow runtime when the Variable for the Handle goes out of scope.

System_CAPS_protmethodThrowIfUninitialized()

Throws an InvalidOperationException if the Handle has not been initialized.

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

Types derived from Handle have their lifetimes controlled by the workflow runtime. For workflow variables of handle types, the runtime uses the required default constructor to create an instance of the type, assigns it to the Variable, and calls OnInitialize when initializing the environment. When the variable goes out of scope, OnUninitialize is called.
