Represents a type that has its lifetime controlled by the workflow runtime.
Assembly: System.Activities (in System.Activities.dll)
Thetype exposes the following members.
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (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.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|OnInitialize||Called by the workflow runtime when the environment that contains the is initialized.|
|OnUninitialize||Called by the workflow runtime when the Variable for the goes out of scope.|
|ThrowIfUninitialized||Throws an InvalidOperationException if the has not been initialized.|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
Types derived from 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(HandleInitializationContext) when initializing the environment. When the variable goes out of scope, OnUninitialize(HandleInitializationContext) is called.
