PersistenceProvider::BeginDelete Method (Object^, TimeSpan, AsyncCallback^, Object^)

 

When implemented in a derived class, represents the beginning of the Delete phase. The Delete phase occurs when service state data is permanently deleted from the persistence store.

Namespace:   System.ServiceModel.Persistence
Assembly:  System.WorkflowServices (in System.WorkflowServices.dll)

public:
virtual IAsyncResult^ BeginDelete(
	Object^ instance,
	TimeSpan timeout,
	AsyncCallback^ callback,
	Object^ state
) abstract

Parameters

instance
Type: System::Object^

The actual instance state.

timeout
Type: System::TimeSpan

The time period after which the persistence provider aborts this attempt.

callback
Type: System::AsyncCallback^

The method to be called when the operation is completed.

state
Type: System::Object^

A user-provided object that distinguishes this particular asynchronous operation from other operations.

Return Value

Type: System::IAsyncResult^

The state of the BeginDelete asynchronous method call.

The following code demonstrates how to implement the BeginDelete method. This code example is part of the DurableServiceFactory SDK sample from the FilePersistenceProviderFactory.cs file. For more information, seethe DurableServiceFactory SDK sample.

public override IAsyncResult BeginDelete(object instance, TimeSpan timeout, AsyncCallback callback, object state)
{
    base.ThrowIfDisposedOrNotOpen();
    return this.factory.BeginDelete(this.Id, timeout, callback, state);
}
