BeginLoad Method

PersistenceProvider.BeginLoad Method

When implemented in a derived class, represents the beginning of the Load phase. The Load phase occurs when state data is loaded into the persistence provider from the persistence store.

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

public abstract IAsyncResult BeginLoad(
	TimeSpan timeout,
	AsyncCallback callback,
	Object state
)

Parameters

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 BeginLoad asynchronous method call.

The following code demonstrates how to implement the BeginLoad 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 BeginLoad(TimeSpan timeout, AsyncCallback callback, object state)
{
    base.ThrowIfDisposedOrNotOpen();
    return this.factory.BeginLoad(this.Id, timeout, callback, state);
}
