示例1: CalculatePrimeAsync
// This method starts an asynchronous calculation.
// First, it checks the supplied task ID for uniqueness.
// If taskId is unique, it creates a new WorkerEventHandler
// and calls its BeginInvoke method to start the calculation.
public virtual void CalculatePrimeAsync(
int numberToTest,
object taskId)
{
// Create an AsyncOperation for taskId.
AsyncOperation asyncOp =
AsyncOperationManager.CreateOperation(taskId);
// Multiple threads will access the task dictionary,
// so it must be locked to serialize access.
lock (userStateToLifetime.SyncRoot)
{
if (userStateToLifetime.Contains(taskId))
{
throw new ArgumentException(
"Task ID parameter must be unique",
"taskId");
}
userStateToLifetime[taskId] = asyncOp;
}
// Start the asynchronous operation.
WorkerEventHandler workerDelegate = new WorkerEventHandler(CalculateWorker);
workerDelegate.BeginInvoke(
numberToTest,
asyncOp,
null,
null);
