Examples

The following code example shows how to asynchronously request the cancellation of a disk repair operation:

try
{
   StorageManager storageManager = new StorageManager();
   storageManager.Connect();
}
catch (StorageObjectModelException stoEx)
{
   //Handle exception
} 

DiskSet diskSet = storageManager.DiskSets.FirstOrDefault(currDiskSet => 
   currDiskSet.CurrentStatus == DiskSetStatus.Repairing);
if (diskSet == null)
{
   Console.WriteLine("No diskset in repairing state found");
}
else
{
   CancelOperationRequest cancelOperationRequest = diskSet.GetCancelRepairRequest();
   try
   {
      cancelOperationRequest.PropertyChanged += 
         cancelOperationRequest_PropertyChanged;
      cancelOperationRequest.CancelOperationAsync();
   }
   catch (StorageObjectModelException stoEx)
   {
      Console.WriteLine("Exception: {0}. Error Code: {1}", 
         stoEx.Message, stoEx.ErrorCode);
   }
}

The following code example shows the request delegate method:

private void cancelOperationRequest_PropertyChanged(
   object obj, PropertyChangedEventArgs args)
{
   CancelOperationRequest cancelOperationRequest = 
      (CancelOperationRequest)obj;
   if(cancelOperationRequest.Status == OperationStatus.Succeeded)
   {
      Console.WriteLine("Request completed successfully");
   }
   else if (cancelOperationRequest.Status == OperationStatus.Failed)
   {
      Console.WriteLine("Request failed: {0}. Error Code: {1}", 
         cancelOperationRequest.ErrorMessage, 
         cancelOperationRequest.ErrorCode);
   }
}
