Question

The Azure Table Storage .NET client received a complete redesign with SDK 1.8. With the new SDK, how can I check if a row exists?

Here’s an example from the SDK’s documentation of how to retrieve a single item:

TableResult retrievedResult = table.Execute(retrieveOperation);

// Print the phone number of the result.
if (retrievedResult.Result != null)
   Console.WriteLine(((CustomerEntity)retrievedResult.Result).PhoneNumber);
else
   Console.WriteLine("The phone number could not be retrieved.");

Based on the example, the retrievedResult.Result should be null, if no row was found. But actually this isn’t the case, as the table.Execute throws an exception if no row is found.

This was true with the old SDK also: An exception was thrown if no row was found. But there was a property which turned this off:

TableServiceContext.IgnoreResourceNotFoundException = true

But where is this option hidden in the new SDK?

Answer 1

It seems to be in the same place in my SDK 1.8 as it has always been, but it has moved in the 2.0 version of the storage API. Is that what you’re using?

Microsoft.WindowsAzure.StorageClient.TableServiceContext has moved to Microsoft.WindowsAzure.Storage.Table.DataServices.TableServiceContext.

The property you’re looking for seems to still be available there 🙂
