Constructors

QueueClientOptions(QueueClientOptions+ServiceVersion)

Initializes a new instance of the QueueClientOptions class.

Properties

Audience	Gets or sets the Audience to use for authentication with Azure Active Directory (AAD). The audience is not considered when using a shared key.
Diagnostics	Gets the client diagnostic options. (Inherited from ClientOptions)
EnableTenantDiscovery	Enables tenant discovery through the authorization challenge when the client is configured to use a TokenCredential. When enabled, the client will attempt an initial un-authorized request to prompt a challenge in order to discover the correct tenant for the resource.
GeoRedundantSecondaryUri	Gets or sets the secondary storage Uri that can be read from for the storage account if the account is enabled for RA-GRS. If this property is set, the secondary Uri will be used for GET or HEAD requests during retries. If the status of the response from the secondary Uri is a 404, then subsequent retries for the request will not use the secondary Uri again, as this indicates that the resource may not have propagated there yet. Otherwise, subsequent retries will alternate back and forth between primary and secondary Uri.
MessageEncoding	Gets or sets a message encoding that determines how Body is represented in HTTP requests and responses. The default is None.
Retry	Gets the client retry options. (Inherited from ClientOptions)
RetryPolicy	Gets or sets the policy to use for retries. If a policy is specified, it will be used in place of the Retry property. The RetryPolicy type can be derived from to modify the default behavior without needing to fully implement the retry logic. If Process(HttpMessage, ReadOnlyMemory<HttpPipelinePolicy>) is overridden or a custom HttpPipelinePolicy is specified, it is the implementer's responsibility to update the ProcessingContext values. (Inherited from ClientOptions)
Transport	The HttpPipelineTransport to be used for this client. Defaults to an instance of HttpClientTransport. (Inherited from ClientOptions)
Version	Gets the QueueClientOptions.ServiceVersion of the service API used when making requests. For more, see For more information, see Versioning for the Azure Storage services.

Methods

AddPolicy(HttpPipelinePolicy, HttpPipelinePosition)

Adds an HttpPipeline policy into the client pipeline. The position of policy in the pipeline is controlled by the position parameter. If you want the policy to execute once per client request use PerCall otherwise use PerRetry to run the policy for every retry. Note that the same instance of policy would be added to all pipelines of client constructed using this ClientOptions object.

(Inherited from ClientOptions)

Events

MessageDecodingFailed

Optional. Performs the tasks needed when a message is received or peaked from the queue but cannot be decoded.

Such message can be received or peaked when QueueClient is expecting certain QueueMessageEncoding but there's another producer that is not encoding messages in expected way. I.e. the queue contains messages with different encoding.

QueueMessageDecodingFailedEventArgs contains QueueClient that has received the message as well as ReceivedMessage or PeekedMessage with raw body, i.e. no decoding will be attempted so that body can be inspected as has been received from the queue.

The QueueClient won't attempt to remove the message from the queue. Therefore such handling should be included into the event handler itself.

The handler is potentially invoked by both synchronous and asynchronous receive and peek APIs. Therefore implementation of the handler should align with QueueClient APIs that are being used. See SyncAsyncEventHandler<T> about how to implement handler correctly. The example below shows a handler with all possible cases explored.

QueueClientOptions queueClientOptions = new QueueClientOptions()
{
    MessageEncoding = QueueMessageEncoding.Base64
};

queueClientOptions.MessageDecodingFailed += async (QueueMessageDecodingFailedEventArgs args) =>
{
    if (args.PeekedMessage != null)
    {
        Console.WriteLine($"Invalid message has been peeked, message id={args.PeekedMessage.MessageId} body={args.PeekedMessage.Body}");
    }
    else if (args.ReceivedMessage != null)
    {
        Console.WriteLine($"Invalid message has been received, message id={args.ReceivedMessage.MessageId} body={args.ReceivedMessage.Body}");

        if (args.IsRunningSynchronously)
        {
            args.Queue.DeleteMessage(args.ReceivedMessage.MessageId, args.ReceivedMessage.PopReceipt);
        }
        else
        {
            await args.Queue.DeleteMessageAsync(args.ReceivedMessage.MessageId, args.ReceivedMessage.PopReceipt);
        }
    }
};

QueueClient queueClient = new QueueClient(connectionString, queueName, queueClientOptions);
