DeleteMessageBatchRequest Class | AWS SDK for .NET V2

Container for the parameters to the DeleteMessageBatch operation. Deletes up to ten messages from the specified queue. This is a batch version of DeleteMessage. The result of the delete action on each message is reported individually in the response.

Because the batch request can result in a combination of successful and unsuccessful actions, you should check for batch errors even when the call returns an HTTP status code of 200.

Some API actions take lists of parameters. These lists are specified using the

param.n

notation. Values of

are integers starting from 1. For example, a parameter list with two elements looks like this:

&Attribute.1=this

&Attribute.2=that

Batch delete messages example

var client = new AmazonSQSClient();

var request = new ReceiveMessageRequest
{
  AttributeNames = new List<string>() { "All" },
  MaxNumberOfMessages = 5,
  QueueUrl = "https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyTestQueue",
  VisibilityTimeout = (int)TimeSpan.FromMinutes(10).TotalSeconds,
  WaitTimeSeconds = (int)TimeSpan.FromSeconds(5).TotalSeconds
};

var response = client.ReceiveMessage(request);
var batchEntries = new List<DeleteMessageBatchRequestEntry>();

if (response.Messages.Count > 0)
{
  foreach (var message in response.Messages)
  {
    var batchEntry = new DeleteMessageBatchRequestEntry
    {
      Id = message.MessageId,
      ReceiptHandle = message.ReceiptHandle
    };

    batchEntries.Add(batchEntry);
  }

  var delRequest = new DeleteMessageBatchRequest
  {
    Entries = batchEntries,
    QueueUrl = "https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyTestQueue"
  };

  var delResponse = client.DeleteMessageBatch(delRequest);

  if (delResponse.Failed.Count > 0)
  {
    Console.WriteLine("Failed deletions:");

    foreach (var failure in delResponse.Failed)
    {
      Console.WriteLine("  For ID '" + failure.Id + "': ");
      Console.WriteLine("    Code = " + failure.Code);
      Console.WriteLine("    Message = " + failure.Message);
      Console.WriteLine("    Sender's fault? = " + failure.SenderFault);
    }
  }

  if (delResponse.Successful.Count > 0)
  {
    Console.WriteLine("Successful deletions:");

    foreach (var success in delResponse.Successful)
    {
      Console.WriteLine("  ID '" + success.Id + "'");
    }
  }
}
