AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Changes the visibility timeout of multiple messages. This is a batch version of ChangeMessageVisibility. The result of the action on each message is reported individually in the response. You can send up to 10 ChangeMessageVisibility requests with each ChangeMessageVisibilityBatch action.

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 actions take lists of parameters. These lists are specified using the param.n notation. Values of n are integers starting from 1. For example, a parameter list with two elements looks like this:

&Attribute.1=this

&Attribute.2=that

Note:

For PCL and Unity this operation is only available in asynchronous form. Please refer to ChangeMessageVisibilityBatchAsync.

Batch change message visibility example

var client = new AmazonSQSClient();

var url = "https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyTestQueue";

// Receive messages.
var msgRequest = new ReceiveMessageRequest
{
  AttributeNames = new List() { "All" },
  QueueUrl = url
};

var msgResponse = client.ReceiveMessage(msgRequest);

// Change visibility timeout for each message.
if (msgResponse.Messages.Count > 0)
{
  var entries = new List();

  int numMessages = 0;

  foreach (var message in msgResponse.Messages)
  {
    numMessages += 1;

    var entry = new ChangeMessageVisibilityBatchRequestEntry
    {
      Id = "Entry" + numMessages.ToString(),
      ReceiptHandle = message.ReceiptHandle,
      VisibilityTimeout = (int)TimeSpan.FromMinutes(10).TotalSeconds
    };

    entries.Add(entry);
  }

  var batRequest = new ChangeMessageVisibilityBatchRequest
  {
    Entries = entries,
    QueueUrl = url
  };

  var batResponse = client.ChangeMessageVisibilityBatch(batRequest);

  Console.WriteLine("Successes: " + batResponse.Successful.Count +
    ", Failures: " + batResponse.Failed.Count);

  if (batResponse.Successful.Count > 0)
  {
    foreach (var success in batResponse.Successful)
    {
      Console.WriteLine("  Success ID " + success.Id);
    }
  }

  if (batResponse.Failed.Count > 0)
  {
    foreach (var fail in batResponse.Failed)
    {
      Console.WriteLine("  Failure ID " + fail.Id + ":");
      Console.WriteLine("    Code: " + fail.Code);
      Console.WriteLine("    Message: " + fail.Message);
      Console.WriteLine("    Sender's fault?: " + fail.SenderFault);
    }
  }
}
