|---|---|---|
|
ChangeMessageVisibilityBatchRequestEntry() | Empty constructor used to set properties independently even when a simple constructor is available |
|
ChangeMessageVisibilityBatchRequestEntry(string, string) | Instantiates ChangeMessageVisibilityBatchRequestEntry with the parameterized properties |
| Name | Type | Description | |
|---|---|---|---|
|
Id | System.String |
Gets and sets the property Id.
An identifier for this particular receipt handle. This is used to communicate the
result. Note that the |
|

This example shows how to change message visibility in batch.

};
var msgResponse = client.ReceiveMessage(msgRequest);
// Change visibility timeout for each message.
if (msgResponse.Messages.Count > 0)
{
var entries = new List<ChangeMessageVisibilityBatchRequestEntry>();
