Example

The following example shows how to use this message. For this sample to work correctly, you must be connected to the server to get an IOrganizationService interface. For the complete sample, see the link later in this topic.

// Get the list of audit partitions.
RetrieveAuditPartitionListResponse partitionRequest =
    (RetrieveAuditPartitionListResponse)_service.Execute(new RetrieveAuditPartitionListRequest());
AuditPartitionDetailCollection partitions = partitionRequest.AuditPartitionDetailCollection;

// Create a delete request with an end date earlier than possible.
DeleteAuditDataRequest deleteRequest = new DeleteAuditDataRequest();
deleteRequest.EndDate = new DateTime(2000, 1, 1);

// Check if partitions are not supported as is the case with SQL Server Standard edition.
if (partitions.IsLogicalCollection)
{
    // Delete all audit records created up until now.
    deleteRequest.EndDate = DateTime.Now;
}

// Otherwise, delete all partitions that are older than the current partition.
// Hint: The partitions in the collection are returned in sorted order where the 
// partition with the oldest end date is at index 0.
else
{
    for (int n = partitions.Count - 1; n >= 0; --n)
    {
        if (partitions[n].EndDate <= DateTime.Now && partitions[n].EndDate > deleteRequest.EndDate)
        {
            deleteRequest.EndDate = (DateTime)partitions[n].EndDate;
            break;
        }
    }
}

// Delete the audit records.
if (deleteRequest.EndDate != new DateTime(2000, 1, 1))
{
    _service.Execute(deleteRequest);
    Console.WriteLine("Audit records have been deleted.");
}
else
    Console.WriteLine("There were no audit records that could be deleted.");

' Get the list of audit partitions.
Dim partitionRequest As RetrieveAuditPartitionListResponse = CType(_service.Execute(New RetrieveAuditPartitionListRequest()), RetrieveAuditPartitionListResponse)
Dim partitions As AuditPartitionDetailCollection = partitionRequest.AuditPartitionDetailCollection

' Create a delete request with an end date earlier than possible.
Dim deleteRequest As New DeleteAuditDataRequest()
deleteRequest.EndDate = New Date(2000, 1, 1)

' Check if partitions are not supported as is the case with SQL Server Standard edition.
If partitions.IsLogicalCollection Then
    ' Delete all audit records created up until now.
    deleteRequest.EndDate = Date.Now

    ' Otherwise, delete all partitions that are older than the current partition.
    ' Hint: The partitions in the collection are returned in sorted order where the 
    ' partition with the oldest end date is at index 0.
Else
    For n As Integer = partitions.Count - 1 To 0 Step -1
        If partitions(n).EndDate <= Date.Now AndAlso partitions(n).EndDate > deleteRequest.EndDate Then
            deleteRequest.EndDate = CDate(partitions(n).EndDate)
            Exit For
        End If
    Next n
End If

' Delete the audit records.
If deleteRequest.EndDate <> New Date(2000, 1, 1) Then
    _service.Execute(deleteRequest)
    Console.WriteLine("Audit records have been deleted.")
Else
    Console.WriteLine("There were no audit records that could be deleted.")
End If
