使用Azure.Messaging.ServiceBus。
我想在一个事务中向Azure服务总线发送多条消息。我很好每个事务100条消息的限制。
这两种方法的优缺点是什么？

事务作用域

• TransactionScope中的多个单消息发送操作。*

public async Task SendMessages(IEnumerable<ServiceBusMessage> messages, CancellationToken cancellationToken)
{
    using var transaction = new TransactionScope(TransactionScopeAsyncFlowOption.Enabled);

    var tasks = messages.Select(m => _serviceBusSender.SendMessageAsync(m, cancellationToken));
    await Task.WhenAll(tasks);

    transaction.Complete();
}

ServiceBusMessageBatch

• 单次发送操作，发送ServiceBusMessageBatch。*

public async Task SendMessages(IEnumerable<ServiceBusMessage> messages, CancellationToken cancellationToken)
{
    var batch = await _serviceBusSender.CreateMessageBatchAsync(cancellationToken);

    foreach (var message in messages)
    {
        if (!batch.TryAddMessage(message))
            throw new Exception("...");
    }

    await _serviceBusSender.SendMessagesAsync(batch, cancellationToken);
}
