'SubscriptionClient' 不包含 'PeekBatch' 和 ReceiveBatch 的定义

Question

我有一个 netstandard2.1 应用程序，我正在使用 nuget 包 "Microsoft.Azure.ServiceBus" Version="4.1.1"。

我正在创建一个 azure 服务总线 SubscriptionClient 并尝试使用 PeekBatch 和 ReceiveBatch，但我遇到了以下错误，这里缺少什么？

'SubscriptionClient' does not contain a definition for 'PeekBatch' and no accessible extension method 'PeekBatch' accepting a first argument of type 'SubscriptionClient' could be found

'SubscriptionClient' does not contain a definition for 'ReceiveBatch' and no accessible extension method 'PeekBatch' accepting a first argument of type 'SubscriptionClient' could be found

 _subscriptionClient = new SubscriptionClient(connectionString, topicName, subscriptionName, ReceiveMode.ReceiveAndDelete);
            
            _subscriptionClient.PrefetchCount = 16;

            while (_subscriptionClient.PeekBatch(16).Any())
            {
                var pendingMessages = _subscriptionClient.ReceiveBatch(16, TimeSpan.FromSeconds(1))?.ToList();
                if (pendingMessages != null)
                {
                    foreach (var message in pendingMessages)
                    {
                        // do processing of the message
                    }
                }
            }

您目前无法使用 .net standard 或 core 中的批处理方法和预取。

在此处查看文档：https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-performance-improvements?tabs=net-standard-sdk#prefetching-and-receivebatch

Prefetching

This section only applies to the WindowsAzure.ServiceBus SDK, as the Microsoft.Azure.ServiceBus SDK does not expose batch functions.

请注意此处的 WindowsAzure：https://www.nuget.org/packages/WindowsAzure.ServiceBus/

Please note that this package requires at least .Net Framework 4.6.2.

仅是 .net，不支持 net core 或 net standard
