你如何获得Azure的主题订阅消息计数？ [英] How do you get the message count for Azure Topic Subscription?

问题描述

有没有办法让一个Azure的主题订阅当前消息计数？

Is there a way to get the current message count for an Azure topic subscription?

我看到SubscriptionDescription类有一个MessageCount属性，但这类似乎只能用于创建订阅。我没有看到一个方法来检索现有订阅的SubscriptionDescription对象。

I see that the SubscriptionDescription class has a MessageCount property, but this class appears to only be used to create a subscription. I don't see a way to retrieve a SubscriptionDescription object for an existing subscription.

推荐答案

我发现我一直在寻找的：

I found what I was looking for:

var namespaceManager = NamespaceManager.CreateFromConnectionString(connectionString);
var subscriptionDesc = namespaceManager.GetSubscription(topicPath, subscriptionName);
long messageCount = subscriptionDesc.MessageCount;
