c# - 您的营销事件尚未准备好使用 C# 在 mailchimp api v3 中发送

Question

我创建了代码，通过使用 C# 控制台使用 mailchimp api v3.0 来立即发送事件。当我尝试免费帐户时一切顺利，但是当我升级我的高级帐户时我遇到了这个问题(只添加 2 个成员)。

我的场景:

1. 创造受众 => 成功
2. 将成员订阅者添加到我创建的受众中 => 成功
3. 使用特定模板创建事件 => 成功
4. 在已创建的事件中发送 cehcklist => 返回 is_ready false
5. 发送事件 => 返回您的事件尚未准备好发送

当我尝试使用控制台 c# consume mailchimp api 运行我的控制台程序时，出现此错误:

Type: http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/
Title: Bad Request
Status: 400
Detail: Your Campaign is not ready to send.
instance: 214b85f4-a288-44e7-b890-35925d8601ac

当我将事件检查到 mailchimp 网站门户时，我看到了这样一条消息:

To send, you need at least 1 subscriber in your list.

这意味着我的事件中没有收件人，这里是详细截图:

请问有没有人也遇到过这种情况？我非常感谢任何建议。

在发送事件之前有什么办法可以解决这个问题吗？因为当我检查 mailchimp 门户(基于上面显示的屏幕截图)时，我回到事件列表然后打开我的事件上面的问题自动解决，这是我的困惑。

因为 mailchimp api v3.0 限制一次调用只能有 500 名订阅者，最后我创建了一个类来划分我的列表:

//partition list of members more than 500 
public static class Extensions
{
    public static List<List<T>> SplitPartition<T>(this IEnumerable<T> collection, int size)
    {
        var chunks = new List<List<T>>();
        var count = 0;
        var temp = new List<T>();

        foreach (var element in collection)
        {
            if (count++ == size)
            {
                chunks.Add(temp);
                temp = new List<T>();
                count = 1;
            }
            temp.Add(element);
        }
        chunks.Add(temp);

        return chunks;
    }
}

这是我的主要代码，使用多种场景来处理单个方法，可以通过多种方式调用:

    static MailChimpProcessor()

        ApiHelper.InitializeClient(baseUrl, apiKey);

试试下面的代码

                //create campaign using post method
                var campaignResult = CampaignProcessor.PostCampaignAsync(campaignModel).Result;

                    bool isReadySend = false;
