您的广告系列尚未准备好使用 C# 在 mailchimp api v3 中发送

Question

我通过使用 C# 控制台使用 mailchimp api v3.0 创建了立即发送活动的代码。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（仅添加 2 个成员）。

我的场景：

1. 创建受众 => 成功
2. 将会员订阅者添加到我创建的受众群体中 => 成功
3. 使用特定模板创建广告系列 => 成功
4. 在已创建的活动中发送 cehcklist => return is_ready false
5. 发送广告系列 => 返回您的广告系列尚未准备好发送

当我尝试使用控制台 c# 使用 mailchimp api 运行我的控制台程序时，我收到了这个错误：

输入：http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/
标题：错误请求
状态：400
详细信息：您的广告系列尚未准备好发送。
实例：214b85f4-a288-44e7-b890-35925d8601ac

当我在 mailchimp 网站门户中查看活动时，我看到了这样的消息：

要发送，您的列表中至少需要 1 个订阅者。

这意味着我的活动中没有收件人，这里是详细截图：

请问有人也遇到过这种情况吗？我非常感谢任何建议。

在发送活动之前有什么办法可以解决这个问题吗？因为当我检查 mailchimp 门户时（基于上面显示的屏幕截图），我回到活动列表然后打开我的活动上面的问题自动解决，这是我的困惑。

因为 mailchimp api v3.0 一次通话限制为 500 名会员订阅者，最后我创建了类来划分我的列表：

//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几个场景来处理单个方法可以通过多种方式调用：

试试下面的代码

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