我正在使用this wrapper将MailChimp（API v3）集成到ASP.NET页面中，但是当它运行时，什么都没有发生！这是我的代码：

public partial class _Default : system.web.UI.Page
{
    IMailChimpManager manager = new MailChimpManager("my-KEY");
    IMailChimpManager mailChimpManager = new MailChimpManager("my-KEY");


    protected async System.Threading.Tasks.Task Page_LoadAsync(object sender,EventArgs e)
    {
        var listId = "my-ListID";
        // Use the Status property if updating an existing member
        var member = new Member 
        { 
            Emailaddress = $"githubTestaccount@test.com",StatusIfNew = Status.Subscribed 
        };
        member.MergeFields.Add("FNAME","HOLY");
        member.MergeFields.Add("LNAME","COW");
        await this.mailChimpManager.Members.AddOrupdateAsync(listId,member);
    }
}

开始调试时，我看到呼叫没有开始，我在做什么？我不明白！
