Outlook 联系人 API - 分页结果

Question

我正在尝试显示所选帐户的所有 Outlook 联系人。当一个帐户有几千个联系人时，下面的代码只显示前 n 个联系人。 contactResults 对象有一个 MorePagesAvailable 属性和一个可用的 GetNextPageAsync() 方法，但我显然不知道如何使用它们。有人可以请教我。

string token = (string)Session["access_token"];
string email = (string)Session["user_email"];

// Since we have the token locally from the Session, just return it here
OutlookServicesClient client = new OutlookServicesClient(new Uri("https://outlook.office.com/api/v2.0"), async () => { return token; });

client.Context.SendingRequest2 += new EventHandler<SendingRequest2EventArgs>((sender, e) => InsertXAnchorMailboxHeader(sender, e, email));

var contactResults = await client.Me.Contacts
                    .OrderBy(c => c.DisplayName)
                    .Take(2500)
                    .Select(c => new DisplayContact(c))
                    .ExecuteAsync();

foreach (DisplayContact displayContact in contactResults.CurrentPage)
    System.Diagnostics.Debug.WriteLine(displayContact);

var contactResults = await client.Me.Contacts
                .OrderBy(c => c.DisplayName)
                .Select(c => new DisplayContact(c))
                .ExecuteAsync();

while (true)
{
    foreach (DisplayContact displayContact in contactResults.CurrentPage)
        System.Diagnostics.Debug.WriteLine(displayContact);

    if (contactResults.MorePagesAvailable)
        contactResults = await contactResults.GetNextPageAsync();
    else
        break;
}
