Question

我能够获得联系人和群组。我无法做的是查询特定组的联系人。我已经阅读了文档，并且指定组Atom Id没有意义，因为存在类型冲突。

const string name = "MyGroup";
var uri = ContactsQuery.CreateGroupsUri("default");
var gQuery = new GroupsQuery(uri);
var group = cr.Get<Group>(gQuery).Entries.AsQueryable()
    .SingleOrDefault(e => e.GroupEntry.Title.Text.Contains(name));

uri = ContactsQuery.CreateContactsUri("default");
var cQuery = new ContactsQuery(uri);
if (group != null)
{
   cQuery.Group = (string)group.AtomEntry.Id;   //  WHAT TO PUT HERE ?
}
Feed<Contact> feed = cr.Get<Contact>(cQuery);

无法指定类型AtomId ...

group.AtomEntry.Id // type = AtomId

...为......的字符串类型

cQuery.group // type = string

谢谢！

更改...

cQuery.Group = (string)group.AtomEntry.Id;

为...

cQuery.Group = (string)group.Id;

提示来自this post。我意识到构造的URI很长并且包括[contacts URI] +？group = [group base / id URI]。示例：https://www.google.com/m8/feeds/contacts/default/full?group=http://www.google.com/m8/feeds/groups/user.email%40domain.com/base/some_alphanumeric_id

使用Google Contacts API v3，如何获取特定群组的联系人？
