在VS 2017中使用VB.NET，我可以使所有人通过下面的代码，但是我无法获取/读取用户定义的字段
Dim peopleRequest As PeopleResource.ConnectionsResource.ListRequest = service.People.Connections.List("people/me")
peopleRequest.RequestMaskIncludeField = "person.addresses,person.emailAddresses,person.organizations,person.names,person.memberships,person.metadata,person.occupations,person.PhoneNumbers,person.Taglines,person.userDefined"
Dim people As ListConnectionsResponse = peopleRequest.Execute()
