如何在winRT中使用contactPicker中的联系对象添加字段（使用C＃）？

问题描述

我使用 联系人Picker和ContactPickerUI创建了一个应用程序。我添加了这样的联系人字段：

I have created one application using contact Picker and ContactPickerUI. i have added the contact fields like this:

private void AddSampleContact(ContactModel addedContact)
{            
        Contact newContact = new Contact();
        IList<IContactField> contactfields = newContact.Fields;

        newContact.Name = addedContact.Name;
        string email = addedContact.Email;
        string phonono = addedContact.PhoneNo;
        ContactLocationField location = new ContactLocationField(addedContact.Location, ContactFieldCategory.Home);
                
        contactfields.Add(new ContactField(email, ContactFieldType.Email, ContactFieldCategory.None));
        contactfields.Add(new ContactField(phonono, ContactFieldType.PhoneNumber, ContactFieldCategory.Work));
        contactfields.Add(location);
        AddContactResult addResult = contactPickerUI.AddContact(addedContact.Id, newContact);
}

这里正在运作  perfect.i dun知道怎么样？看来contactfields是指向我的  newContact.Fields.is它如果不是那么它如何将字段分配给我的newContact对象，因为我将字段添加到contactfields而不是newContact.Fields。

推荐答案

IList<IContactField> contactfields = newContact.Fields;

contactfields和newContact.Fiedls是相同的列表，引用是相同的。

the contactfields and newContact.Fiedls are the same list, the reference is the same.

如果您更改了联系人字段，则更改newContact.Fiedls。

If you change the contactfields you are change the newContact.Fiedls.

但如果不想要，您可以尝试这样做：

but if don´t want you can try this:

IList<IContactField> contactfields = newContact.Fields.ToList();

使用System.Linq。

using System.Linq.

因为你想要一个包含这些项目的新列表，对吗？尽量清楚......

Because you want a new list with that items, right? Try to be clear...
