WP8.1RT中，如何修改人脉中的联系人，

Question

我搜了很多信息都没找到，我是想通过程序修改人脉中联系人的头像，不知sdk中是否提供相关接口？

Answer 1

你好，

我们可以使用StoredContact.SetDisplayPictureAsync方法去设置联系人头像，以下是我的代码示例：

private async void Button_Click(object sender, RoutedEventArgs e)
{
            ContactStore contactStore = await ContactStore.CreateOrOpenAsync(ContactStoreSystemAccessMode.ReadWrite, ContactStoreApplicationAccessMode.ReadOnly);

            ContactInformation contactInformation = new ContactInformation();
            var properties = await contactInformation.GetPropertiesAsync();
            properties.Add(KnownContactProperties.FamilyName, "test");
            properties.Add(KnownContactProperties.Telephone, "12345678");
            StoredContact storeContact = new StoredContact(contactStore, contactInformation);

            StorageFile imagefile = await StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///Assets/Build.png", UriKind.RelativeOrAbsolute));
            Stream stream = await imagefile.OpenStreamForReadAsync();
            IInputStream inputStream = stream.AsInputStream();
            await storeContact.SetDisplayPictureAsync(inputStream);
            await storeContact.SaveAsync();

            //Get Current Contact Avatar
            IRandomAccessStream raStream = await storeContact.GetDisplayPictureAsync();

            BitmapImage bi = new BitmapImage();
            bi.SetSource(raStream);
            img.Source = bi;
}

多谢您的回答，

我在网上也找到诸如您提供的代码，奇怪的是，我这里的ContactStore并没有CreateOrOpenAsync方法：

我用的是WP8.1RT框架，
