[UWP]UWP中获取联系人/邮件发送/SMS消息发送操作

这篇博客将介绍如何在UWP程序中获取联系人/邮件发送/SMS发送的基础操作。

1. 获取联系人

UWP中联系人获取需要引入Windows.ApplicationModel.Contacts名称空间。

ContactStore contactStore =
        await ContactManager.RequestStoreAsync(ContactStoreAccessType.AllContactsReadOnly);

IReadOnlyList<Contact> contacts = await contactStore.FindContactsAsync();

NOTE:

1). 获取的联系人列表是当前OS关联的微软账户(Hotmail/Outlook/Live邮箱)的联系人。

2). 获取联系人需要在Package.appxmanifest中将Contacts勾选上。

另外UWP提供了ContactPicker控件用来选取一个或者多个联系人，

ContactPicker contactPicker = new ContactPicker();

contactPicker.SelectionMode = ContactSelectionMode.Fields;

contactPicker.DesiredFieldsWithContactFieldType.Add(ContactFieldType.Email);
contactPicker.DesiredFieldsWithContactFieldType.Add(ContactFieldType.Address);
contactPicker.DesiredFieldsWithContactFieldType.Add(ContactFieldType.PhoneNumber);

//Select one or more contacts
IList<Contact> contacts = await contactPicker.PickContactsAsync();

if (contacts != null &&
    contacts.Count > 0)
{
    foreach (Contact contact in contacts)
    {
        // TODO:
    }
}

//// Select only one contact
//Contact contact = await contactPicker.PickContactAsync();

//if (contact != null)
//{
//      //TODO:...
//}

使用ContactPicker获取联系人时，不需要在Package.appxmanifest中勾选Contacts。

2. 邮件发送

private async void SendMail(Contact recipient, StorageFile attchmentFile)
{
    // Windows.ApplicationModel.Email
    EmailMessage message = new EmailMessage();
    // Mail subject
    message.Subject = "This is a test mail.";

    message.Body = "This is a test mail, please ignore.";

    if(attchmentFile != null)
    {
        RandomAccessStreamReference stream = 
            RandomAccessStreamReference.CreateFromFile(attchmentFile);

        EmailAttachment attachment = new EmailAttachment(attchmentFile.Name, stream);

        // Set mail's attachment
        message.Attachments.Add(attachment);
    }

    ContactEmail email = recipient.Emails.FirstOrDefault();

    if(email != null)
    {
        EmailRecipient emailRecipient = new EmailRecipient(email.Address);

        message.To.Add(emailRecipient);
    }

    await EmailManager.ShowComposeNewEmailAsync(message);
}

3. SMS消息发送

private async void ComposeSms(Contact recipient,
        string messageBody,
        StorageFile attachmentFile,
        string mimeType)
{
    var chatMessage = new Windows.ApplicationModel.Chat.ChatMessage();

    chatMessage.Body = messageBody;

    if (attachmentFile != null)
    {
        var stream = RandomAccessStreamReference.CreateFromFile(attachmentFile);

        var attachment = new Windows.ApplicationModel.Chat.ChatMessageAttachment(
            mimeType,
            stream);

        chatMessage.Attachments.Add(attachment);
    }

    var phone = recipient.Phones.FirstOrDefault<Windows.ApplicationModel.Contacts.ContactPhone>();
    if (phone != null)
    {
        chatMessage.Recipients.Add(phone.Number);
    }
    await Windows.ApplicationModel.Chat.ChatMessageManager.ShowComposeSmsMessageAsync(chatMessage);
}
