Windows Phone 7 SDK学习之Microsoft.Phone.Tasks中的各项Task
有许多人或许会问，Windows Phone 7不允许访问本机的功能，使我们自己的程序完成共同的任务，比如发短信、发送email,但是你或许不能直接访问，但是Windows Phone 7 提供了间接的访问方式，那就是 Launchers & Choosers。通过他们我们就可以访问Windows Phone 7系统手机中的各项本机功能，并且微软已经为我们使用这些功能封装好了，我们只需要一个简单的调用就完全实现了。下面我们预览一下效果。
接下来我们进入正题
1.PhoneCallTask ：打电话
private void btnPhoneCall_Click(object sender, RoutedEventArgs e)
{
PhoneCallTask task = new PhoneCallTask();
task.PhoneNumber = "12345678901";
task.DisplayName = "吴建强";
task.Show();
}
2.SmsComposeTask:发送短信
private void btnComposeSms_Click(object sender, RoutedEventArgs e)
{
SmsComposeTask task = new SmsComposeTask();
task.To = "12345678901";
task.Body = "你好！.";
task.Show();
}
3.EmailComposeTask：发送邮件
EmailComposeTask task = new EmailComposeTask();
task.To = "wjqlxt@163.com";
task.Cc = "875867090@qq.com";
task.Subject = "测试";
task.Body = "你好啊！";
task.Show();
4.WebBrowserTask：开启Web浏览器
private void btnLaunchWebBrowser_Click(object sender, RoutedEventArgs e)
{
WebBrowserTask task = new WebBrowserTask();
task.URL = "http://www.cnblogs.com/salam";
task.Show();
}
5.SearchTask：搜索功能
private void btnLaunchSearch_Click(object sender, RoutedEventArgs e)
{
SearchTask task = new SearchTask();
task.SearchQuery = "吴建强";
task.Show();
}
6.MediaPlayerLauncher：启动媒体播放器
MediaPlayerLauncher task = new MediaPlayerLauncher();
task.Media = new Uri(@"http://ecn.channel9.msdn.com/o9/learn/videos/Silverlight4-SL4BusinessModule1-SL4LOB_01_01_Introduction/Silverlight4-SL4BusinessModule1-SL4LOB_01_01_Introduction_kit.wmv");
task.Show();
7.CameraCaptureTask：照相功能
private void btnTakePhoto_Click(object sender, RoutedEventArgs e)
{
CameraCaptureTask task = new CameraCaptureTask();
task.Completed += (s, evt) =>
{
if (evt.Error == null && evt.TaskResult == TaskResult.OK)
{
BitmapImage bmpImage = new BitmapImage();
bmpImage.SetSource(evt.ChosenPhoto);
image.Source = bmpImage;
}
};
task.Show();
}
8.PhotoChooserTask：选择照片功能
{
PhotoChooserTask task = new PhotoChooserTask();
task.Completed += (s, evt) =>
{
if (evt.Error == null && evt.TaskResult == TaskResult.OK)
{
BitmapImage bmpImage = new BitmapImage();
bmpImage.SetSource(evt.ChosenPhoto);
image.Source = bmpImage;
}
};
task.Show();
}
9.PhoneNumberChooserTask：选择联系人
private void btnSelectPhoneNumber_Click(object sender, RoutedEventArgs e)
{
PhoneNumberChooserTask task = new PhoneNumberChooserTask();
task.Completed += (s, evt) =>
{
if (evt.Error == null && evt.TaskResult == TaskResult.OK)
{
MessageBox.Show(evt.PhoneNumber + "请选择电话号码");
}
};
task.Show();
}
10.EmailAddressChooserTask：选择邮箱
private void btnSelectEmailAddress_Click(object sender, RoutedEventArgs e)
{
EmailAddressChooserTask task = new EmailAddressChooserTask();
task.Completed += (s, evt) =>
{
if (evt.Error == null && evt.TaskResult == TaskResult.OK)
{
MessageBox.Show(evt.Email + " 请选择邮件地址");
}
};
task.Show();
}
11.SavePhoneNumberTask：保存电话号码
private void btnSavePhoneNumber_Click(object sender, RoutedEventArgs e)
{
SavePhoneNumberTask task = new SavePhoneNumberTask();
task.PhoneNumber = "12345678901";
task.Show();
}
12.SaveEmailAddressTask：保存邮箱
private void btnSaveEmailAddress_Click(object sender, RoutedEventArgs e)
{
SaveEmailAddressTask task = new SaveEmailAddressTask();
task.Email = "875867090@qq.com";
task.Show();
}
13.PhoneNumberChooserTask和SmsComposeTask的结合使用
private void btnSms_Click(object sender, RoutedEventArgs e)
{
PhoneNumberChooserTask contactsTask = new PhoneNumberChooserTask();
contactsTask.Completed += (s, evt) =>
{
if (evt.Error == null && evt.TaskResult == TaskResult.OK)
{
SmsComposeTask smsTask = new SmsComposeTask();
smsTask.Body = "编辑内容.";
smsTask.To = evt.PhoneNumber;
smsTask.Show();
}
};
contactsTask.Show();
}
14.EmailAddressChooserTask和EmailComposeTask的结合使用
private void btnEmail_Click(object sender, RoutedEventArgs e)
{
EmailAddressChooserTask contactsTask = new EmailAddressChooserTask();
contactsTask.Completed += (s, evt) =>
{
if (evt.Error == null && evt.TaskResult == TaskResult.OK)
{
EmailComposeTask emailTask = new EmailComposeTask();
emailTask.Body = "编辑内容";
emailTask.To = evt.Email;
emailTask.Show();
}
};
contactsTask.Show();
}
