Windows Phone中的多线程C＃？



当我调用wcf服务时如何进行多线程处理。一个线程应该调用服务，一个线程应该显示处理。

解决方案

嗨。我建议你使用Reactive Extensions for windows phone。

借助这个第三方库Rx（顺便由LINQ创始人之一编写），您可以在一个线程上调用服务并在另一个线程上观察结果。



例如，让我们从服务中获取json数据：

 WebClient webClient =  new  WebClient（）; 
 webClient.Headers.Add（  uid，LoginData.LoginName）; 
 webClient.Headers.Add（  pass，LoginData.Password）; 
 webClient.Headers.Add（  logonType，  0）; 
  var  eventStream = Observable.FromEventPattern< DownloadDataCompletedEventArgs>（webClient，  DownloadDataCompleted）。 
 SubscribeOn（Scheduler.NewThread）.Select（newData = >  newData.EventArgs.Result）; 
 
 eventStream.ObserveOn（System.Threading.SynchronizationContext.Current）.Subscribe（OnDatareceived，
  //  有错误 
 ex = >  
 {
 System.Windows.MessageBox.Show（ ex.Message）; 
 ViewModel.ViewModelLocator.Logger.Error（ string  .Empty，ex）; 
}）; 
 
 webClient.DownloadDataAsync（ new  Uri（ConfigurationManager.AppSettings [  loginUrl]））; 
 weakClient.Dispose（）; 
 weakClient =  null ; 
 
  void  OnDatareceived（ byte  [] data）
 {
  if （data！=  null ）{
  //  将字节数组转换为字符串并将其反序列化为对象 
} 
 
} 

Multi threading in windows phone C# ?

How to do multithreading when i call a wcf service . One thread should call service and one thread should show processing.

解决方案

Hi. I''m recommend to U to use Reactive Extensions for windows phone.
With help of this third-party library Rx(by the way it was wrriten by one of the LINQ founder ) you can achive such ability to call service on one thread and observe result on another.

For example let get json data from service:

WebClient webClient = new WebClient();
            webClient.Headers.Add("uid", LoginData.LoginName);
            webClient.Headers.Add("pass", LoginData.Password);
            webClient.Headers.Add("logonType", "0");
            var eventStream = Observable.FromEventPattern<DownloadDataCompletedEventArgs>(webClient, "DownloadDataCompleted").
                SubscribeOn(Scheduler.NewThread).Select(newData => newData.EventArgs.Result);

eventStream.ObserveOn(System.Threading.SynchronizationContext.Current).Subscribe(OnDatareceived,
                //on error
                ex =>
                {
                    System.Windows.MessageBox.Show(ex.Message);
                    ViewModel.ViewModelLocator.Logger.Error(string.Empty, ex);
                });

            webClient.DownloadDataAsync(new Uri(ConfigurationManager.AppSettings["loginUrl"]));
            weakClient.Dispose();
            weakClient = null;

void OnDatareceived(byte[] data)
		{
			if(data!=null){
//convert byte array to string and deserialize it to object
}

}
