本文介绍了如何在Windows商店应用的Deployment.Current.Dispatcher.BeginInvoke工作?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我得到的Windows Phone 8的经验和我使用WCF数据服务,我能够用下面的代码成功更新我的记录:
i got experience with windows phone 8 and i am using WCF data services, i am able to update my record successfully with following code :
public void UpdateJob1(EquipBooking equipBooking)
{
this._context.UpdateObject(equipBooking);
this._context.BeginSaveChanges(OnChangesSaved, this._context);
}
private void OnChangesSaved(IAsyncResult result)
{
bool errorFound = false;
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
this._context = result.AsyncState as THA001_devEntities;
try
{
// Complete the save changes operation.
this._context.EndSaveChanges(result);
}
catch (DataServiceRequestException ex)
{
errorFound = true;
MessageBox.Show("Error, While Updating Record");
}
if (!errorFound)
{
MessageBox.Show("Record Successfully Updated");
}
}
);
}
但我得到的问题,同时在窗口商店应用写相同的代码,我不能够更新记录,我有问题就在这里: Deployment.Current.Dispatcher.BeginInvoke
能任何人引导我,或重写我的代码?
can anyone guide me, or rewrite my code?
感谢
推荐答案
您是否尝试过使用,而不是Deployment.Current.Dispatcher.BeginInvoke这个
Have you tried using this instead of the Deployment.Current.Dispatcher.BeginInvoke
CoreDispatcher dispatcher = CoreWindow.GetForCurrentThread().Dispatcher;
await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
{
});
编辑:
那么整个方法是:
private async void OnChangesSaved(IAsyncResult result)
{
bool errorFound = false;
CoreDispatcher dispatcher = CoreWindow.GetForCurrentThread().Dispatcher;
await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
{
this._context = result.AsyncState as THA001_devEntities;
try
{
// Complete the save changes operation.
this._context.EndSaveChanges(result);
}
catch (DataServiceRequestException ex)
{
errorFound = true;
MessageBox.Show("Error, While Updating Record");
}
if (!errorFound)
{
MessageBox.Show("Record Successfully Updated");
}
});
}
