c# – Deployment.Current.Dispatcher.BeginInvoke如何在Windows应用商店中运行?
作者:互联网
我有使用Windows Phone 8的经验,我正在使用WCF数据服务,我能够使用以下代码成功更新我的记录:
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");
}
}
);
}
但我在窗口商店应用程序中编写相同的代码时出现问题,我无法更新记录,我在这里遇到问题:Deployment.Current.Dispatcher.BeginInvoke
任何人都可以指导我,或重写我的代码?
谢谢
解决方法:
您是否尝试过使用此而不是Deployment.Current.Dispatcher.BeginInvoke
CoreDispatcher dispatcher = CoreWindow.GetForCurrentThread().Dispatcher;
await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
{
});
编辑:
然后整个方法是:
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");
}
});
}
