我有使用 Windows Phone 8 的经验并且我正在使用 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");
}
}
);
}
但是我在窗口应用程序中编写相同的代码时遇到了问题,我无法更新记录,我在这里遇到了问题:Deployment.Current.Dispatcher.BeginInvoke
谁能指导我,或者重写我的代码?
谢谢
最佳答案
你试过用这个代替 Deployment.Current.Dispatcher.BeginInvoke
CoreDispatcher dispatcher = CoreWindow.GetForCurrentThread().Dispatcher;
await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
{
});
编辑:
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");
}
});
}
