感谢

我尝试过的事情：

Hi,

I need to update UI via new thread during another background thread is running.

i.e

I need to update image of current button before it reaches to next page on button click.

thanks
Sunny

What I have tried:

public void GoNext()
        {



            if (touchDevice != null)
                CaptureTouch(touchDevice);


            //Create instance of current window data context
            var vm = DataContext as DeviceInfoViewModel;
            //if not null proceed
            if (vm != null)
            {
                // Gets the selected network adapter
                vm.AdapterDesc = Adapters.SelectedItem.ToString();

                //check if "None" is selected or not from the dropdown.
                //If not proceed with IP configuration
                if (!vm.AdapterDesc.Trim().ToLower().Equals(Settings.Default.NONE.ToLower()))
                {
                    //sets IP config to selected adapter.
                    vm.SetIpCommand.Execute(null);
                }
                //navigate to next window on successfull completion
                Navigate();
            }


        }

推荐答案

await Task.Run(() =>
            {
                int progress = 0;
                for (int i = 1; i < 5; i++)
                {
                    System.Threading.Thread.Sleep(1);
                    progress++;

                }
            });

只需将代码放在我们想要执行其他任务的代码之间。

Just put above code between the code where we want to do preform another task.
