C＃自动检查功能

Question

I have a function called Checking() to update my UI. I'd like to make this function AutoRun and every 1 Second it runs it and updates my UI.

How can I do that?

Here is my function:

public MainWindow()
{
    InitializeComponent();
    Checking()
}

public void Checking()
{
    if (status= Good)
        UI.color.fill= Green
    else
        UI.color.Fill = Red
}

This code can help you

//need to add  System.Timers in usings
using System.Timers;

//inside you code
//create timer with interval 2 sec
Timer timer=new Timer(2000);
//add eventhandler 
timer.Elapsed+=new ElapsedEventHandler(timer_Elapsed);
//start timer
timer.Start();


private void timer_Elapsed(object sender, ElapsedEventArgs e)
    {
        MessageBox.Show("324");
        //or other actions
    }

Answer 2

You'll want to make sure the changes made in Checking() are bound and a IPropertyNotifyChange sent for it.

using System.Reactive;
public MainWindow()
{
    InitializeComponent();
    Observable.Interval(TimeSpan.FromSeconds(1))
        .Subscribe( _ => Checking() );
}

DispathTimer is timer, that working in one thread with UI. This code can help you

 public partial class MainWindow : Window {
    public MainWindow() {
        InitializeComponent();

        DispatcherTimer timer = new DispatcherTimer(){Interval = new TimeSpan(0,0,0,1)};
        timer.Tick += new EventHandler(timer_Tick);
        timer.Start();
    }

    void timer_Tick(object sender, EventArgs e) {
        Checking();
    }

    public void Checking()
    {   
       .....
    }
