How to implement Basic Async Await method

Here is the basic way to implement Async - await method on your own. Here is an example (Winform project - .NET Framework)
bool started = false; //This is a flag telling if we have to display current Date and time public Form1() { InitializeComponent(); } private void timer1_Tick(object sender, EventArgs e) { if ( started) this.Text = DateTime.Now.ToLongTimeString(); //Display it if started is true } private void Form1_Load(object sender, EventArgs e) { // Normal intialization, - start the timer. LblName.Text = ""; this.Text = "Awaiting click the button"; timer1.Start(); }
//The async method itself, calling the Task.Delay with await prefix private async Task<string> ReadTextAsync() { await Task.Delay(TimeSpan.FromMilliseconds(6000)); //Set the timer-flag to false when counting is done started = false; this.Text = "Awaiting click the button"; return "Time done...."; } //Remember to set button click as async private async void button1_Click(object sender, EventArgs e) { LblName.Text = ""; started = true; string text = await ReadTextAsync(); LblName.Text = text; }
