Async and await in C #

public class MyClass
{
Public MyClass ()
{
Displayvalue (); There's no blocking.
System.Diagnostics.Debug.WriteLine ("MyClass () End.");
}
Public task<double> Getvalueasync (double num1, double num2)
{
Return Task.run (() =
{
for (int i = 0; i < 1000000; i++)
{
NUM1 = num1/num2;
}
return NUM1;
});
}
Public async void Displayvalue ()
{
Double result = await Getvalueasync (1234.5, 1.01);//This will open a new thread to process the Getvalueasync task, then return the method immediately
All code after this is encapsulated as a delegate, which is called when the Getvalueasync task completes.
System.Diagnostics.Debug.WriteLine ("Value is:" + result);
}
}
