How to determine whether Task.Run is completed within a loop

Question

This may be an odd question and it is really for my educational purpose so I can apply it in future scenarios that may come up.

I am using C#.

You can wait for your task to complete by awaiting your task like this

await webTask;

that will asynchronously wait for 'webTask' to complete. Instead of the timer you can use await Task.Delay which will asynchronously wait for the delay to expire. I would also consider making the wcf call asynchronous so you don't have to call inside Task.Run. See this question for some tips.

I'd rewrite the code as follows:

public async Task UploadAsync()
{
    while(true)
    {
        await Task.Delay(1000); // this is essentially your timer

        // wait for the webTask to complete asynchrnously
        await webTask;

        //keep count of competed tasks

        webTask = Task.Run(() =>
                        {
                            try 
                            { 
                                // consider generating an asynchronous method for this if possible.
                                wcf.UploadMotionDynamicRaw(bytes);  //my web service
                            }
                            catch (Exception ex)
                            {
                                //deal with error
                            }
                        });     
    }
}
