BackgroundWorker example

Question

Could you please provide an example how to use background worker. I have created Background worker follow the instruction provided in documentation for asp.net boilerplate. Inherit my class from

public class ContactValidationBackgroundWorker : BackgroundWorkerBase, ITransientDependency

Override Start method and put into non-blocking Task.Run(MyMethod). Then I add wait instruction into Overrided method WaitToStop, add like myTask.Wait();

This method starts , but it block performing main process of work. I'm using Asp.net(boilerplate) core + Angular (SPA) I added it into Application Services layer.

Answer 1

public partial class MainWindow : Window
{
    //defining the backgroundworker
    private BackgroundWorker bgworker = new BackgroundWorker();

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

    private void initializeBackgroundWorker()
    {
        bgworker.DoWork += MyBackgroundWorker_DoWork;
    }

    private void MyBackgroundWorker_DoWork(object sender, DoWorkEventArgs e)
    {
        //method you want to execute in the backgroundWorker
        MyMethod();
    }

    private void Mouse_Enter(object sender, MouseEventArgs e)
    {
        //call the backgroundWorker and execute it
        //This will execute the method simultaneouly with other methods 
        //without blocking the UI 

        bgworker.RunWorkerAsync();
    }

    private void MyMethod()
    {
        //your method's code
    }

}

The above code shows how to define, initialize and execute a backgroundWorker in a WPF or winform application using C#. Refer to the inline comments in the code to understand what each part of code does.
