记录未处理的异常

Question

I have been trying to log this exception for days but cant figure it out. So I thought I post it here with the hope that someone could help. I have also posted some of my code that I'm currently using to catch unhandled exceptions but the exception never showed up in the log file.

I would appreciate if someone could help me.

For handling unhandled exceptions, please create a method like this

   protected TResult LogFailedOperations<TResult>(Func<TResult> action)
        {
            try
            {
                return action();
            }
            catch (Exception ex)
            {
                // Logic for logging from ex.Message
            }
        }

Also, when you perform any method, just enclose that method around this LogFailedOperations method like these examples -

private void MyButton_Click(object sender, RoutedEventArgs e)
{
  var result = LogFailedOperations(() => { /* Your logic for button click */ });
}

private void LoadDataToView()
{
  var result = LogFailedOperations(() => { /* Your logic for laoding data */ });
}

private void Slider_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
{
  var result = LogFailedOperations(() => { /* Your logic for slider changed event */ });
}
