Question

我一直试图将此异常记录几天，但无法弄明白。所以我想我在这里发布，希望有人可以提供帮助。我还发布了一些我正在使用的代码来捕获未处理的异常，但异常从未出现在日志文件中。

如果有人可以帮助我，我将不胜感激。

要处理未处理的异常，请创建一个这样的方法

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

此外，当您执行任何方法时，只需将此方法包含在此LogFailedOperations方法中，就像这些示例一样 -

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 */ });
}
