Throwing the same exception as passed to the 'catch' block lose the original stack trace and will make debugging this exception a lot more difficult.
The correct way to rethrow an exception without changing it is by using 'throw' without any parameter.

{% highlight csharp %} try { } catch (System.Exception ex) { throw ex; } {% endhighlight %}

You will have two choices: you can rethrow the original exception as is:

{% highlight csharp %} try { } catch (System.Exception ex) { throw; } {% endhighlight %}

Or you can rethrow the original exception as an inner exception, like so:

{% highlight csharp %} try { } catch (System.Exception ex) { throw new Exception("some reason to rethrow", ex); } {% endhighlight %}
