How can I avoid duplicated try catch blocks

Question

I have several methods that look like this:

public void foo()
{
   try 
   {
      doSomething();
   }
   catch(Exception e)
   {
      Log.Error(e);
   }
 }

If you don't want to use an AOP approach, a method used at one of my previous employers for common exception handling across a set of class was to have a base class with a method similar to the following

    protected TResult DoWrapped(Func action)
    {
        try
        {
            return action();
        }
        catch (Exception)
        {
            // Do something
            throw;
        }
    }

With methods looking like.

    public object AMethod(object param)
    {
        return DoWrapped(() =>
                      {
                          // Do stuff
                          object result = param;
                          return result;
                      });
    }

Can't remember exactly, it's been a while. But similar to this.
