So I am cruising through the ASP.NET C# MVP web project we are working on, and happened upon this method (again, the names were changed to protect the not so innocent):

private void mView_LoadObjects(object sender, EventArgs e)
{
    try
    {
        try
        {
            BusinessLayer.Class1 bizClass = new BusinessLayer.Class1();
            mView.objects = bizClass.GetObjects(mView.ID1, mView.ID2);
        }
        catch (Exception ex)
        {
            System.Diagnostics.Debug.WriteLine(ex.Message);
            throw;
        }
    }
    catch (Exception ex)
    {
        System.Diagnostics.Debug.WriteLine(ex.Message);
        throw;
    }
}

However, the fun didn’t stop there.  A little further down the class, I found this:

private void mView_LoadOtherObjects(object sender, EventArgs e)
{
    try
    {

    }
    catch (Exception ex)
    {
        System.Diagnostics.Debug.WriteLine(ex.Message);
        throw;
    }
}

I am thinking that the catch block on this second example was not hit very often.
