捕获由Assembly.CreateInstance()方法Reflection创建的表单上的异常

            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

请告诉我如何捕获表单上的按钮单击事件上发生的异常它是使用方法创建的 CreateFormInstance() .

我的按钮点击代码是：

  private void button1_Click(object sender, EventArgs e)
        {
            throw new NullReferenceException("nullref test muh sa");
        }

我想要创建此表单的父表单中的异常。
