简单的反射

想起来研究下简单的反射，然后就在网上找了点资料，也找了点代码，大致如下：

 public static void PrintProperties<T>(T t)
        {
            if (t == null)
            {
                return;
            }

            PropertyInfo[] properties = t.GetType().GetProperties(BindingFlags.Instance | BindingFlags.Public);
            if (properties.Length <= 0)
            {
                return;
            }

            foreach (PropertyInfo item in properties)
            {
                string name = item.Name;
                object value = item.GetValue(t, null);
                if (item.PropertyType.IsValueType || item.PropertyType.Name.StartsWith("String"))
                {
                    Console.WriteLine("{0}:{1}", name, value);
                }
                else
                {
                    foreach (PropertyInfo itemsub in value.GetType().GetProperties())
                    {

                        PrintProperties(value);
                    }
                }
            }
        }
