遍历类的属性

 Response.Write(getProperties(l1.Quote)); //项目中的代码。这样也没有遍历所有的 属性的属性吧，，

 public string getProperties<T>(T t)
    {
        string tStr = string.Empty;
        if (t == null)
        {
            return tStr;
        }
        System.Reflection.PropertyInfo[] properties = t.GetType().GetProperties(System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.Public);

        if (properties.Length <= 0)
        {
            return tStr;
        }
        foreach (System.Reflection.PropertyInfo item in properties)
        {
            string name = item.Name;
            object value = item.GetValue(t, null);
            if (item.PropertyType.IsValueType || item.PropertyType.Name.StartsWith("String"))
            {
                tStr += string.Format("{0}:{1},", name, value);
            }
            else
            {
               getProperties(value);
            }
        }
        return tStr;
    }
