遍历获得一个实体类的所有属性名,以及该类的所有属性的值
//先定义一个类:

public class User
{
  public string name { get; set; }
  public string gender { get; set; }
  public string age { get; set; }
}
//实例化类,并给实列化对像的属性赋值:

User u = new User();
u.name = "ahbool";
u.gender = "男";

//输出此类的所有属性名和属性对应的值

Response.Write(getProperties(u));

//输出结果为: name:ahbool,gender:男,age:,

//遍历获取类的属性及属性的值:

public string getProperties(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;
}
