oop典型应用,代码。
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 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;
}
