This thing is something new .NET Framework 4.5 ..
found that this is probably just as excited discovered the New World, let me praise God .. Anders Hejlsberg once again
here are MSDN: http://msdn.microsoft.com/en -us / library / system.dynamic.expandoobject.aspx
simply look at his convenient place ..
I build an object:
1.
public class Product
2.
{
3.
public string Name { get; set; }
4.
}
This time if I was in 'implementation period', the need to add a dynamic property of ..
called the Description how to do it?!
01.
/// <summary>
02.
/// 转成可以扩充的对象
03.
/// </summary> www.it165.net
04.
/// <param name="obj"></param>
05.
/// <returns></returns>
06.
public dynamic ConvertToDynamic(object obj)
07.
{
08.
IDictionary<string, object> result = new ExpandoObject();
09.
10.
foreach (PropertyDescriptor pro in TypeDescriptor.GetProperties(obj.GetType()))
11.
{
12.
result.Add(pro.Name, pro.GetValue(obj));
13.
}
14.
15.
return result as ExpandoObject;
16.
}
I will write an original method of Product objects, turn into Key Value patterns turn into ExpandoObject
then you can add a new property in the 'implementation period' ..
01.
Product p1 = new Product();
02.
p1.Name = "商品名称";
03.
04.
05.
dynamic exProd = ConvertToDynamic(p1);
06.
//下面两个属性都是 在执行期可被扩充出来的
07.
exProd.Description = "叙述";
08.
exProd.NewProperty1 = "我是新属性";
09.
10.
Response.Write(exProd.Name + "," + exProd.Description + "," + exProd.NewProperty1);
result:
It really expanded in the above, are very useful things ...
