我试图在创建对象的副本 silverligth 5 其中像IFormatters和IcCloanble接口不支持。 *

I was trying to create copy of objects in silverligth 5 where interfaces like IFormatters and IcCloanble do not support. *

我的对象是这样的：（请注意，这些obkjects是在反序列化XML获得）： 我试图做复制这样的：

My objects are like this: (Note that these obkjects are obtained on deserializing xml): I tried to do copy like this:

    [XmlRoot(ElementName = "component")]
        public class Component
        {
            [XmlElement("attributes")]
            public Attributes Attributes { get; set; } 

            [XmlIgnore]
            public Attributes atrbtOrginal = new Attributes();
            [XmlIgnore]
            public Attributes atrbtCopy{ get; set; }
        }
        public Component()
            {          
                atrbtCopy= atrbtOrginal ;
            } 

当然它不会工作，然后我得到这个code对seraching对谷歌：

Sure it will not work then i got this code on seraching on Google :

 public static class ObjectCopier
    {
        public static T Clone<T>(T source)
        {
            if (!typeof(T).IsSerializable)
            {
                throw new ArgumentException("The type must be serializable.", "source");
            }

            // Don't serialize a null object, simply return the default for that object
            if (Object.ReferenceEquals(source, null))
            {
                return default(T);
            }
            IFormatter formatter = new BinaryFormatter();
            Stream stream = new MemoryStream();
            using (stream)
            {
                formatter.Serialize(stream, source);
                stream.Seek(0, SeekOrigin.Begin);
                return (T)formatter.Deserialize(stream);
            }
        }

    }

And i thought of doing something liek this:

objectOrginal.Clone();.

但是，在silverligth5问题是：

But the problem in silverligth5 is :

Error   2   The type or namespace name 'BinaryFormatter' could not be found (are you missing a using directive or an assembly reference?)   
Error   1   The type or namespace name 'IFormatter' could not be found (are you missing a using directive or an assembly reference?)

有没有在Silverlight 5的任何选择。请详细解释一下。 非常感谢。

is there any alternative in Silverlight 5 . Please explain in detail. Thanks a lot.

推荐答案

实施DataContractSerializer的属性（DataContract，数据成员）在你的类和调用的DataContractSerializer将其序列化到一个MemoryStream，然后再次用它来序列化出的MemoryStream来该对象的新实例。到目前为止，最容易理解，而且相当高性能的了。

Implement the DataContractSerializer attributes (DataContract, DataMember) on your classes and call DatacontractSerializer to serialize it to a MemoryStream, then use it again to serialize out of the MemoryStream to a new instance of the object. By far the easiest to understand, and quite performant too.

类定义的例子：

[DataContract]
class MyClass
{
    [DataMember]
    public int MyValue {get;set;}
    [DataMember]
    public string MyOtherValue {get;set;}
}
