序列化对象的XElement和内存中反序列化 [英] Serialize an object to XElement and Deserialize it in memory

问题描述

我想序列化对象到XML，但我不希望将其保存在磁盘上。我想抱着它在的XElement变量（LINQ的使用），然后反序列化回我的对象​​。

I want to serialize an object to XML, but I don't want to save it on the disk. I want to hold it in a XElement variable (for using with LINQ), and then Deserialize back to my object.

我怎样才能做到这一点？

How can I do this?

推荐答案

您可以使用这两个扩展方法序列化和的XElement和你的对象之间的反序列化。

You can use these two extension methods to serialize and deserialize between XElement and your objects.

public static XElement ToXElement<T>(this object obj)
{
    using (var memoryStream = new MemoryStream())
    {
        using (TextWriter streamWriter = new StreamWriter(memoryStream))
        {
            var xmlSerializer = new XmlSerializer(typeof(T));
            xmlSerializer.Serialize(streamWriter, obj);
            return XElement.Parse(Encoding.ASCII.GetString(memoryStream.ToArray()));
        }
    }
}

public static T FromXElement<T>(this XElement xElement)
{
        var xmlSerializer = new XmlSerializer(typeof(T));
        return (T)xmlSerializer.Deserialize(xElement.CreateReader());
}

用法

XElement element = myClass.ToXElement<MyClass>();
var newMyClass = element.FromXElement<MyClass>();
