以下代码示例演示如何序列化/反序列化为文件。我怎么能修改它来序列化为变量而不是文件? (假设变量将传递给读/写方法而不是文件名)。
public static void WriteObject(string fileName)
{
Console.WriteLine(
"Creating a Person object and serializing it.");
Person p1 = new Person("Zighetti", "Barbara", 101);
FileStream writer = new FileStream(fileName, FileMode.Create);
DataContractSerializer ser =
new DataContractSerializer(typeof(Person));
ser.WriteObject(writer, p1);
writer.Close();
}
public static void ReadObject(string fileName)
{
Console.WriteLine("Deserializing an instance of the object.");
FileStream fs = new FileStream(fileName,
FileMode.Open);
XmlDictionaryReader reader =
XmlDictionaryReader.CreateTextReader(fs, new XmlDictionaryReaderQuotas());
DataContractSerializer ser = new DataContractSerializer(typeof(Person));
// Deserialize the data and read it from the instance.
Person deserializedPerson =
(Person)ser.ReadObject(reader, true);
reader.Close();
fs.Close();
Console.WriteLine(String.Format("{0} {1}, ID: {2}",
deserializedPerson.FirstName, deserializedPerson.LastName,
deserializedPerson.ID));
}

您可以将FileStream
更改为内存流并将其转储到byte[]
。
public static byte[] WriteObject<T>(T thingToSave)
{
Console.WriteLine("Serializing an instance of the object.");
byte[] bytes;
using(var stream = new MemoryStream())
{
var serializer = new DataContractSerializer(typeof(T));
serializer.WriteObject(stream, thingToSave);
bytes = new byte[stream.Length];
stream.Position = 0;
stream.Read(bytes, 0, (int)stream.Length);
}
return bytes;
}
public static T ReadObject<T>(byte[] data)
{
Console.WriteLine("Deserializing an instance of the object.");
T deserializedThing = default(T);
using(var stream = new MemoryStream(data))
using(var reader = XmlDictionaryReader.CreateTextReader(stream, new XmlDictionaryReaderQuotas()))
{
var serializer = new DataContractSerializer(typeof(T));
// Deserialize the data and read it from the instance.
deserializedThing = (T)serializer.ReadObject(reader, true);
}
return deserializedThing;
}
