使用 DataContractSerializer 时遇到问题

发布于 2024-09-07 14:21:45 字数 752 浏览 5 评论 0原文

我在使用 DataContractSerializer 序列化不可变实例时遇到问题，因为我正在序列化的类的属性缺少设置器。问题是我只想序列化实例（只是为了将其写入日志），并且我永远不需要反序列化它。有没有办法绕过这种行为？

我试图序列化的类：

[DataContract]
public class Person
{
    private readonly string _name;

    [DataMember]
    public string Name
    {
        get { return _name; }
    }

    public Person(string name)
    {
        _name = name;
    }
}

用于序列化该类的代码：

public string Serialize()
{
    var serializer = new DataContractSerializer(typeof(Person));
    StringBuilder stringBuilder = new StringBuilder();
    using (XmlWriter writer = XmlWriter.Create(stringBuilder)) {
        serializer.WriteObject(writer, this);
    }
    return stringBuilder.ToString();
}

I'm having trouble serializing an immutable instance with the DataContractSerializer, since the properties on the class I'm serializing is missing setters. The problem is that I only want to serialize the instance (just so it can be written to a log), and I will never need to deserialize it. Is there a way to bypass this behavior?

The class I'm trying to serialize:

[DataContract]
public class Person
{
    private readonly string _name;

    [DataMember]
    public string Name
    {
        get { return _name; }
    }

    public Person(string name)
    {
        _name = name;
    }
}

The code used for serializing the class:

public string Serialize()
{
    var serializer = new DataContractSerializer(typeof(Person));
    StringBuilder stringBuilder = new StringBuilder();
    using (XmlWriter writer = XmlWriter.Create(stringBuilder)) {
        serializer.WriteObject(writer, this);
    }
    return stringBuilder.ToString();
}

您可以将 [DataMember] 放在字段上，从而允许您拥有属性 getter。这些字段仍然可以是私有的。但是它不能是只读的，因为它需要构造对象然后设置字段。

[编辑]
这将导致使用字段名称，除非您使用 [DataMember(Name = "Name1")]

此版本使用 ISerialized 属性而不是 [DataContract]。
我不知道这将如何影响可操作性，但不需要公共设置器。

[Serializable]
public class Person : ISerializable
{
    private readonly string _name;

    public string Name
    {
        get { return _name; }
    }

    public Person(string name)
    {
        _name = name;
    }

    public string Serialize()
    {
        DataContractSerializer serializer = new DataContractSerializer(typeof(Person));
        System.Text.StringBuilder stringBuilder = new System.Text.StringBuilder();
        using (System.Xml.XmlWriter writer = System.Xml.XmlWriter.Create(stringBuilder))
        {
            serializer.WriteObject(writer, this);
        }
        return stringBuilder.ToString();
    }

    public void GetObjectData(SerializationInfo info, StreamingContext context)
    {
        info.AddValue("Name", _name);
    }
}

This version uses the ISerializable attribute instead of [DataContract].
I don't know how this will affect operability, but does not need a public setter.

[Serializable]
public class Person : ISerializable
{
    private readonly string _name;

    public string Name
    {
        get { return _name; }
    }

    public Person(string name)
    {
        _name = name;
    }

    public string Serialize()
    {
        DataContractSerializer serializer = new DataContractSerializer(typeof(Person));
        System.Text.StringBuilder stringBuilder = new System.Text.StringBuilder();
        using (System.Xml.XmlWriter writer = System.Xml.XmlWriter.Create(stringBuilder))
        {
            serializer.WriteObject(writer, this);
        }
        return stringBuilder.ToString();
    }

    public void GetObjectData(SerializationInfo info, StreamingContext context)
    {
        info.AddValue("Name", _name);
    }
}
