Serializing objects in C# 4.0, is there a simpler way?

When set up an object for 开发者_C百科serialization I do the following:

[Serializable]
public class ContentModel
{
    public int ContentId { get; set; }
    public string HeaderRendered { get; set; }

    public ContentModel()
    {
        ContentId = 0;
        HeaderRendered = string.Empty;
    }

    public ContentModel(SerializationInfo info, StreamingContext ctxt) 
    {
        ContentId = (int)info.GetValue("ContentId", typeof(int));
        HeaderRendered = (string)info.GetValue("HeaderRendered", typeof(string));
    }

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

It's quite exhausting when there are lots of properties. Is there a simpler or less verbose way of doing this in C# 4.0?

You don't need the extra constructor or the GetObjectData method unless you want to customize the serialization mechanism. If you have simple properties, the default serialization mechanism will handle them quite well. All you need is the Serializable attribute, and you're golden.

---

Why are you doing this by hand? BinaryFormatter already knows how to do this automatically. If filtering the fields is important then make another class that just stores the ones that you want to serialize.

---

You could also consider using DataContract serialization which makes it easy to output JSON or XML if you ever need that.

I'd like to add that since your class doesn't implement ISerializable, your custom GetObjectData method may never be called.
