How to serialize non-static child class of static class

Question

I want to serialize a pretty ordinary class, but the catch is it\'s nested in a static class like this:

public static class StaticClass
{
    [Serializable]
         


        

Answer 1

Either make the class non nested or consider using the DataContractSerializer instead.

Answer 2

As a pragmatic workaround - don't mark the nesting type static:

public class ContainerClass
{
    private ContainerClass() { // hide the public ctor
        throw new InvalidOperationException("no you don't");
    }

    public class SomeType
    {
        ...
    }
}

Answer 3

It's know limitation in XmlSerializer ()

And workaround is to use DataContractSerializer (DataContractAttribute + DataMemberAttribute)

var ser = new DataContractSerializer(typeof (StaticClass.SomeType));
var obj = new StaticClass.SomeType {Int = 2};
ser.WriteObject(stream, obj);

...

static class StaticClass
{
    [DataContract]
    public class SomeType
    {
        [DataMember]
        public int Int { get; set; }
    }
}

As you can see DataContractSerializer doesn't even require StaticClass to be public. One difference is that you should use WriteObject' andReadObject' instead Serialize and Deserialize
