Serialize object along with static member variable

Question

This question already has an answer here:

• Serialize a Static Class? 6 answers

I have the following object that contains a static member variable.

What I would like to do is serialize this object and save it to XML. Unfortunately, the code below does not seem to do the job.

I would appreciate any help in getting this working please.

[Serializable]
public class Numbers
{
    public int no;
    public static int no1;
    public SubNumbers SubNumber;
}

[Serializable]
public class SubNumbers
{
    public int no;
    public static int no2;
}

[TestMethod]
public void Serialize_Object_with_Static_Property_test()
{
    Numbers a = new Numbers();
    a.no = 12;
    Numbers.no1 = 345243;
    SubNumbers s = new SubNumbers();
    s.no = 459542; 
    SubNumbers.no2 = 9999999;
    a.SubNumber = s;
    String filename = @"a1.txt";
    FileStream fs = new FileStream(filename, FileMode.Open);
    XmlSerializer x = new XmlSerializer(typeof(Numbers));
    x.Serialize(fs, a); 
    fs.Close(); 
}

With Serialization, we can only serialize properties that are:

• Public
• Not static
• Not read Only

In this case, if you want to serialize "no1", you must wrap it, like this:

[Serializable]
public class Numbers
{
    public int no;
    public static int no1;
    public SubNumbers SubNumber;

    public int no1_Serialize {get {return no1;} set {no1 = value;} }
}
