序列化带有数组的对象

Question

I have this class :

[Serializable]
class Data
{
  int data1;
  int data2;
  Other_Data[] array;
}
class Other_Data
{
// I have some ints and bool here
}

The question is how do I serialize/deserialize a object of type Data with a single file

Answer 1

If the type Other_Data is serializable too, then this should cause you no problems. Just know that serializers require the types and properties or fields to be public:

[Serializable]
public class Data
{
    public int data1;
    public int data2;
    public Other_Data[] array;
}

[Serializable]
public class Other_Data
{
    public int someInt;
    public bool someBool;
}

And then for example using the XmlSerializer :

var obj = new Data() {
    data1 = 5,
    data2 = 7,
    array = new Other_Data[] {
        new Other_Data() { someInt = 1, someBool = true },
        new Other_Data() { someInt = 2, someBool = true },
        new Other_Data() { someInt = 3, someBool = false }
    }
};

var xmlSerializer = new XmlSerializer(typeof(Data));
var stringWriter = new StringWriter();
xmlSerializer.Serialize(stringWriter, obj);

Console.WriteLine(stringWriter.ToString());
