How to read and write data from an object type

Create a class to use as object type
​

public class MyFieldData : ObjectBase
{
    private string name;

    public string Name
    {
        get => name;
        set => name = this.ThrowIfReadOnly(value);
    }
}

Example on how to use the class when creating the field definition:

var fieldDefinition = new FieldDefinition<ProductArea>("MyObjectFieldId", SystemFieldTypeConstants.Object)
{
    MultiCulture = false,
    Option = new ObjectOption
    {
        EntityType = typeof(MyFieldData)
    }
};

_fieldDefinitionService.Create(fieldDefinition);

Example on how to use the class to read field data:

var baseProduct = new BaseProduct("my-id", _productFieldTemplate.SystemId);

baseProduct.Fields.AddOrUpdateValue("MyObjectFieldId", new MyFieldData
{
    Name = "My name"
});

var myField = baseProduct.Fields.GetValue<MyFieldData>("MyObjectFieldId");
myField.Name = "My updated name";
