Question

我在Employee类之下。我需要从这个类生成一个xml，这样只允许一个属性。它是salary1或salary2。

如果来自Database的salary1大于Salary2，则生成的XML应该只包含salary1 XMLElement和salary2 XML Elment应该在生成的XML中不存在

现在我在生成的XML中获得了两个元素。

如果来自Database的salary2大于Salary1，则生成的XML应仅包含salary2 XMLElement和salary1 XML Elment应该在生成的XML中不存在。

我尝试过使用选择标识符，但我无法理解它。

    public class Employee

        public int Salary1 { get; set; }
        public int Salary2 { get; set; }

    }

       public static class Database

            public static int Salary1 = 100;
            public static int Salary2= 50;

    public static void Main(string[] args)

        XmlSerializer xsSubmit = new XmlSerializer(typeof(Employee));

        Employee subReq;
        if (Database.Salary1 > Database.Salary2)
        {
            subReq = new Employee { Salary1 = Database.Salary1 };
        }
        else
        {
            subReq = new Employee { Salary2 = Database.Salary2 };
        }
        var xml = "";

        using (var sww = new StringWriter())
        {
            using (XmlWriter writer = XmlWriter.Create(sww))
            {
                xsSubmit.Serialize(writer, subReq);
                xml = sww.ToString(); // Your XML
            }
        }

        Console.WriteLine(xml);
        Console.ReadLine();

    }
}

}

试试这个：

public class Employee
{
    private int salary;

    [XmlIgnore]
    public int Salary1 { get; set; }

    [XmlIgnore]
    public int Salary2 { get; set; }

    [XmlAttribute(AttributeName = "Salary")]
    public int SalaryToSerialize
    {
        get
        {
            salary = Math.Max(this.Salary1, this.Salary2);
            return salary;
        }
        set
        {
            salary = value;
        }    
    }
}

并按原样序列化对象。

希望它会对你有所帮助。

Answer 2

谢谢你们的回答和指导。但我的情况是因为某些原因我不能拥有像薪水这样的单一属性。从Int到String的数据类型解决问题

public static class Program
{

    public class Employee
    {

        public string Salary1 { get; set; }


        public string Salary2 { get; set; }





    }

    public static class Database
    {
        public static int? Salary1 = 100;
        public static int? Salary2 = 50;
    }

    public static void Main(string[] args)
    {

        XmlSerializer xsSubmit = new XmlSerializer(typeof(Employee));

        Employee subReq;
        if (Database.Salary1 > Database.Salary2)
        {
            subReq = new Employee { Salary1 = Database.Salary1.ToString() };
        }
        else
        {
            subReq = new Employee { Salary2 = Database.Salary2.ToString() };
        }
        var xml = "";

        using (var sww = new StringWriter())
        {
            using (XmlWriter writer = XmlWriter.Create(sww))
            {
                xsSubmit.Serialize(writer, subReq);
                xml = sww.ToString(); // Your XML
            }
        }

        Console.WriteLine(xml);
        Console.ReadLine();

    }

}
