Question

我有一个带有属性的类。我想知道我们是否可以设置属性，如 XmlAttributeAttribute.AttributeName。

这里ElementName属性是在编译时设置的，我想知道我们可以设置@运行时。

public class MyTestClass
{
    [XmlElement(ElementName = "MyAttributeName")]
    public int MyAttribute
    {
        get
        {
            return 23;
        }
    }
}

Answer 1

您正在寻找XmlAttributeOverrides。

  XmlAttributeOverrides attOv = new XmlAttributeOverrides();
  XmlAttributes attrs = new XmlAttributes();
  attrs.XmlElements.Add(new XmlElementAttribute("MyAttributeName"));
  attOv.Add(typeof(MyTestClass), "MyAttribute", attrs);
  XmlSerializer serializer = new XmlSerializer(typeof(MyTestClass), attOv);
  //...

Answer 2

您需要实现ISerializable接口并覆盖以下函数，您可以在运行时设置属性（从列表或您可能想要的任何其他方式）

public Employee(SerializationInfo info, StreamingContext ctxt)
{
    //Get the values from info and assign them to the appropriate properties

    EmpId = (int)info.GetValue("EmployeeId", typeof(int));
    EmpName = (String)info.GetValue("EmployeeName", typeof(string));
}

//Serialization function.

public void GetObjectData(SerializationInfo info, StreamingContext ctxt)
{
    //You can use any custom name for your name-value pair. But make sure you

    // read the values with the same name. For ex:- If you write EmpId as "EmployeeId"

    // then you should read the same with "EmployeeId"

    info.AddValue("EmployeeId", EmpId);
    info.AddValue("EmployeeName", EmpName);
}
