设置属性@运行时间

Question

我有一个有属性的类，我想知道是否可以设置属性，如 XmlAttributeAttribute.AttributeName。

这里的ElementName属性是在编译时设置的，我想知道我们能不能设置@运行时间。

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

您将需要实现ISerializable接口，并覆盖以下功能，可以在其中设置在运行时（你可能想从列表或任何其他方式）的属性

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); 
}
