强制XML序列化序列化只读属性 [英] Force XML serialization to serialize readonly property

问题描述

在C＃中，我有一个具有衍生性质应该通过XML序列化类。然而，XML序列化（默认）不序列读取=仅属性。我可以解决这个定义，像这样一个空的setter：

In C#, I have a class which has a derived property that should be serialized via XML. However, XML serialization (by default) doesn't serialize read=only properties. I can work around this by defining an empty setter like so:

public virtual string IdString
{
    get { return Id.ToString("000000"); }
    set { /* required for xml serialization */ }
}

但有一个更清洁更语义正确的方式，总之我自己写了ISerializable实现？

But is there a cleaner more semantically correct way, short of writing my own ISerializable implementation?

推荐答案

老实说这似乎并不算太​​坏对我来说，只要它是记录

Honestly this doesn't seem too bad to me as long as it is documented

您或许应该抛出一个异常，如果setter方法​​实际上是所谓的：

You should probably throw an exception if the setter is actually called:

/// <summary>
/// Blah blah blah.
/// </summary>
/// <exception cref="NotSupportedException">Any use of the setter for this property.</exception>
/// <remarks>
/// This property is read only and should not be set.  
/// The setter is provided for XML serialisation.
/// </remarks>
public virtual string IdString
{
    get
    {
        return Id.ToString("000000");
    }
    set
    {
        throw new NotSupportedException("Setting the IdString property is not supported");
    }
}
