没有序列化XmlInclude [英] Serializing without XmlInclude

问题描述

我反序列化使用.NET序列化名为方法类。 方法包含 IAction 实施对象的列表。我原来使用的 [XmlInclude] 属性来指定执行 IAction 所有类。

但现在，我想改变我的程序加载目录中的所有DLL的并去掉其实现类 IAction 。然后，用户可以反序列化包含他们的行动实施 IAction 文件。

我不控制实现了这个类 IAction 了，所以我不能使用的 [XmlInclude]

有没有办法在运行时设置该属性？ ？或者有类似属性的实现类设置

  public类方法
 {
公开名单< Actions.IAction>操作=新的List< Actions.IAction>（）; 
} 
 
公共接口IAction 
 {
无效DoExecute（）; 
} 
 
公共静态类型[] LoadActionPlugins（字符串pluginDirectoryPath）
 {
名单，LT;类型> pluginTypes =新的List<类型和GT;（）; 
 
的String [] = filesInDirectory Directory.GetFiles（pluginDirectoryPath，* .DLL，SearchOption.TopDirectoryOnly）; 
的foreach（在filesInDirectory串pluginPath）
 {
 System.Reflection.Assembly actionPlugin = System.Reflection.Assembly.LoadFrom（pluginPath）; 
类型[] = assemblyTypes actionPlugin.GetTypes（）; 
的foreach（在assemblyTypes型型）
 {
型foundInterface = type.GetInterface（IAction）; 
如果（foundInterface！= NULL）
 {
 pluginTypes.Add（类型）; 
} 
} 
} 
 
返回pluginTypes.Count == 0？空：pluginTypes.ToArray（）; 
} 
  

解决方案

XmlSerializer的具有接受一个构造函数类型的数组反序列化时将被接受：

 公开的XmlSerializer（$ b $型b型，
型[] extraTypes 
）; 
  

您应该能够通过你的assemblyTypes作为第二个参数的数组。

I'm deserializing a class called Method using .NET Serialization. Method contains a list of objects implementing IAction. I originally used the [XmlInclude] attribute to specify all classes which implement IAction.

But now, I'd like to change my program to load all the dll's in a directory and strip out the classes which implement IAction. Then users can deserialize files which contain their actions implementing IAction.

I don't control the classes which implement IAction anymore, therefore I can't use [XmlInclude].

Is there a way to set this attribute at runtime? Or have a similar attribute set for the implementing class?

public class Method
{
    public List<Actions.IAction> Actions = new List<Actions.IAction>();
}

public interface IAction
{
    void DoExecute();
}

public static Type[] LoadActionPlugins(string pluginDirectoryPath)
{
    List<Type> pluginTypes = new List<Type>();

    string[] filesInDirectory = Directory.GetFiles(pluginDirectoryPath, "*.dll", SearchOption.TopDirectoryOnly);
    foreach (string pluginPath in filesInDirectory)
    {
        System.Reflection.Assembly actionPlugin = System.Reflection.Assembly.LoadFrom(pluginPath);
        Type[] assemblyTypes = actionPlugin.GetTypes();
        foreach (Type type in assemblyTypes)
        {
            Type foundInterface = type.GetInterface("IAction");
            if (foundInterface != null)
            {
                pluginTypes.Add(type);
            }
        }
    }

    return pluginTypes.Count == 0 ? null : pluginTypes.ToArray();
}

解决方案

XmlSerializer has a constructor that accepts an array of types that will be accepted when deserializing:

public XmlSerializer(
   Type type,
   Type[] extraTypes
);

You should be able to pass your array of assemblyTypes as the second argument.
