我是否可以序列化可序列化对象的通用列表,而无需指定其类型.

像下面破坏的代码背后的意图:

List<ISerializable> serializableList = new List<ISerializable>();

XmlSerializer xmlSerializer = new XmlSerializer(serializableList.GetType());

serializableList.Add((ISerializable)PersonList);

using (StreamWriter streamWriter = System.IO.File.CreateText(fileName))
{
    xmlSerializer.Serialize(streamWriter, serializableList);
}

编辑:

对于那些想要了解详细信息的人:当我尝试运行此代码时,它在XMLSerializer [...]行上出错:

无法序列化System.Runtime.Serialization.ISerializable接口.

如果我改变List<object>我得到"There was an error generating the XML document.".InnerException的细节是"{"The type System.Collections.Generic.List1[[Project1.Person, ConsoleFramework, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]] may not be used in this context."}"

person对象定义如下:

[XmlRoot("Person")]
public class Person
{
    string _firstName = String.Empty;
    string _lastName = String.Empty;

    private Person()
    {
    }

    public Person(string lastName, string firstName)
    {
        _lastName = lastName;
        _firstName …

我正在反序列化一个名为Method.NET Serialization 的类.Method包含实现的对象列表IAction.我最初使用该[XmlInclude]属性来指定实现的所有类IAction.

但是现在,我想改变我的程序来加载目录中的所有dll并删除实现的类IAction.然后,用户可以反序列化包含其实施的操作的文件IAction.

我不再控制实现的类IAction,因此我无法使用[XmlInclude].

有没有办法在运行时设置此属性？或者为实现类设置了类似的属性？

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 …
