我有一个带有 System.Version 属性的类，它看起来像这样:
当我序列化类时，version 总是空的:
<Version />
客户端类如下所示:
[Serializable]
public class Client
{
public string Description;
public string Directory;
public DateTime ReleaseDate;
public Version Version;
}
最佳答案
System.Version不可序列化，如果您查看 it's properties on MSDN ，您会看到它们没有 setter ...因此序列化程序不会存储它们。然而，this approach still works .那篇文章(旧但仍然有效)提供了一个可序列化的 Version 类，你可以切换到那个并开始吗？

如何在ruby中调用C#dll？ 最佳答案 我能想到几种可能性:为您的DLL编写(或找人编写)一个COM包装器，如果它还没有，则使用Ruby的WIN32OLE库来调用它；看看RubyCLR,其中一位作者是JohnLam，他继续在Microsoft从事IronRuby方面的工作。(估计不会再维护了，可能不支持.Net2.0以上的版本)；正如其他地方已经提到的，看看使用IronRuby，如果这是您的技术选择。有一个主题是here.请注意，最后一篇文章实际上来自JohnLam(看起来像是2009年3月)，他似乎很自在地断言RubyCL
