CSFramework.AutoUpgrader 发布命令升级包出错：InvalidOperationException使用 XmlInclude 或 SoapInclude 特性静态指定非已知的类型

InvalidOperationException: 不应是类型 CSFramework.AutoUpgrader.CmdDeleteFile。使用 XmlInclude 或 SoapInclude 特性静态指定非已知的类型。

C# Code:

/// <summary>
/// 序列化对象
/// </summary>
/// <param name="o">对象</param>
/// <param name="outFile">持久化对象文件</param>
/// <returns></returns>
public static bool Serialize(object o, string outFile)
{
using (StringWriter sw = new StringWriter())
{
XmlSerializer xz = new XmlSerializer(o.GetType());
xz.Serialize(sw, o);
File.WriteAllText(outFile, sw.ToString(), Encoding.UTF8);
}

return true;
}

解决方案：

在PackageFile类添加XmlInclude特性，静态指定该类需要序列化的类型。

C# Code:

/// <summary>
/// 升级包实体类，用于序列化持久存储在数据库
/// </summary>
[Serializable]
[XmlInclude(typeof(PackageFileItem))]
[XmlInclude(typeof(CmdDeleteFile))]
[XmlInclude(typeof(CmdRunProgram))]
public class PackageFile
{
private string _PackingNo;
private string _Remark;
private List<PackageFileItem> _Files;

/// <summary>
/// 支持Serializable特性的默认无参数构造器
/// </summary>
public PackageFile()
{ }
}

MSDN关于XmlIncludeAttribute的定义如下：允许 XmlSerializer 在它序列化或反序列化对象时识别类型。
