列表<MyObject>未能序列化

Question

出于某种原因，用下面的代码：
[编辑]更新后的代码按建议...仍然给我同样的错误。

我得到这个错误，当我尝试建立：

 
Code generation for property 'bindings' failed. Error was: 'Type 
'MyLibrary.SiteBinding' in Assembly 'MyLibrary, Version=1.0.0.0, 
Culture=neutral, PublicKeyToken=null' is not marked as serializable.' 

这究竟是为什么？我真的不明白这一点。请帮忙。

Answer 1

的答案如下，在这里找到：

http://www.codeproject.com/Questions/128351/Code-generation-for-property-yyy-failed

所有我要做的就是重新启动Visual Studio，然后一切重新建造。

Answer 2

有了这个代码，你会得到编译时错误，因为你不能申请[Serializable]属性的属性：

[Serializable] 
    public class SiteBinding 
    { 
     public BindingType type { get; set; } 
     public string hostName { get; set; } 
     public int? port { get; set; } 
     [Serializable] //remove this line 
     public BindingIP ip { get; set; } 
     public string sslCertificate { get; set; } 
    } 

您应该删除属性

Answer 3

您忘记在Serialize（）调用中添加所有需要的类型吗？

此代码对我的作品与您的所有类：

static void Main(string[] args) 
    { 

     SiteBinding s = new SiteBinding(); 
     s.ip = new BindingIP("127.0.0.1:8080"); 
     s.type = new BindingType(); 
     WebSiteSettings sets = new WebSiteSettings(); 
     sets.credentials = new SiteCredential(); 
     sets.bindings = new List<SiteBinding>() {s}; 
     XmlSerializer ser = new XmlSerializer(sets.GetType()); 
     ser.Serialize(new System.IO.MemoryStream(),sets); 

     Console.Read(); 
    }
