C# 列表<；MyObject>；无法序列化

public int-Eight{get{返回此值。Eight；}set{if（value>=0&&value=0&&value=0&&value=0&&value=0&&value使用此代码，您将出现编译时错误，因为无法将[Serializable]属性应用于属性：

    [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
答案如下所示：


我所要做的就是重新启动Visual Studio，然后重新构建所有内容。
您忘记在Serialize（）调用中添加所有必需的类型了吗

此代码适用于您的所有类：

    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();
    }

static void Main（字符串[]args）
{
SiteBinding s=新的SiteBinding（）；
s、 ip=新绑定ip（“127.0.0.1:8080”）；
s、 type=新的BindingType（）；
WebSiteSettings集合=新的WebSiteSettings（）；
set.credentials=新站点凭据（）；
set.bindings=new List（）{s}；
XmlSerializer ser=新的XmlSerializer（sets.GetType（））；
序列化（新的System.IO.MemoryStream（），集合）；
Console.Read（）；
}
请参见下面我的“自己的答案”…代码一开始就没有问题…VisualStudio IDE出现了问题。在我重新启动它之后，一切都按照原来的方式编译…也就是说，甚至不需要一个
[Serializable]
属性，因为它本来就应该是这样的…但是谢谢：）
    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();
    }
