我有一个 WCF 服务，它包含它的接口、类定义和一些其他对象类。它编译得很好，但是当我运行它时，我得到：

Type 'sarus.division.warehouse.cmms.infrastructure.data.logic.location.type.Type' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute.  If the type is a collection, consider marking it with the CollectionDataContractAttribute.  See the Microsoft .NET Framework documentation for other supported types.

我的sarus.division.warehouse.cmms.infrastructure.data.logic.location.type.Type班级也有一个属性[Serializable]。但无论我做了什么，我都无法成功。

我怎样才能完成将此类设置为可序列化？有没有办法实现这个？

从您的代码：

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Type" in code, svc and config file together.
// NOTE: In order to launch WCF Test Client for testing this service, please select Type.svc or Type.svc.cs at the Solution Explorer and start debugging.
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Type : IType
{
   ....
}

我在这里看不到[Serializable]属性。并根据您的错误：

无法序列化类型“ sarus.division.warehouse.cmms.infrastructure.data.logic.location.type.Type ”。考虑使用 DataContractAttribute 属性对其进行标记，并使用 DataMemberAttribute 属性标记您想要序列化的所有成员。如果该类型是一个集合，请考虑使用 CollectionDataContractAttribute 对其进行标记。有关其他支持的类型，请参阅 Microsoft .NET Framework 文档。

这是它抱怨的班级。

答案就在您的错误消息中。[Serializable]根据所使用的序列化代码，可能无法正常工作。尝试按照建议标记您的类和属性。此外，任何被序列化的东西也需要被标记，所以你需要对你的Location班级进行同样的标记。

namespace sarus.division.warehouse.cmms.infrastructure.data.logic.location.type
{
    [DataContract]
    public class Type : actual.Actual
    {
        [DataMember]
        public List<location.Location> Locations { get; set; }

        ...
    }
}
