问题描述：Net5.0已经出来有段时间了，就琢磨的项目升级到5.0试一试的，按照方法，把项目sdk版本修改完后基本就算升级成功了，但是有个Redis序列化的方法有警告，提示这个
警告 SYSLIB0011 “BinaryFormatter.Serialize(Stream, object)”已过时:“BinaryFormatter serialization is obsolete and should not be used. See https://aka.ms/binaryformatter for more information.”
打开微软的说明页面，大概意思就是随便将泛型的数据写入和读取内存，存在风险隐患。
解决方案：按照微软的提示，将方法换一下就哦了
/// <summary> /// 序列化 /// </summary> /// <param name="obj"></param> /// <returns></returns> private static byte[] Serialize(object obj) { if (obj == null) return null; using var memoryStream = new MemoryStream(); DataContractSerializer ser = new DataContractSerializer(typeof(object)); ser.WriteObject(memoryStream, obj); var data = memoryStream.ToArray(); return data; } /// <summary> /// 反序列化 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="data"></param> /// <returns></returns> private static T Deserialize<T>(byte[] data) { if (data == null) return default(T); using var memoryStream = new MemoryStream(data); XmlDictionaryReader reader = XmlDictionaryReader.CreateTextReader(memoryStream, new XmlDictionaryReaderQuotas()); DataContractSerializer ser = new DataContractSerializer(typeof(T)); var result = (T)ser.ReadObject(reader, true); return result; }
有个问题，就是要序列化的类，必须多加几个处理，比如下面这样，当然不能保证我的解决办法就是最优的。。。
[Serializable] [KnownType(typeof(AuthorizeActionModel))] [DataContract(Name = "Customer", Namespace = "http://www.contoso.com")] public class AuthorizeActionModel : IExtensibleDataObject { /// <summary> /// 菜单编号 /// </summary> [DataMember] public string SysModuleId { set; get; } /// <summary> /// 链接地址 /// </summary> [DataMember] public string PageLink { set; get; } private ExtensionDataObject extensionData_Value; public ExtensionDataObject ExtensionData { get { return extensionData_Value; } set { extensionData_Value = value; } } }
再附带一个小问题，就是docker镜像路径的变化
- docker pull mcr.microsoft.com/dotnet/core/aspnet:3.1 + docker pull mcr.microsoft.com/dotnet/aspnet:5.0
