c# - 在 C# 中序列化和反序列化自定义异常

Question

我目前正在处理异常，我已经创建了一个实现父异常类的自定义异常。

当我尝试对此类自定义异常进行序列化或反序列化时出现问题。

错误如下:“System.Runtime.Serialization.SerializationException: 'Member 'InnerException' was not found.'”

我引用了互联网上的许多资源，但无法解决问题。我将代码附加到此正文中。

[Serializable]
public class CustomException : Exception
{
    public const string DefaultExceptionDescription = "temp";

    public string ExceptionDescription { get; set; }

    public string ReferenceId { get; private set; } = "temp";

    public CustomException(string ExceptionDescription = DefaultExceptionDescription)
    {
        ExceptionDescription = ExceptionDescription;
    }

    [SecurityPermission(SecurityAction.Demand, SerializationFormatter = true)]
    protected CustomException(SerializationInfo info, StreamingContext context) : base(info, context)
    {
        if (info != null)
        {
            ExceptionDescription = info.GetString(nameof(ExceptionDescription));
            ReferenceId = info.GetString(nameof(ReferenceId));
        }
    }

    [SecurityPermission(SecurityAction.Demand, SerializationFormatter = true)]
    public override void GetObjectData(SerializationInfo info, StreamingContext context)
    {
        if (info != null)
        {
            info.AddValue(nameof(ExceptionDescription), ExceptionDescription);
            info.AddValue(nameof(ReferenceId), ReferenceId);
        }

        base.GetObjectData(info, context);
    }
}

提前致谢!!!

The common language runtime throws SerializationException if any type in the graph of objects being serialized does not have the SerializableAttribute attribute applied.

尝试删除 SerializableAttribute
