如何在C#中序列化Exception对象？

在C#中序列化Exception对象，可以使用以下方法：

使用BinaryFormatter进行序列化和反序列化

using System;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;

public static class ExceptionExtensions
{
    public static byte[] Serialize(this Exception exception)
    {
        using var memoryStream = new MemoryStream();
        var binaryFormatter = new BinaryFormatter();
        binaryFormatter.Serialize(memoryStream, exception);
        return memoryStream.ToArray();
    }

    public static Exception Deserialize(this byte[] serializedException)
    {
        using var memoryStream = new MemoryStream(serializedException);
        var binaryFormatter = new BinaryFormatter();
        return (Exception)binaryFormatter.Deserialize(memoryStream);
    }
}

使用DataContractSerializer进行序列化和反序列化

using System;
using System.IO;
using System.Runtime.Serialization;

public static class ExceptionExtensions
{
    public static byte[] Serialize(this Exception exception)
    {
        using var memoryStream = new MemoryStream();
        var dataContractSerializer = new DataContractSerializer(typeof(Exception));
        dataContractSerializer.WriteObject(memoryStream, exception);
        return memoryStream.ToArray();
    }

    public static Exception Deserialize(this byte[] serializedException)
    {
        using var memoryStream = new MemoryStream(serializedException);
        var dataContractSerializer = new DataContractSerializer(typeof(Exception));
        return (Exception)dataContractSerializer.ReadObject(memoryStream);
    }
}

使用Json.NET进行序列化和反序列化

using System;
using Newtonsoft.Json;

public static class ExceptionExtensions
{
    public static string Serialize(this Exception exception)
    {
        return JsonConvert.SerializeObject(exception);
    }

    public static Exception Deserialize(this string serializedException)
    {
        return JsonConvert.DeserializeObject<Exception>(serializedException);
    }
}

以上三种方法都可以实现Exception对象的序列化和反序列化，可以根据具体需求选择合适的方法。
