C# JsonConvert.SerializeObject在windows Xp sp3中崩溃
我正在使用Newtonsoft json工具进行序列化和反序列化C# JsonConvert.SerializeObject在windows Xp sp3中崩溃,c#,json,c#-4.0,json.net,C#,Json,C# 4.0,Json.net,我正在使用Newtonsoft json工具进行序列化和反序列化 JsonConvert.SerializeObject(NodeConfigurator.Instance, Formatting.None, new JsonSerializerSettings() { ReferenceLoopHandling = ReferenceLoopHandling.Ignore }); 它在windows 7及以上版本中运行良好，但在windows xp sp3中，它给出了“Newton
JsonConvert.SerializeObject(NodeConfigurator.Instance, Formatting.None, new JsonSerializerSettings()
{
ReferenceLoopHandling = ReferenceLoopHandling.Ignore
});

这里是属性…我认为您应该修改您的类，将其序列化并向导致循环引用的成员添加
[JsonIgnore]有关
[JsonIgnore]Console.WriteLine（“Json.NET版本：”+typeof（JsonSerializer.Assembly.FullName）。我已经执行了&它是Newtonsoft.Json，版本=7.0.0.0，区域性=neutral，PublicKeyToken=null。在“修复-修复了使用有效类型转换器反序列化接口的错误”中修复了一个错误。因此，如果您在XP机器上使用的版本比该版本旧，则可能导致崩溃。@dbc我已通过将JsonIgnore放入relaycommand中修复了此问题。现在它没有崩溃。我也尝试过此操作，但仍然会遇到相同的异常。可能这不是循环引用问题。您是否检查了两个操作系统上的库版本？你能输出你在W7上收到的序列化字符串吗？我已经在windows 7Ya中发布了输出，我已经检查过了。我已经使用.net 4.0开发了应用程序，我已经添加了相应的dll 7.0.0.0版本&运行时版本是v4.0.30319
