调用Newtonsoft.Json 报FileNotFoundException 错误

具体如下：

Exception StackTrace at Newtonsoft.Json.Converters.BinaryConverter.CanConvert(Type objectType)
at Newtonsoft.Json.JsonSerializer.GetMatchingConverter(IList`1 converters, Type objectType)
at Newtonsoft.Json.Serialization.DefaultContractResolver.InitializeContract(JsonContract contract)
at Newtonsoft.Json.Serialization.DefaultContractResolver.CreateObjectContract(Type objectType)
at Newtonsoft.Json.Serialization.DefaultContractResolver.CreateContract(Type objectType)
at Newtonsoft.Json.Serialization.DefaultContractResolver.ResolveContract(Type type)
at Newtonsoft.Json.Serialization.JsonSerializerInternalWriter.Serialize(JsonWriter jsonWriter, Object value, Type objectType)
at Newtonsoft.Json.JsonSerializer.SerializeInternal(JsonWriter jsonWriter, Object value, Type objectType)
at Newtonsoft.Json.JsonConvert.SerializeObjectInternal(Object value, Type type, JsonSerializer jsonSerializer)
at Newtonsoft.Json.JsonConvert.SerializeObject(Object value)

而外部CATCH的是：FileNotFoundException

程序是.NET 2.0的，通过配置，运行在.NET 4.0下

<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v2.0.50727"/>
<supportedRuntime version="v4.0"/>
</startup>

当时系统盘只有700M左右空间，调试时一但用Json.Converter 就会报上面的错。

然后装了.NET FRAMEWORK 2.0 后就正常了。

可能是磁盘空间不足导致的问题。
