使用json.net大小限制序列化数据？

JsonSerializerSettings settings = new JsonSerializerSettings
{
    MaxDepth = 20
};

string json = JsonConvert.SerializeObject(obj, settings);

JsonSerializerSettings settings = new JsonSerializerSettings
{
    Formatting = Formatting.Indented,
    MaxSerializationDepth = 20
};

string json = JsonConvert.SerializeObject(obj, settings);

JsonSerializerSettings settings = new JsonSerializerSettings
{
    ReferenceLoopHandling = ReferenceLoopHandling.Ignore
};

string json = JsonConvert.SerializeObject(obj, settings);

JsonSerializerSettings settings = new JsonSerializerSettings
{
    PreserveReferencesHandling = PreserveReferencesHandling.Objects
};

string json = JsonConvert.SerializeObject(obj, settings);

JsonSerializerSettings settings = new JsonSerializerSettings
{
    StringEscapeHandling = StringEscapeHandling.EscapeNonAscii
};

string json = JsonConvert.SerializeObject(obj, settings);
