是否可以使用
JSON.NET序列化静态属性,而无需为每个属性添加[JsonProperty]属性.
示例类:
示例类:
public class Settings { public static int IntSetting { get; set; } public static string StrSetting { get; set; } static Settings() { IntSetting = 5; StrSetting = "Test str"; } }
预期结果:
{ "IntSetting": 5,"StrSetting": "Test str" }
默认行为会跳过静态属性:
var x = JsonConvert.SerializeObject(new Settings(),Formatting.Indented);
解决方法
您可以使用自定义合约解析程序执行此操作.具体来说,您需要子类DefaultContractResolver并覆盖GetSerializableMembers函数:
public class StaticPropertyContractResolver : DefaultContractResolver { protected override List<MemberInfo> GetSerializableMembers(Type objectType) { var baseMembers = base.GetSerializableMembers(objectType); PropertyInfo[] staticMembers = objectType.GetProperties(BindingFlags.Static | BindingFlags.Public); baseMembers.AddRange(staticMembers); return baseMembers; } }
这里我们所做的就是调用GetSerializableMembers的基本实现,然后将公共静态属性添加到要序列化的成员列表中.
要使用它,您可以创建一个新的JsonSerializerSettings对象,并将ContractResolver设置为StaticPropertyContractResolver的一个实例:
var serializerSettings = new JsonSerializerSettings(); serializerSettings.ContractResolver = new StaticPropertyContractResolver();
现在,将这些设置传递给JsonConvert.SerializeObject,一切都应该工作:
string json = JsonConvert.SerializeObject(new Settings(),serializerSettings);
输出:
{ "IntSetting": 5,"StrSetting": "Test str" }
