使用不同的名称通过Json.Net进行序列化和反序列化

使用不同的名称通过Json.Net进行序列化和反序列化

您可以使用

JsonSerializerSettings

，ContractResolver和NamingStrategy。

public class ErrorDetails{    public int Id { get; set; }    public string ErrorMessage { get; set; }}var json = "{'Id': 1,'error_message': 'An error has occurred!'}";

对于反序列化，您可以使用

SnakeCaseNamingStrategy

。

var dezerializerSettings = new JsonSerializerSettings{    ContractResolver = new DefaultContractResolver    {        NamingStrategy = new SnakeCaseNamingStrategy()    }};var obj = JsonConvert.DeserializeObject<ErrorDetails>(json, dezerializerSettings);

要再次序列化对象，您不必更改，

JsonSerializerSettings

因为默认情况下将使用属性名称。

var jsonNew = JsonConvert.SerializeObject(obj);

jsonNew =“ {‘Id’：1，’ErrorMessage’：’发生错误！’}”

或者，您可以创建合同解析器，该解析器可以决定要使用的名称。然后，您可以决定何时要对pascal大小写名称格式或带下划线的格式进行反序列化和序列化。

public class CustomContractResolver : DefaultContractResolver{    public bool UseJsonPropertyName { get; }    public CustomContractResolver(bool useJsonPropertyName)    {        UseJsonPropertyName = useJsonPropertyName;    }    protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization)    {        var property = base.CreateProperty(member, memberSerialization);        if (!UseJsonPropertyName) property.PropertyName = property.UnderlyingName;        return property;    }}public class ErrorDetails{    public int Id { get; set; }    [JsonProperty("error_message")]    public string ErrorMessage { get; set; }}var json = "{'Id': 1,'error_message': 'An error has occurred!'}";var serializerSettings = new JsonSerializerSettings(){    ContractResolver = new CustomContractResolver(false)};var dezerializerSettings = new JsonSerializerSettings{    ContractResolver = new CustomContractResolver(true)};var obj = JsonConvert.DeserializeObject<ErrorDetails>(json, dezerializerSettings);var jsonNew = JsonConvert.SerializeObject(obj, serializerSettings);

jsonNew =“ {‘Id’：1，’ErrorMessage’：’发生错误！’}”
