如果您无权访问用于更改属性的类,或者不想始终使用相同的重命名属性,则也可以通过创建自定义解析程序来重命名。
例如,如果您有一个名为 MyCustomObject
,具有一个名为的属性LongPropertyName
,则可以使用这样的自定义解析器…
public class CustomDataContractResolver : DefaultContractResolver
{
public static readonly CustomDataContractResolver Instance = new CustomDataContractResolver ();
protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization)
{
var property = base.CreateProperty(member, memberSerialization);
if (property.DeclaringType == typeof(MyCustomObject))
{
if (property.PropertyName.Equals("LongPropertyName", StringComparison.OrdinalIgnoreCase))
{
property.PropertyName = "Short";
}
}
return property;
}
}
然后调用序列化并提供解析器:
var result = JsonConvert.SerializeObject(myCustomObjectInstance,
new JsonSerializerSettings { ContractResolver = CustomDataContractResolver.Instance });
结果将缩短为 {“ Short”:“ prop value”}而不是{“ LongPropertyName”:“ prop value”}
