需要在序列化时候，忽略掉某些字段，对Newtonsoft.Json进行全局配置，如下：
1. 自定 ContractResolver
?public class MyContractResolver : DefaultContractResolver ???{ ???????protected override IList<JsonProperty> CreateProperties(Type type, MemberSerialization memberSerialization) ???????{ ???????????if (!typeof(EntityBase).IsAssignableFrom(type)) ???????????{ ???????????????return base.CreateProperties(type, memberSerialization); ???????????} ???????????IList<JsonProperty> props = base.CreateProperties(type, memberSerialization); ???????????foreach (var prop in props) ???????????{ ???????????????if (prop.DeclaringType.FullName != null && prop.DeclaringType.FullName.StartsWith("PWMIS.DataMap.Entity.EntityBase")) ???????????????{ ???????????????????prop.Ignored = true; ???????????????} ???????????} ???????????return props; ???????} ???}2. 应用程序启动的时候对JsonConvert进行默认配置：
???JsonSerializerSettings setting = new JsonSerializerSettings() ???????????{ ???????????????Formatting = Formatting.None, ???????????????ContractResolver = new MyContractResolver() ???????????}; ???????????JsonConvert.DefaultSettings = new Func<JsonSerializerSettings>(() => ???????????{ ???????????????//日期类型默认格式化处理 ???????????????setting.DateFormatHandling = Newtonsoft.Json.DateFormatHandling.MicrosoftDateFormat; ???????????????setting.DateFormatString = "yyyy-MM-dd HH:mm:ss"; ???????????????//空值处理 ???????????????setting.NullValueHandling = NullValueHandling.Ignore; ???????????????return setting; ???????????});
Newtonsoft.Json 全部配置
