如何在 RavenDB 序列化过程中忽略属性

Question

使用RavenDB 6，如何防止特定属性序列化到数据库。我已经尝试过

[JsonIgnore]

，但没用。

要自定义序列化，您可以将 序列化约定 添加到文档存储初始化中。
例如：

按照约定初始化文档存储：

using (var store = new DocumentStore()
{
    Conventions =
    {
        // customizations go here
        Serialization = new NewtonsoftJsonSerializationConventions
        {                     
            JsonContractResolver = new CustomJsonContractResolver()
        }
     }
}.Initialize())
{
   // rest of client logic code
}

自定义解析器：

public class CustomJsonContractResolver : DefaultContractResolver
{
    protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization)
    {
         JsonProperty property = base.CreateProperty(member, memberSerialization);

         // Check if the property should be ignored
         if (ShouldIgnoreProperty(property))
         {
               property.ShouldSerialize = instance => false; // Prevent serialization
         }

          return property;
     }

      private bool ShouldIgnoreProperty(JsonProperty property)
      {
         // Add logic to determine if the property should be ignored
         // For example, by property name:
         // Adjust the property name as needed
         return property.PropertyName == "PrpertyNameToIgnore";
      }
}
