c# - RavenDB:如何防止 $type 被保存到动态类型属性？

Question

有没有办法防止$type保存动态类型值时添加属性？

当我保存这个时:

new Activity {
    Name = "FormFieldDeleted",
    Body =  new {
        MyDeletedFormField(),
        MyCompleteForm()
    }
}

我明白了

<>f__AnonymousType1`2[[MyProject.Domains.Forms.Models.FormField, MyProject.Domains.Forms],[MyProject.Domains.Forms.Entities.FormRegistration, MyProject.Domains.Forms]], MyProject.Api.Forms

但是当我尝试获取这个保存的实体时，它会崩溃并出现以下异常。我知道它缺少项目引用，但我真的不想添加该引用(我不想从控制台应用程序引用 API)。我最好阻止 $type属性(property)。

/usr/local/share/dotnet/dotnet path/MyProject/MyProject/src/MyProject.Tasks.MapActivities/bin/Debug/netcoreapp3.1/MyProject.Tasks.MapActivities.dll
Unhandled exception. System.InvalidOperationException: Could not convert document 31317d58-db9e-4f60-8dee-b8593f3e06c0 to entity of type MyProject.Domains.Core.Entities.Activity
 ---> Newtonsoft.Json.JsonSerializationException: Error resolving type specified in JSON '<>f__AnonymousType1`2[[MyProject.Domains.Forms.Models.FormField, MyProject.Domains.Forms],[MyProject.Domains.Forms.Entities.FormRegistration, MyProject.Domains.Forms]], MyProject.Api.Forms'. Path 'Body.$type'.
 ---> Newtonsoft.Json.JsonSerializationException: Could not load assembly 'MyProject.Api.Forms'

是的，有办法。
您可以使用以下代码自定义序列化的工作方式:

store.Conventions.CustomizeJsonSerializer = serializer =>
{
   serializer.TypeNameHandling = Newtonsoft.Json.TypeNameHandling.None;
};

举个例子，看看这里的代码: https://dotnetfiddle.net/voJ7US
