c# - Can I change the Type discriminator property in MongoDB?

Question

I am having trouble moving between mongodb and json.net due to polymorphic types. the c# mongodb driver users _t as the discriminator property name and json.net uses $type. I know json.net has this value hardcoded from other research. My question is if anyone knows of a way to rename "_t" to "$type" using the c# mongodb driver?

我相信您可以创建自定义鉴别器约定，并且可以将其添加到您希望修改的每种类型中；

这是一个可能对您有所帮助的自定义鉴别器约定的示例；
