使用2.0 C＃驱动程序将DateTime保存到MongoDb时如何防止丢失精度？

Question

Currently when we are serializing and saving an object that contains a DateTime to MongoDb using the 2.0 C# Driver we are losing precision so when it is compared as part of a concurrency check it is failing as the ticks are different.

I found a blog post that describes how to maintain the precision using the original C# driver by using DateTimeSerializationOptions and specifying a BsonType of Document but I cannot find an example online of how to do this in the new version.

What is the equivalent for the code below in the new driver?

DateTimeSerializationOptions.Defaults = new DateTimeSerializationOptions(DateTimeKind.Utc, BsonType.Document);

在GitHub上挖掘了序列化程序的源代码后，我提出了以下工作原理。

BsonSerializer.RegisterSerializer(typeof(DateTime), new DateTimeSerializer(DateTimeKind.Utc, BsonType.Document))
