C# 将所有日期存储为BsonDocuments

我觉得这是可能的,但我似乎找不到。我想将我的mongo驱动程序配置为将任何
DateTime
对象存储为BsonDocument

mongo c#驱动程序允许您在全局范围内设置某些约定,这样您就不需要对所有内容进行注释,日期-时间选项也可以这样做吗

例如,我想删除以下注释:

[BsonDateTimeOptions(Representation=BsonType.Document)]


从我的所有
DateTime
属性。有人能给我指出正确的方向吗?

早就应该这样做了,但答案是使用约定打包和设置

ConventionRegistry.Register(
            "Dates as utc documents",
            new ConventionPack
            {
                new MemberSerializationOptionsConvention(typeof(DateTime), new DateTimeSerializationOptions(DateTimeKind.Utc, BsonType.Document)),
            },
            t => true);

早该这么做了,但答案是使用约定打包和设置

ConventionRegistry.Register(
            "Dates as utc documents",
            new ConventionPack
            {
                new MemberSerializationOptionsConvention(typeof(DateTime), new DateTimeSerializationOptions(DateTimeKind.Utc, BsonType.Document)),
            },
            t => true);

当我试图验证devshorts提供的答案是否有效时,我得到了一个编译时错误(因为ConventionPack的Add方法(由集合初始值设定项语法调用)需要一个IConvention

建议的解决方案几乎正确,只需稍加修改:

ConventionRegistry.Register(
    "dates as documents",
    new ConventionPack
    {
        new DelegateMemberMapConvention("dates as documents", memberMap =>
        {
            if (memberMap .MemberType == typeof(DateTime))
            {
                memberMap .SetSerializationOptions(new DateTimeSerializationOptions(DateTimeKind.Utc, BsonType.Document));
            }
        }),
    },
    t => true);
如果我们需要在多个地方使用此约定,我们可以将其打包到一个类中,如下所示:

public class DateTimeSerializationOptionsConvention : ConventionBase, IMemberMapConvention
{
    private readonly DateTimeKind _kind;
    private readonly BsonType _representation;

    public DateTimeSerializationOptionsConvention(DateTimeKind kind, BsonType representation)
    {
        _kind = kind;
        _representation = representation;
    }

    public void Apply(BsonMemberMap memberMap)
    {
        if (memberMap.MemberType == typeof(DateTime))
        {
            memberMap.SetSerializationOptions(new DateTimeSerializationOptions(_kind, _representation));
        }
    }
}
然后像这样使用它:

ConventionRegistry.Register(
    "dates as documents",
    new ConventionPack
    {
        new DateTimeSerializationOptionsConvention(DateTimeKind.Utc, BsonType.Document)
    },
    t => true);
