我在Windows 7上使用proc sql noprint;
create table newtable as
select var2
from mytable
where var1<value;
quit;
dll中的MongoDB.Driver 2.7.0，而不是配置了单个副本集的本地安装社区服务器4.0.2。
我正在侦听集合上的更改流，但是当我仅尝试访问生成的net461/netstandard2.0的{{1}}属性时，它将引发异常：
ClusterTime看看支持文档，ChangeStreamDocument确实是 private static DateTime? GetTimeStamp(ChangeStreamDocument<T> csd)
{
try
{
var clusterTime = csd.ClusterTime; // BOOM
return clusterTime.ToNullableUniversalTime();
}
catch
{
return null;
}
}
System.FormatException

：
clusterTime这是错误/已知问题还是我的设置有问题？
答案 0 :(得分：0)
MongoDB已确认这是一个错误。
