I've faced the problem with Dapper FluentMap (version 1.60) which I don't know how to fix. It looks like Dapper can't map a column from a table if the corresponding property in .NET class has "Date" name.
I have the table in DB (I'm using MS SQL if that's matter) with column Dt
of Date
type.
There is an entity with DateTime property:
public class MyEntity {
public DateTime Date { get; set; }
}
and the corresponding mapping:
public class MyEntityMapper : EntityMap<MyEntity> {
public MyEntityMapper() {
Map(p => p.Date).ToColumn("Dt");
}
}
When I try to get data from the DB and map to MyEntity
, I get the following error:
ArgumentNullException: Value cannot be null. Parameter name: meth
If I rename Date
property in MyEntity
to something else like Dt
or JustDate
- everything works fine. Is there such restriction in Dapper Fluent Map (not allowed to give a name to property equal to data type name in DB)?
If so, is it possible to overcome it somehow? Because in my case it's a bit problematic to rename property in MyEntity

Yes you are right, the only solution you can do was to change your entity property Date into other name.
