Can a Linq query retrieve BLOBs from a Sql Database?
And how do they come out?
回答1:
LINQ-To-SQL classes create properties of type System.Data.Linq.Binary for all binary and varbinary fields in SQL-Server. The Binary type has a .ToArray() method that returns a byte[], and its constructor can take a byte[].
Older versions of SQLMetal generated properties of type byte[], but the problem with these was that they failed in any joins. I think that's the main reason they replaced it with the IEquatable Binary type.
回答2:
If I'm not mistaken LINQ to SQL teats BLOB as System.Byte[]
I recall that there was some problem with SqlMetal, it generated wrong type for BLOB, but MSVS dmbl designer should work.
