Hi, I have upgraded from NHibernate 2.1 to NHibernate 3.0 GA and I have hit a regression. I have an entity with an Image property of type System.Drawing.Image and I have mapped it like this:
The Image column in the table is of type varbinary(MAX) in a MySQL Server 2008 Express database and I am using the MsSql2008 dialect.
While in NHibernate 2.1 this works perfectly fine in NHibernate 3.0 GA it breaks with the exception below when retrieving the entity back from the database:
If I serialize the Image myself with a BinaryFormatter the resulting byte array is more than 8000 bytes, but I see that the NHibernate code is deserializing only the first 8000 bytes. Maybe varbinary(MAX) is not handled correctly?

Sorry I meant ETA on version 3.1.0.
Tim Hughes February 23, 2011 at 3:03 PM
Is there an ETA on version 3.0.1? I too am running into the 8k barrier. I tried the mapping described by Michael Teper and that doesn't work. I'm trying to save image data to a database, but every image I upload after making Michael's change has an additional 28 bytes added. The database column I'm writing to is defined as a varbinary(max). The C# class defines the property that holds the data as type byte[]. The mapping file has the exact property mapping as defined by Michael (with the Name attribute changed of course). This did work with version 2.1.2. Unfortunately I am days away from moving my code into production and would like to get access to version 3.0.1 ASAP.

Until 3.0.1, the following mapping seems to do the trick:
Hi,
I have upgraded from NHibernate 2.1 to NHibernate 3.0 GA and I have hit a regression.
I have an entity with an Image property of type System.Drawing.Image and I have mapped it like
this:
<property name="Image" type="System.Drawing.Image, System.Drawing, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
<column name="Image" length="2147483647" not-null="false" />
</property>`
The Image column in the table is of type varbinary(MAX) in a MySQL Server 2008 Express database and I am using the MsSql2008 dialect.
While in NHibernate 2.1 this works perfectly fine in NHibernate 3.0 GA it breaks with the exception below when retrieving the entity back from the database:
If I serialize the Image myself with a BinaryFormatter the resulting byte array is more than 8000 bytes, but I see that the NHibernate code is deserializing only the first 8000 bytes. Maybe varbinary(MAX) is not handled correctly?
