Question

in my mvc project im using nhibernate 3 as orm, but i have a problem with saving and loading images which their type is byte []

public class PersonImage  : PersistentObject
{
    private string _contentType;
    private byte[] _image;

    private Person _person;


    virtual public string ContentType
    {
        get { return _contentType; }
        set
        {
            if ( value != null && value.Length > 20)
                throw new ArgumentOutOfRangeException("Invalid value for ContentType", value, value.ToString());
            _contentType = value;
        }
    }

    virtual public byte[] Image
    {
        get { return _image; }
        set { _image = value; }
    }

     }



 public class PersonImageMap : ClassMap<PersonImage>
{
    public PersonImageMap()
    {
        Schema("personnel");

        Id(p => p.Id);

        Map(p => p.Image)
            .CustomSqlType("varbinary(MAX)")
            .Not.Nullable();

        Map(p => p.ContentType)
            .Not.Nullable();

        }

}

the problem is that i think this image cant be saved correctly because when i load it i just can see a part of image not the whole image!!

Answer 1

i found it
the length attribute should be defined in this case

 Map(p => p.Image)
            .Length(2147483647)
            .CustomSqlType("varbinary(MAX)")
            .Not.Nullable();
