It is possible to serialize and write file in database with Nhibernate?

public virtual File Arquivo { get; set; }

He does not let map and did not want to record without using Nhibernate to follow the pattern

c# nhibernate

  • It is possible. How do you map the classes?

  • If it is similar to Entityframework, you should map a byte[] property to the field in the database that represents this file (varbinary for example).

Yes, it is possible. In C# the type has to be byte[] and not File.

Not least because File is a static class, you will never be able to use an instance of File.

In the mapping would be:

Property(x => x.Arquivo, map =>
{
    map.Type(NHibernateUtil.BinaryBlob);
    map.Length(Int32.MaxValue);
});

  • Thanks for the help, I used as follows: public virtual byte[] Arquivo { get; set; } byte[] FileSream = File.ReadAllBytes(txtArquivo.Text);
 Objeto.Arquivo = FileSream; apparently recorded normally, now I’m searching how to return this information and write the file in a directory.
