Question

我需要验证架构，其中我有一个带有byte []属性（BLOB）的对象。当我运行验证时，我收到OverflowException：“对于Int32，值太大或太小。”

我正在使用NHibernate 3.1.0.400和FluentNHibernate 1.2.0.712 我已经创建了测试项目来检查。这是代码（它在验证时落下）：

static void Main(string[] args)
    {
        var configuration = new NHibernate.Cfg.Configuration();

        string connectionString = "some connection string";
        Console.WriteLine("Running test with connection string: {0}", connectionString);
        Dictionary<string, string> props = new Dictionary<string, string>()
                                               {
                                                   {"connection.provider", "NHibernate.Connection.DriverConnectionProvider"},
                                                   {"connection.driver_class", "NHibernate.Driver.MySqlDataDriver"},
                                                   {"connection.connection_string", connectionString},
                                                   {"dialect", "NHibernate.Dialect.MySQL5Dialect"},
                                               };
        configuration.AddProperties(props);
        var mappings = Fluently.Configure(configuration)
            .Mappings(m => m
                               .FluentMappings.AddFromAssemblyOf<DataResource>()
                               .Conventions.AddFromAssemblyOf<DataResource>());

        var sessionFactory = mappings
               .ExposeConfiguration(DoExtendedConfiguration)
               .BuildSessionFactory();
    }

    private static void DoExtendedConfiguration(Configuration configuration)
    {
        SchemaExport schemaExport = new SchemaExport(configuration).SetDelimiter(";").SetOutputFile("schema.sql");
        schemaExport.Create(false, true);

        SchemaValidator schemaValidator = new SchemaValidator(configuration);
        schemaValidator.Validate();
    }

 public class DataResource
{
    public int Id { get; set; }
    public byte[] Value { get; set; }
}
public class DataResourceMap : ClassMap<DataResource>
{
    public DataResourceMap()
    {
        Id(x => x.Id);
        Map(x => x.Value);
    }
}

我没有在官员身上找到关于此类错误的任何提及，但在我将FluentNhibernate和Nhibernate更新到最后一个可用版本（通过Nuget）之后，问题得以解决。那套我，所以我将关闭这个问题，好像没有人找到任何其他解决方案，堆栈允许我这样做。
