FluentNHibernate CustomType(“Binary”) MappingException

发布于 2024-10-18 03:20:59 字数 923 浏览 1 评论 0原文

我在使用 NuGet（包版本：1.1.1.694）和 NHibernate 3.0 GA 上可用的最新 FluentNHibernate 构建映射实体时遇到问题

我想要达到的是 sql 类型：binary(64) 与 FluentNHibernate 以与数据库无关的方式（我不想使用 CustomSqlType）。

默认值是 varbinary(64) 我不想要。小写的“二进制”也会导致这种情况。

我的映射代码：

this.Map(x => x.PasswordHash)
    .CustomType("Binary")
    .Length(64)
    .Not.Nullable();

在 NHibernate 映射 XML 文件中给出：

<property name="PasswordHash" type="Binary">
  <column name="PasswordHash" length="64" not-null="true" />
</property>

生成架构时出现异常：无法加载二进制类型。 System.TypeLoadException：无法加载 Binary 类型。可能的原因：未指定程序集名称。

在 NHibernate.Util.ReflectHelper.TypeFromAssembly(AssemblyQualifiedTypeName name, Boolean throwOnError)

另一方面 CustomType("StringClob") 有效。我缺少什么吗？有没有办法让 FluentNHibernate .CustomType<>使用内置 NHibernate 类型？

（对于 AnsiChar 或 .NET 类型和数据库类型之间的其他非标准映射有用）？

I have an issue with mapping an entity with the latest FluentNHibernate build available on NuGet (package version: 1.1.1.694) and NHibernate 3.0 GA

What I am trying to reach is sql type: binary(64) with FluentNHibernate in a database-agnostic manner (I don't want to use CustomSqlType).

The default is varbinary(64) which I don't want. Lowercase "binary" leads to this as well.

My mapping code:

this.Map(x => x.PasswordHash)
    .CustomType("Binary")
    .Length(64)
    .Not.Nullable();

Gives in NHibernate mapping XML file:

<property name="PasswordHash" type="Binary">
  <column name="PasswordHash" length="64" not-null="true" />
</property>

Exception on generating schema:
Could not load type Binary.
System.TypeLoadException: Could not load type Binary. Possible cause: no assembly name specified.

at NHibernate.Util.ReflectHelper.TypeFromAssembly(AssemblyQualifiedTypeName name, Boolean throwOnError)

On the other hand CustomType("StringClob") works. Is there something I am missing ?
Is there a way to make FluentNHibernate .CustomType<> work with built-in NHibernate types ?

(Useful for AnsiChar, or other non-standard mapping between .NET type and database type) ?
