需要System.String,得到System.Guid

我正在使用S#arpArcitecture 1.6。在64位Windows7上安装。

{“提供了错误类型的id。应为:System.String,get System.Guid“}System.Exception{NHibernate.TypeMismatchException}

1 public Category GetCategory(Guid id)
2    {
3        Category cat = categoryRepository.Get(id);
4        return cat;
5    }

表(SQL Server 2008)

CREATE TABLE [dbo].[MasterCategories] (
    [masterCategoryId] [uniqueidentifier] ROWGUIDCOL  NOT NULL,
    [organizationId] [nchar](5) NOT NULL,
    [categoryNumber] [nvarchar](25) NOT NULL
)

实体定义

public class Category : EntityWithTypedId<Guid>

public void Override(AutoMapping<Category> mapping)
    {
        mapping.Table("MasterCategories");

        mapping.Id(x => x.Id).Column("masterCategoryId");
        mapping.Map(x => x.Number).Column("categoryNumber");

        mapping.References(x => x.Organization)
            .Column("organizationId")
            .Cascade.All();
    }

存储库接口

public interface ICategoryRepository : IRepositoryWithTypedId<Category,Guid>
{
}

存储库

public class CategoryRepository : 
             RepositoryWithTypedId<Category,Guid>, 
             ICategoryRepository
{ }
