NHibernate：通用方法中的QueryOver

Question

我有這個測試方法，我對「List」方法有問題。我想使用幾個類（所有實現IAdminDecimal）。在QueryOver，我有這樣的錯誤： 類型「T」必須是爲了用它作爲參數「T」在通用類型或方法「NHibernate.ISession.QueryOver（）」

引用類型

using (var session = sessions.OpenSession()) 
{ 
    using (var tx = session.BeginTransaction()) 
    { 
     CurrentSessionContext.Bind(session); 

     AdministrationService service = new AdministrationService(session); 
     service.List<AdminDelay>(); 

     tx.Commit(); 
    } 
} 

類：

public class AdministrationService 
{ 
    private readonly ISession _session; 

    public AdministrationService(ISession session) 
    { 
     _session = session; 
    } 

    public IList<T> List<T>() where T : IAdminDecimal 
    { 
     var res = _session.QueryOver<T>().List<T>(); 
     return res; 
    } 
} 


public interface IAdminDecimal 
{ 
    int Id { get; set; } 
    int Code { get; set; } 
    decimal Value { get; set; } 
    bool IsDeleted { get; set; } 
} 

public class AdminVAT : IAdminDecimal 
{ 
    public virtual int Id { get; set; } 
    public virtual int Code { get; set; } 
    public virtual decimal Value { get; set; } 
    public virtual bool IsDeleted { get; set; } 
} 

Answer 1

嘗試：

public IList<T> List<T>() where T : class, IAdminDecimal 

Answer 2

嘗試看看這裏：

Is it possible to do create a generic Session.QueryOver<T>?
