如何解决这个泛型与仓库模式问题？ [英] How to solve this generic with repository pattern problem?

问题描述

我有一个前一个问题的代码，但不是编译：

  public interface IEntity 
 {
 //所有数据对象共有
} 
 public interface ICustomer：IEntity 
 {
 //客户的具体数据
} 
 public接口IRepository< T，TID> ：IDisposable where T：IEntity 
 {
 T Get（TID key）; 
 IList< T>得到所有（）; 
 void Save（T entity）; 
 T更新（T实体）; 
 //将在此添加常用数据
} 
 public class Repository< T，TID> ：IRepository 
 {
 //通用存储库的实现
} 
 public interface ICustomerRepository 
 {
 //客户存储库的特定操作
} 
 public class CustomerRepository：Repository< ICustomer> ICustomerRepository 
 {
 //实现特定客户资料库
} 
  / pre> 
 
 
但是在这两行中：
 
 
 
 1- public class Repository：IRepository 
 
 
 
 2- public class CustomerRepository：Repository，ICustomerRepository 
 
 
 
它给我这个错误：使用通用类型'TestApplication1.IRepository'需要'2'类型的参数
 
 
 
你可以帮我解决吗？
解决方案
从Repository / IRepository继承时，需要使用两个类型的参数，因为它们需要两个类型的参数。也就是说，当您从IRepository继承时，您需要指定以下内容：
  public class Repository< T，TID> ：存储库< T，TID>其中T：IEntity 
  
和
  public class CustomerRepository：Repository< ICustomer，int>，ICustomerRepository 
  
在Reposistory 
 
的实现中添加类型约束
I had this code from a previous question, but its not compiling:
    public interface IEntity
{     
// Common to all Data Objects
}
public interface ICustomer : IEntity
{
     // Specific data for a customer
}
public interface IRepository<T, TID> : IDisposable where T : IEntity
{
     T Get(TID key);
     IList<T> GetAll();
     void Save (T entity);
     T Update (T entity);
     // Common data will be added here
}
public class Repository<T, TID> : IRepository
{
     // Implementation of the generic repository
}
public interface ICustomerRepository
{
     // Specific operations for the customers repository
}
public class CustomerRepository : Repository<ICustomer>, ICustomerRepository
{
     // Implementation of the specific customers repository
}
But in these 2 lines : 

1- public class Repository : IRepository 

2- public class CustomerRepository : Repository, ICustomerRepository 

It give me this error: Using the generic type 'TestApplication1.IRepository' requires '2' type arguments 

can you help me solve?
解决方案
You need to use two type arguments when inheriting from Repository/IRepository because they take take two type arguments. Namely, when you inherit from IRepository, you need to specify something like:
public class Repository<T, TID> : IRepository<T,TID> where T:IEntity
and
public class CustomerRepository : Repository<ICustomer,int>,ICustomerRepository
Edited to add type constraint on implementation of Reposistory
