C＃接口存儲庫方法中的不同變量類型

Question

我想實現一個接口和存儲庫模式。 我不同的存儲庫可以具有類型數據類型，

第一個是（String-int，char-long）

第二個是（字符雙，雙字符串）。 模式不斷發展，我們有大約50種不同的方法，我們正在將接口/存儲庫更改為另一個數據庫系統等。

如何編輯下面的界面，以允許不同的數據類型？ 謝謝，

public interface ITransactionRepository
{
    void SearchTransactionbyCategoryCustomerId(Category, CustomerId ); // what should I write here?
    void SearchTransactionbyProductDepartment(Product, Department); 
    ......
}


public class TransactionRepository1: IRepository
{
    void SearchTransactionbyCategoryCustomerId(string Category, int CustomerId);
    void SearchTransactionbyProductDepartment(char Product, long Department); 
    ......
}

public class TransactionRepository2: IRepository
{
    void SearchTransactionbyCategoryCustomerId(char Category, double CustomerId);
    void SearchTransactionbyProductDepartment(double Product, string Department); 
    ......
}

Answer 1

將您的接口定義為通用接口，並在實現中指定實際的類型，

public interface ITransactionRepository<TCategory, TCustomerId, TProduct, TDepartment>
{
    void SearchTransactionbyCategoryCustomerId(TCategory Category, TCustomerId CustomerId );
    void SearchTransactionbyProductDepartment(TProduct Product, TDepartment Department); 
    ......
}


public class TransactionRepository1: ITransactionRepository<string, int, char, long>
{
    void SearchTransactionbyCategoryCustomerId(string Category, int CustomerId);
    void SearchTransactionbyProductDepartment(char Product, long Department); 
    ......
}

public class TransactionRepository2: ITransactionRepository<char, double, double, string>
{
    void SearchTransactionbyCategoryCustomerId(char Category, double CustomerId);
    void SearchTransactionbyProductDepartment(double Product, string Department); 
    ......
}
