Wcf 如何正确实施具有两个接口的策略模式？

我创建了一个服务数据访问层，其中有多个数据库，数据需要来自这些数据库

我在一个数据库中做得很好，我在其中定义了包含成员详细信息的

memberRepository

。但是，现在我必须获取存储在另一个数据库中的与会话相关的详细信息

运营合同：

• IMemberServices

  包含

  GetLoggedInBuddies（int profileID）

• ISessionServices

  包含

  GetProfileIDFromSessionID（字符串sessionID）

我的服务级别：

public class MemberService : IMemberService, ISessionServices
{
    #region Strategy pattern configuration

    //
    // Member repo
    // 
    private MemberRepository memberRepository;
    public MemberService()
        : this(new MemberRepository())
    { }
    public MemberService(MemberRepository memberRepository)
    {
        this.memberRepository = memberRepository;
    }


    //
    // Session repo
    //
    private SessionRepository sessionRepository;
    public MemberService() : this(new SessionRepository()){}
    public MemberService(SessionRepository sessionRepository)
    {
        this.sessionRepository = sessionRepository;
    }

    #endregion



    /// <summary>
    /// Session-related details are maintained in the Secondary database
    /// </summary>
    /// <param name="sessionID"></param>
    /// <returns></returns>
    public int GetProfileIDFromSessionID(string sessionID)
    {
        int sessionProfileID = sessionRepository.GetProfileDetailsFromSessionID(sessionRepository);

        return sessionProfileID;
    }

    /// <summary>
    /// Try profileID = 1150526
    /// </summary>
    /// <param name="profileID"></param>
    public void  GetLoggedInBuddies(int profileID)
    {
        memberRepository.GetLoggedInBuddies(profileID);
        //return memberRepository.GetLoggedInBuddies(profileID);
    }

我只需要一个人帮我把它组装起来

谢谢。

我不确定您的问题，但您可以使用不带参数的ctor，并为每次回购使用参数

public MemberService()
{
   this.memberRepository = new MemberRepository();
   this.sessionRepository = new SessionRepository();
}

我创建了一个中央存储库，它接受我要连接到的数据库的连接字符串的名称

public abstract class DatabaseRepository : BaseRepository
{
    static IDbConnection connection;

    /// <summary>
    /// Handles db connectivity as Dapper assumes an existing connection for all functions
    /// Since this app uses three databases, pass in the connection string for the required db.
    /// </summary>
    /// <returns></returns>
    protected static IDbConnection OpenConnection(string connectionStringName)
    {
        try
        {
            connection = new SqlConnection(WebConfigurationManager.ConnectionStrings[connectionStringName].ConnectionString);
            //connection = SqlMapperUtil.GetOpenConnection(connectionStringName);       // if we want to use the Dapper utility methods
            connection.Open();
            return connection;
        }
        catch (Exception ex)
        {
            ErrorLogging.Instance.Fatal(ex);        // uses singleton for logging
            return null;
        }
    }
.

这是答案还是问题？如果它是答案，请标记它。

public abstract class DatabaseRepository : BaseRepository
{
    static IDbConnection connection;

    /// <summary>
    /// Handles db connectivity as Dapper assumes an existing connection for all functions
    /// Since this app uses three databases, pass in the connection string for the required db.
    /// </summary>
    /// <returns></returns>
    protected static IDbConnection OpenConnection(string connectionStringName)
    {
        try
        {
            connection = new SqlConnection(WebConfigurationManager.ConnectionStrings[connectionStringName].ConnectionString);
            //connection = SqlMapperUtil.GetOpenConnection(connectionStringName);       // if we want to use the Dapper utility methods
            connection.Open();
            return connection;
        }
        catch (Exception ex)
        {
            ErrorLogging.Instance.Fatal(ex);        // uses singleton for logging
            return null;
        }
    }

using (IDbConnection connection = OpenConnection("FirstDBConnectionString")) { ...
