从另一个团队实现接口

Question

我收到了另一个团队的api和一些代码片段。我不确定如何让ApiTest工作。前两个片段是提供给我的。最后一个是我尝试实现界面并使其正常工作......

using com.XXXX.api;
class ApiTest
{
    static void Main(string[] args)
    {
        MicrositesApiFactory factory = MicrositesApiFactory.getInstance();
        Logger logger = factory.getLogger("ApiTest", typeof(Program));
        logger.error("created logger");

    /*  
    if (logger.isTraceEnabled)
    {
        logger.trace("acquired logger successfully");
    }
    */
        DatabaseMgr databaseMgr = factory.getDatabaseMgr("microsites");
    if (databaseMgr == null)
    {
        //logger.alert("unable to retrieve DatabaseMgr object");
    }
    else
    {
        DbConnection conn = databaseMgr.getDbConnection(DatabaseSchema.ApplicationSchema);
    }
    Console.In.ReadLine();
}

无论出于何种原因，他们在方法之后都包含了{...}。我不确定我需要在这做什么。 他们提供的界面：

namespace com.XXXX.api
{
    public class MicrositesApiFactory
    {
       public static MicrositesApiFactory getInstance() {...}
       public Logger getLogger(String msId, Type type) {...}
       public DatabaseMgr getDatabaseMgr(String msId) {...}
    }
    public abstract class Logger
    {
       public String MicrositeId { get; set; }
       public abstract void alert(String message);
    }
    public enum DatabaseSchema
    {
       ApplicationSchema,
       ConsumerSchema,
       ContentSchema
    }
    public abstract class DatabaseMgr
    {
       public String MicrositeId { get; set; }
       protected DatabaseMgr(String micrositeId) { ... }
       public abstract DbConnection
       getDbConnection(DatabaseSchema schema);
    }
}

以下是我对界面的改编以使其正常工作。 我不知道最好的办法是什么。 根据我对Interfaces的理解，我需要实现所有方法。 任何关于实现接口的建议都是受欢迎的。

此错误是唯一剩下的错误：

  

DatabaseMgr不包含带0参数的构造函数

using System;
using System.Data.Common;
using System.Data.SqlClient;

namespace com.tsystems_mms.phi.microsites.api
{

    public class MicrositesApiFactory : Logger
    {

        public override DbConnection getDbConnection(DatabaseSchema message)
        {
            DbConnection test = new SqlConnection();
            return test;
        }


        public DatabaseMgr getDatabaseMgr(String msId)
        {
            DatabaseMgr test = new MicrositesApiFactory();
            return test;
        }

        public static MicrositesApiFactory getInstance() {
            return new MicrositesApiFactory();
        }

        public override void alert(string message) { }

        public override bool isErrorEnabled
        {
            get { throw new NotImplementedException(); }
        }

        public Logger getLogger(String msId, Type type)
        {
            Logger test = new MicrositesApiFactory();
            return test;
        }

    }
    public abstract class Logger : DatabaseMgr
    {
        public new String MicrositeId { get; set; }
        public abstract void alert(String message);
        public abstract bool isErrorEnabled { get; }
    }
    public enum DatabaseSchema
    {
        ApplicationSchema,
        ConsumerSchema,
        ContentSchema
    }
    public abstract class DatabaseMgr
    {
        public String MicrositeId { get; set; }

        protected DatabaseMgr(String micrositeId)
        {
        }

        public abstract DbConnection getDbConnection(DatabaseSchema schema);
    }
}
