我有一个工作项目,其中包含诸如计算,串行端口等的单独类。并且希望将它们封装到dll中以用于其他类似项目。我试图实现一个工厂,首先是一个串口工厂,所以我可以在多个dll之间使用。这是我第一次阅读大量的教程并开始使用这个例子:

它的效果很好,但是我想将FileLogger移到它自己的类中,所以我已经尝试了一段时间,但需要在正确的方向上轻推一下吗?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace FactoryPatternSample
{
interface ILogger
{
void Log(string Message);
}
enum LoggerType
{
File,
Database,
EventViewer
}
public class File
{
public class FileLogger : ILogger
{
public void Log(string Message)
{
Console.WriteLine("{0} - Logged in File.", Message);
}
}
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace FactoryPatternSample
{
class Program
{
File.FileLogger flogger = new File.FileLogger();
interface ILogger
{
void Log(string Message);
}
enum LoggerType
{
File,
Database,
EventViewer
}
class DatabaseLogger : ILogger
{
public void Log(string Message)
{
Console.WriteLine("{0} - Logged in Database.", Message);
}
}
class EventViewerLogger : ILogger
{
public void Log(string Message)
{
Console.WriteLine("{0} - Logged in EventViewer.", Message);
}
}
class LoggerFactory
{
public static ILogger Get(LoggerType type)
{
switch (type)
{
case LoggerType.Database:
return new DatabaseLogger();
case LoggerType.EventViewer:
return new EventViewerLogger();
case LoggerType.File:
default:
return new flogger();
}
}
}
static void Main(string[] args)
{
ILogger logger1 = LoggerFactory.Get(LoggerType.Database);
logger1.Log("Message from Main");
ILogger logger2 = LoggerFactory.Get(LoggerType.File);
logger2.Log("Message from Main");
ILogger logger3 = LoggerFactory.Get(LoggerType.EventViewer);
logger3.Log("Message from Main");
Console.ReadKey();
/*Output
Message from Main - Logged in Database.
Message from Main - Logged in File.
Message from Main - Logged in EventViewer.
*/
}
}
}
这一位是导致问题的原因:
return new flogger();
这是错误:
错误CS0246类型或命名空间名称' flogger'找不到(你错过了使用指令或汇编引用吗?)
我无法让它引用File.FileLogger,请帮忙吗?
答案 0 :(得分:0)
解决了,一旦我删除了:
src
来自程序类,结束了它现在可以工作,因为我有两个接口
