问题:

代码是在多get='_blank'>线程环境下，做了简单的Key是否存的判断, 测试代码如下:

public class Program  {    static Dictionary<string, Logger> loggreDic;    static object loggerDicLocker = new object();    public static void Main()    {      loggreDic = new Dictionary<string, Logger>();      for (int i = 0; i < 100; i++)      {        ThreadPool.QueueUserWorkItem(o =>        {          try          {            var logger = GetLogger("AAA");          }          catch (Exception)          {            Console.WriteLine(string.Format("弟{0}个线程出现问题", o));          }        }, i);      }      Console.ReadKey();    }    static Logger GetLogger(string cmdId)    {      if (!loggreDic.ContainsKey(cmdId))      {        loggreDic.Add(cmdId, LogManager.GetLogger(string.Format("ChinaPnrApi.{0}", cmdId)));      }      return loggreDic[cmdId];    }  }
