问题描述
大家好，
我在尝试从附加到Quartz.NET的内部类中调用函数时遇到一些问题.我进行了一些谷歌搜索，并(针对不良术语使用了策略)看起来像通常将基础(MainWindow)附加到内部类上.不幸的是，当我这样做时，Quartz停止工作.
问题?
如何在不破坏以下(IMyJob)接口的情况下从内部类调用基类中的函数?
代码
Hello All,
I am having some issues trying to call a function from an internal class attached to Quartz.NET. I did some googling and (apoligies for the bad terminology) it looks like normally you attach the base (MainWindow) to the internal class. Unfortunately when I do this, Quartz stops working.
The Question?
How do I call a function in the Base Class from an Internal Class without breaking the following (IMyJob) interface?
The Code
internal class SendAlarmCommand : MainWindow, IMyJob
{
public void Execute(JobExecutionContext context)
{
Console.WriteLine("In MyJob class : " + context.JobDetail.Name);
Console.WriteLine(string.Format("Running Alarm Job - {0}", System.DateTime.Now.ToString("r")));
JobDataMap dataMap = context.JobDetail.JobDataMap;
Console.WriteLine("Client ID - " + dataMap.GetString("ClientID"));
Console.WriteLine("Clock ID - " + dataMap.GetString("ClockID"));
Console.WriteLine("Command - " + dataMap.GetString("Command"));
string command = (dataMap.GetString("Command"));
Send(command); //Function in Main Window
}
}
internal interface IMyJob : IJob
{
}
抱歉，所提供的信息很少，我希望足够.我对这种事情还很陌生.
谢谢您提前提供的所有帮助，
Alex
Sorry for the the little information, I hope it''s enough. I''m still quite new to this sort of thing.
Thank you for all your help in advance,
Alex
推荐答案
您的接口没有成员，因此由于实现了该接口，因此其实现可能不会中断".在更一般的情况下，这也不是问题:任何类的任何方法都可以调用任何类的任何方法(静态方法)或类实例(实例方法)，而与接口实现无关.您可能面临的唯一问题是成员的声明与接口的成员冲突，但是可以使用 explicit接口成员实现解决此问题，请参见http://msdn.microsoft.com/en-us/library/ms173157.aspx [

Your interface has no members, so its implementation cannot be possibly "broken" due to the fact this interface is implemented. In more general case, it is also not a problem: any method of any class can call any method of any class (static method) or a class instance (instance method) without any concerns related to interface implementation. The only problem you might face is declaration of members conflicting with the members of interface, but this problem is resolved using explicit interface member implementation, see http://msdn.microsoft.com/en-us/library/ms173157.aspx[^].
If you face some problem ("stops working"), the reason is somewhere else; you did not provide enough information to see it.

Hello Sa，
感谢您的答复，但我在理解方面有些麻烦...
我浏览了一下代码，似乎找不到任何会引起冲突的东西，并且运行该程序也没有问题.唯一的问题是当我添加基类(
Hello Sa,
Thank you for the reply but I am having a little trouble understanding...
I had a look through the code and I can''t seem to find anything that would cause a conflict and the is no problem running the program. The only issue is when I add the base class (
internal class SendAlarmCommand : MainWindow, IMyJob)时，Quartz不会触发作业.
以下是我尝试使用的所有代码...如果您可以看一下，将不胜感激.
再次感谢您的帮助，
亚历克斯.
) Quartz does not trigger the Job.
Below is the all the code I am trying to get working... If you could take a look, that would be greatly appreciated.
Thank you again for your help,
Alex.
