非静态字段需要对象引用. [英] An object reference is required for the non-static field...

问题描述

如何在此函数中调用存储过程

称为Jobs.cs的类

how to call stored procedure in this function

a class called Jobs.cs

namespace myScheduler
  {
      public sealed class Jobs
      {
          public Jobs(){}

          public static void DailyJob(object state)
          {
             //Your dream goes here.
          }
               ...
           }
           ...
        }

我想在(DailyJob)函数中调用过程，而这是我在调用过程DailyJob时出现的错误:

An object reference is required for the non-static field, method, or property ''myScheduler.Jobs.con

删除静态词时出现另一个错误:

An object reference is required for the non-static field, method, or property ''myScheduler.Jobs.DailyJob(object)''

I want to call procedure in (DailyJob) function and this is the error when I call procedure DailyJOb:

An object reference is required for the non-static field, method, or property ''myScheduler.Jobs.con

when remove static word another error :

An object reference is required for the non-static field, method, or property ''myScheduler.Jobs.DailyJob(object)''

TimerCallback callbackDaily = new TimerCallback(Jobs.DailyJob);

推荐答案

MSDN页面上有一个很好的例子 [TimerCallback <的href ="http://msdn.microsoft.com/en-us/library/system.threading.timercallback.aspx" target ="_ blank" title ="New Window"> ^ ]

在该示例中，Callback方法不是静态的，并且在调用它之前创建了该类的实例:

There is a good example on the MSDN page[^] for TimerCallback

In that example the Callback method is not static and an instance of it''s class is created prior to calling it:

Jobs myJobs = new Jobs();
TimerCallback callbackDaily = new TimerCallback(myJobs.DailyJob);

那就是没有 static访问修饰符.

That is without the static access modifier.
