C#调用计时器方法 [英] C# calling a timer method

问题描述

嗨 我有一个争论的方法(在服务应用程序上statrt(string [] args方法上)
然后我想调用一个方法(计时器方法(专用void timer1_Tick(object sender，EventArgs e)
通过此方法(启动方法)

我称此解决方案

 受保护的 覆盖  void  OnStart(字符串 [] args)
       {
           timer1_Tick( this ，e);
       } 

但是当我打电话时出现一个错误:

名称"e"在当前上下文中不存在

有解决方案吗?

解决方案

您好，

计时器需要一个名为"e"的EventArgs.
您没有名称为"e"的对象.

您可以像这样调用方法:

timer1_Tick(this，EventArgs.Empty);

是的，不要尝试传递不存在的东西.如果无法确定错误是正确的，那么我就茫然不知所措，因为您认为您正在使用编译器.

如果需要事件参数而没有事件参数，则使用EventArgs.Empty，这很明显.真正的程序员会考虑做某事的方法，并在您的计时器滴答声中调用它，而不是在计时器滴答声中调用它来做点什么，但这又是另一回事了.

hi i have a method with one arguement (at the service application & on statrt(string[] args method)
then i want to call a method (timer method (private void timer1_Tick(object sender, EventArgs e)
via this (start method)

i call this solution

protected override void OnStart(string[] args )
       {
           timer1_Tick(this , e);
       }

but when i call one error occurs:

the name ''e'' does not exist in the current context

any have a solution?

解决方案

Hello,

the Timer requires an EventArgs called ''e''.
You dont have an objekt with the name ''e''.

You can call the Method like this:

timer1_Tick(this, EventArgs.Empty);

Yes, don''t try to pass something that does not exist. If you can''t work out that the error is correct, then I am at a loss what it is you think you''re doing with a compiler.

EventArgs.Empty is what you''d use if you need event args and don''t have any, as is clearly the case here. A real programmer would factor out the method that does something, and call it in your timer tick, rather than call a timer tick to do something, but that''s another story.
