I now there is a demand in the Tick Timer trigger when passing parameters:
Basically it is

 
T.T ick +=(sender, args)=& gt; T_Tick (sender, args, I, end); 
Public static void t_Tick (object o, EventArgs e, 
Neo. ApplicationFramework. Tools. OpcClient. GlobalDataItem I, int the end) 
{
ImgChange (I, end); 
} 
Public static void imgChange (Neo. ApplicationFramework. View OpcClient. GlobalDataItem I, int the end) 
{
Int SRC=https://bbs.csdn.net/topics/i.Value; 
SRC=https://bbs.csdn.net/topics/src I.V alue=https://bbs.csdn.net/topics/src; 
} 

But this event how close?

 
Public static void timerOff (Neo. ApplicationFramework. View OpcClient. GlobalDataItem I, int the end) 
{
T.T ick -=(sender, args)=& gt; T_Tick (sender, args, I, end); 
T.E nabled=false; 
} 

Such complains is not applied to the instance? What reason?

CodePudding user response:

Because you are using the relationship between anonymous functions,
The method assigned to the event, and then directly + - event,

 System. Windows. Forms. The Timer t=new System. Windows. The Forms, the Timer (); 
Public EventHandler eve; 
Private void Form1_Load (object sender, EventArgs e) 
{
Eve=new System. EventHandler (aa, ee)=& gt; Tick (aa, ee, "111")); 
T.I nterval=3000; 
T.T ick +=eve; 
t.Start();//3 seconds to pop up a 111 
} 

Private void Tick (object sender, EventArgs e, string STR) 
{
MessageBox. Show (STR); 
} 

Private async void button1_Click (object sender, EventArgs e) 
{
T.S top (); 
T.T ick -=eve; 
t.Start();//check if still pops up 111 
}

Because two anonymous functions, though a Yang two peas in a pod, but the actual reference is not the same,
Like
The model m1=new model ();
M1=new model ();

The two new model (); Is a different object,

the Timer has been tried in the past, get lost, don't use FluentScheduler it sweet
