Hello
i have 2 picturebox each has event Mousedown ,i need to suscripe this event 
so i can call this event like Fun[i]
i think function to pointer could do this, but becuase it has to be in 
Unsafe,i do not like it .My problem is could not convert SampleDelegate to private void 
look at this
            SampleDelegate[] Fun = { EventMouse_0, EventMouse_1 };

What I have tried:

SampleDelegate[] Fun = { EventMouse_0, EventMouse_1 };

for(i=0;i<2;i++)
{
//assume in the next line the mouse has enter to one of the two pictureBox
Fun[i];
}
//private void mymouseDown(object sender, MouseEventArgs e)
privat void EventMouse_0()//mouseDown 
{
messageBox("U are in picturebox_0");
}

privat void EventMouse_1()//mouseDown
{
messageBox("u are in picturebox_1");
}

2 solutions

Solution 2

private void FormLoad(object sender, EventArgs e)
     {
         this.pictureBox1.MouseDown += new System.Windows.Forms.MouseEventHandler(this.pb1MouseDown);
         this.pictureBox2.MouseDown += new System.Windows.Forms.MouseEventHandler(this.pb2MouseDown);
     }

// i added

MouseEventHandler

for each pictureBox together with a formLoad above this solve my question
no need for the for loop below

for(i=0;i<2;i++)
{
//assume in the next line the mouse has enter to one of the two pictureBox
Fun[i];
}

thank you very much

NB: The new System.Windows.Forms.MouseEventHandler part hasn't been required since C# 1.0; you can simply use:

this.pictureBox1.MouseDown += this.pb1MouseDown;
this.pictureBox2.MouseDown += this.pb2MouseDown;

Solution 1

If you subscribe to a physical event, then when the subscriber is called, it receives a reference to the control that received it. See Control.MouseDown Event (System.Windows.Forms) | Microsoft Docs[^].
