Generate 100 buttons, 10 horizontal 10 Vertical

}
Create a new thread

Counter summation

Display count in form

Thread Sleep 1 seconds

}
});

}
Used to empty dynamically generated buttons in a form
void Removecontrol ()

Break
}
}
}
}
}
Auto-generated button events

Show Game Information

}
}
Get the number of clicked buttons

foreach (Control C in controls)//Traversal control collection
{
The number of control that is used to find the Enable property to False in the form
if (!c.enabled) {

}
}
Return temp. ToString ();//Returns counter information
}
Close the form
private void Form1_formclosing (object sender, FormClosingEventArgs e)
{
Environment.exit (0);//forcibly closes the form, the application forces the exit.
}
}
}
