Is there any easy method to do this?

[jlo6687]

there are 64 buttons(button1,button2....button64).
Also a textbox and button "ok ".

when 15 is entered into the textbox and clicked ok Backcolcor of button15 shauold change to red;

my Approach is
1.valve entered is passed to i
2.then using while loop i change the back color to red
while(i==15)
{button15.Backcolor=Color.red;
}

Above approach works but needs 64 while loops and that makes the code lenghty.


is there any method to reduce the code

i want to know wheather i can use "button"+i.tostring(); here to reduce the code

First, no, you cannot build a string and use it to reference a variable.

Second, why would you use a loop if there is nothing to repeat? You're using "while" statements as if they were "if" statements.

If I had to do something like this, I would create the buttons in code, in a proper "for loop", rather than in the designer. And as I created them, I would add them to a System.Collections.Generic.Dictionary<int,Button>.

Dictionary<int, Buttons> buttonsDict = new Dictionary<int, Buttons>();
for(int i=1; i<=64; i++)
{
  Button b = new Button();
  //set all of button b's attributes
  buttonsDict.Add(i, b);
}
 

Now, later, when your user wants to change the background, let's say they typed in "15". You can get that button reference like this:

buttonsDict[15].BackColor = Colors.Red;
