是否可以修改c＃Windows窗体中的控件集合？ 怎么样？

Question

The C# windows form has 8 buttons. I want to change the text of each button. Those texts are random numbers without repetition. I know how to generate random numbers without repetition but I don't want write 8 instructions to assign each number to each button text respectively like this:

                   button1.Text = listNumbers[0].ToString();
                   button2.Text = listNumbers[1].ToString();
                                     .
                                     .
                                     .

Is it possible to modify a collection of buttons in c# windows form such as using a loop? If yes, how to write these codes and their pseudocodes? Thanks.

Answer 1

You can use form's Controls collection for changing text of buttons like below.

foreach(var control in this.Controls)
{
    if(control is Button)
    {
        ((Button)control).Text = "New Text";
    }
}

Answer 2

You can use LINQ's OfType<T> with the Controls property:

foreach (var button in Controls.OfType<Button>()) // will only give you Buttons
{
    button.Text = "some text";
}
